Bro,

I need your advice,

Is there an easy way to configure RB751G 2HnD to use 3G USB Modems ( one or two modems at one go via USB Hub) , i read there are ways of doing it but i found that they are quite complicated as i dun have a programming background

Thanks

To program 3G is easy.... got lots of tutorial online.... dont need much programming...

but still harder than DD-WRT or stock firmware from Dlink/Asus/TP Link....

start at wiki.mikrotik.com....

I dont think you can connect a HUB to the Mikrotik.. I dont think they recognise a USB Hub.... so at max you can use only 1x 3G device....

i wan ask the routerboard inside date and time how to update daily? now i see inside the date and time all fall back to 1970 =.=.. help...

setup the ntp

hi, any guide to setup ? i refer the klseet site here.. no work ...

The only difference is that the current RouterOS will do a nslookup. You dont have to key in IP.
You may keen in the full address name instead and ROS will change it to an IP.

How is your setup coming along?

I have been using it at my new apartment for the last 2 days with a USB 3G dongle connected to the RB751G... no issues.. if you have any issues, just PM me directly.

Thanks bro,

Still dun have time to try it out,

Using Asus RT N-16 now.

I will PM you when the need arise.

Asus N16 is their top end router... should be able to do all that you need, including sharing using the 3G dongle...

The N16 can QOS and bandwidth control right...

The highest spec that I have is only the N13U....

just need some advise here.. I realized that the MTU for my interfaces are 1594 and 1598 instead of the usual 1492.. is this correct ?



Reason I'm asking is I have just recently set up a site to site IPSec connection. Both sites are on VIP20 but one site is on pfsense. The maximum throughput I could reach on average is 6Mbps, far away from the link capacity. Previously I was on OpenVPN solution and was able to max out the capacity, but due to requirements I have to move away from it.

I have also tried changing the encryption algorithm from 3DES to BlowFish and also AES which did not help much as well.. hence I'm wondering could it be due to MTU settings on my interfaces

You on software or hardware encryption?

I also had another setup, and seem to peak at 6~7Mbps too... but for their setup, the bandwidth is sufficient.... however the latency is not acceptable....

Thats was L2 MTU, for MTU you will notice it's 1500, you can change the MTU to 1492 for your PPPoE interface but I believe the improvement are unnoticeable

I am having problem configuring the NAT loopback until found the solution for dynamic ip (guideline was for Fixed IP)

for Dynamic IP, what we can do is by running and schedule every 10 min, a script to update the dst-address of the hairpin nat/nat loopback

a script as simple as



Hairpin Nat is the comment of your Hairpin NAT rules

or below might work too(untested)



or just put additional line at your dyndns/dnsomatic script

Hai.. i got problem here...

i have a RB750GL connect to my unifi BTU... and Trunk both vlan500 and vlan600 to prot 5 to connect to my RB750...
but seem like my RB750 cant recieved any trunking from the RB750GL...
anyone could help.. coz i conect the RB750 with the Hypptv that use vlan600 connection...

Mind sharing some information with us such as /interface vlan print , /ip address print

Not sure how trunking will traverse past the first router. Only read about it, but never try it...

Are both units running as Routers? I don't see any problem connecting 2 of the routers together....
What are you static Routes used? DHCP server? and IP Range for each router?

I previously had issue with NAT and all. I tried the hairpin, also didn't work for me.... in the end, i just use the following version



You can read my post about it here.

Ok..the (A)RB750GL will do the unifi dialing, and trunk both VLAN ID 500 & 600 to port 5...
then from port 5 will connect to the (B)RB750...
setting for the RB750 will get VLAN500 to share with port 2 3 4, while port 5 will only share VLAN600..

any idea how can i set the (B)RB750?

I think you should test your setup, and confirm that you can access internet and IP TV on your RB750GL.

Because on my setup, only the PPPOE dialer is on VLAN 500. After that, all other ports is not on any VLAN. I didn't bother with IP TV, but the theory should be same.

An easier setup would be, Port 5 on the RB750GL set to VLAN 600. Port 2~4 is just normal, no need setup VLAN, it should just work. PPPOE dialer (port 1) on both VLAN 500 & 600.

Then you can connect your RB750 (as a switch) to any of the port 2~4 to share the internet, while you access IPTV from the RB750GL port 5.
