L2TP works if I connect from internal wifi. When I try to connect from outside (3G) through WAN interface, unable to see the server.

My config:

WAN -- Linksys RV042 -- RB750GL

I already enable port forward in Linksys RV042.
1) UDP port 1701
2) UDP port 500

The log from Linksys shows that external connection received and forwarded at port 500, however the RB750GL does not receive the data. (I did not see any port 500 connection in IP-->firewall-->connection)

I suspect the RB750GL's default firewall setting is causing the problem. Can I delete all the setting under the firewall rules?

Just disable the firewall rules (each and everyone) by clicking on the Cross symbol. You can reactivate it by clicking the Tick symbol

I am running a L2TP transparent VPN between 2 mikrotik routers, no issues.

What are you doing with your RV042?
Having 2 router setup can really complicate matters...

Your mikrotik is connected as a ROUTER? or as a switch? what is the purpose of your Mikrotik?

I own and used many cisco, I was using 2611, 1841, 2811, 2821 etc, even have few unit of fortigate. All this are still with me. I am using Mikrotik for testing. The reason why I am using mikrotik is the size and option when cilent / prospect request for more option. I can spend money on network equipments but need to learn before investing into higher end model I start cisco with 1720, 1721 and all the way up to 38xx series.  Money to spend for equipments is not an issue for me, I need to pickup the knowledge and learn how to do support so when customer/prospect ask I know how to answer.

Possible of Mikrotik  is giveng cheaper solution, but need to have solution that work. Cheap solution but must work.

I don't have to spend thousand for support from Cisco because the product and OS are pretty stable when it realase. Only when need to have implementation service we have to pay Cisco.

I have spend effort to learn mikrotik, and some function claim usable but when try are not to name a few the build in  external antenna extension, the Gigabit port. With me now  2 units RB751U, 3x 250, and RB411. I don't buy the highest end until know the product work.
*
For testing purposes, pickup up the 750G (gigabit model). Cheap and good.
All their gigabit models, have got faster CPU and more ram than NON gigabit models.

To be fair to both Mikrotik and Cisco users (or fanboys), we will compare routers/switches of the same price point.

So to be fair, we shouldn't compare a RM3000 Cisco vs RM500 Mikrotik.
It is like comparing a Lambo and a GTR.

I would say that Mikrotik has a good Feature to Price ratio, while the Cisco (market leader) has got better support and many great innovative features.

I once had a customer that require VPN services (point to point transparent VPN). On the Mikrotik, we using software to encrypt/decrypt with no dedicated hardware. The only models with hardware is on their top end routers.
My customer picked the Mikrotik over the alternative router with hardware VPN, because of their budget constraint. With their minimal traffic through the VPN, a software implementation was sufficient.

Doesn't matter which brand you get, Cisco or Mikrotik. If you don't know how to use it, you won't maximise its potential.

Even if my customer request for a Cisco tomorrow, I would have trouble setting 1 up (the last time I maintain/use one was 12 years ago, a 4600 and 6500 series).

We are here to discuss and "try" to help each other.....


PS: Is Fortigate really that good? I have a few questions if you are familiar with a Fortigate 50B.

Sure need to compare at the correct type. Is unfair to compare in a difference league. Mikrotik need to do the basic things right. I got my mikrotik free (the rb411) from a client who try upgrade the stable release firmware but brick that unit. Got to help him replace with a basic AP. Lucky can still un brick with the manual way and got it FOC smile.gif

Basic function like what mention above need to get it right. Stable release upgrade need to be seamless. A Gigabit ports need to be able to support gigabit speed. Not until users raised issue and only say it need major rewrite of code. Is like buying a car that suppose to support 5 person weight and later when 5 people sit on it car got problem moving.

I am helping a friend to setup few whitebox esxi with one NIC per white box, but support VLAN, planing to make few VLANs, Data and iSCSI VLAN at minimal cost, need an independent iSCSI path to NAS for stable connection. Was doing some research on Rb2011 and found th  gigabite problem. Hope they get it fix and I can help him setup. ESXi already up just waiting to connect to a bigger NAS for data exchange and simulation. Maybe need to ask him buy one and try, if can't I take home and play until it resolved smile.gif

Using fortigate 60c still learning and testing, it have lots of function build in e.g. antivirus, proxy, Some L7 firewall features. But got to pay yearly maintenance fees sad.gif  Is not really a router, more like an hybrid. You need to think it as a firewall with router features. You also use fortigate? Do you know how to enable ingress and engress like Cisco Netflow? Need to have detail traffic monitor to catch bandwidth hogger..
*
I don't use Fortigate. My customer had a 50B (maitenance contract expired), but having issues with it. Sometimes on heavy load, it will just "lag". After disabling almost every feature... it still lags. The latency on peak period could be like 10 secs before there is a response. He told me, company started small, but at this size maybe the Fortigate cant handle the load. In the forum, some said to flash to earlier firmware, which are more stable and efficient...

In the end, we just test with my "standby/testing" 751G on 40+ users. No more issues with "lag". Waiting for them to order a RB2011UAS. The issue now is they using those home grade wireless routers as AP. Some would just "hang" when too many users try to connect. Told them to get some Ubiquiti APs, but customer said will upgrade in stages because of limited budget. Will implement a 2 VLAN on 2 seperate broadband services when the 2011UAS comes in with backup failover. Total users should peak at 60+.

Back to your GB issue, I agree that it should just work out of the BOX. Not sure about the Auto-Neg issue (just goggle it). My 751G and 750G no issues when connecting to GB Switch. I just checked 2 of my customers RB2011, also no issue when connecting to GB Switches. However I noticed that the GUI is only showing 100MB, while when I use command line, it shows GB with Full Duplex.

Did you know there is a "master port" on the Mikrotik, features where the ports are linked together like a "switch" giving you wire speeds, without any CPU utilization. If the packet is NOT meant for the switch (layer 2), it will pass to router (layer 3). I would suggest "switching" the ports together reducing the CPU usage and getting closer to Wire speed. When you test your throughput, remember to enable the "master port". And if you could, disable it and see what is the difference tongue.gif

And in Mikrotik got Traffic Flow (IP-> Traffic Flow) feature, where it is NetFlow compatible. I think they support V5 and V9 of netflow. What software you use to monitor? I am using PRTG. Is there a better one?


If you want to pinjam my "standby/testing" 751G unit, you can after I install for my customer next week.

Hmmm... I am running it behind my NAS and I am not getting consistent speed with LACP. Perhaps have something to do with this auto negotiate issue. From the thread you posted, someone mentioned that the problem have not been sorted yet.
*
I have just installed the RB2011UAS and checked all the 5 GB ports using 2 laptops (with GB connection) and finally to a 24 Dlink GB Switch. No issues with auto neg.

I think this is issue only between routers....

In theory it should work.

But since I don't have any hardware with bonded support, I am not able to give you any feedback/opinion.

Tried the Mikrotik User Forums?

I just follow Mikrotik wiki tutorial http://wiki.mikrotik.com/wiki/Limiting_a_u...t_of_traffic_II

It doesn't working for me to limit the daily usage, I just create a script for daily quota. Am I doing something wrong?
*
Easiest is to create a HotSpot service, and giving each user a limit (hours and/or bandwidth). You can then set a script to reset the limits each month....

You need to get the Data and Info Channel correct.

Either you find the settings online, or you just trial an error.

If you get the correct Channel, your unit will connect automatically.

Hi,
Anyone can suggest a replacemet model for maxis fibre/iptv router technicolor TG784n v3?

as mentioned, i need at least 3 lan port and 1 post for voip.
*
I setup for a customer using Maxis Fibre Modem and Maxis Router.

We had to still use the Modem, and the VOIP through the modem.

All internet function was forwarded to a Mikrotik router.

So depending on whether you have the "admin" password to your Maxis Fibre modem, it would be possible.... all we need to know is the VLAN IDs.... for each service

PM me if you need more info.

Hi I am interested on learning RouterOS, as i have the very basic knowledge in networking, is there anyway i can have the online training and is there anyone can share your experience about how good is RouterOS?

May i know how routerOS benefit on below setup?

Network cable are using CAT5E 100Mbps.
1 x 24 ports DES 1024R
1 x 24 ports DES 1024A
1 x Linksys LRT224 (router firewall)
1 x Dlink ADSL 2750E ADSL Modem
1 x Innacomm 3400v ADSL Modem
1 x Dlink NAS 323

besides on that, there are a lot of small 5ports or 8 ports normal switches connected to some other location for ports extension purpose. 

My target plan want to improve the current network speed and prepare for future ERP system.
*
Even with experience running Cisco OS (many years ago) and got good knowledge in Networking.... I found it difficult setting up the RouterOS when I received by first unit. The syntax is all different, not to mention that everything is "manual" setup, including NAT, which is like auto on most "home routers"

Nowadays, they have some standard pre-set mode, which makes it easier. But I would reckon you would need to have good knowledge in Networks first, before attempting to use RouterOS.

If you are running ERP over LAN network, I doubt the RouterOS can help much, since its all LAN (unless you want to do QOS/queue). However if you want to setup Firewall, VPN or other services, I believe RouterOS can help you. But setup is not gonna be easy....

Be patient, and google for sample scripts, and work your way....

Yes, I plug in a good SFP on my RB4011, it didn't show any Vendor name or any other information. But when I plug in my RB5009 it show.
*
I had similar issue with the HEX POE model. SFP cant detect in that, but works in Ubiquiti switch.

Not sure firmware or hardware compatibility.....

I didn't try any further because it was for testing purposes


On a side note, the same SFP, might sometimes work in the same Switch (Huawei)... and not on the another Switch (Same model/firmware/make)
I don't have much experience with SFP, those that work, just work... those that don't really work... always have some issues.....

Sometimes branded also issue... sometimes no brand, works well... i really no idea which brand is "highly" recommended
