You should call TM and ask them for guidance. I am not sure if you can do it with that router. You might need an enterprise router.

yeah did that for two days already but they say not faulty so they keep forward to sales which looks like very busy and keep giving 'please hold our reps is currently busy'. kind of fed up so tried my luck here...

The 1st static IP that you have will be the router. The rest, you can assign to your internal devices with the gateway set to the static IP of the router. That's how IP unnumbered is done with DIR-615. Assume it's the same.

did that.. but it seems all other IP are being NAT to the gateway IP so the public IP shown is the gateway IP instead of the device IP.. tried disable NAT but not working..

it seem there is some bug at the unifi D-Link DIR-850L router 2.12TM firmware release at 2019, Dahua imou Ip Camera Cloud Live Stream would Disconnect 99% of time, While LAN and Wifi Live Stream still working 100% of time, but 6 Models, 4 Brands of newer and older generation Ip Camera Cloud Live Stream would still working well 100% of time.

tried to reset and reconfig/setting manually without config backup and upload unifi D-Link DIR-850L router, bug issue still happen.

tried to Enable UPnP: ; IPv4 Multicast Streams: ; IPv6 Multicast Streams: ; Application Level Gateway (ALG) Configuration ; PPTP: ; IPSec (VPN): ; RTSP: ; SIP: ; and Multiple Port Forwarding, work a while and Cloud Disconnect again.

Enable DMZ: work but didn't spend the times to test it for how long, but DMZ work for only single device/IP.

Tested Dahua imou Ip Camera Cloud Live Stream with TP-Link Deco M4 v2 Latest Firmware 190917 , working 100% of time.

the D-Link DIR-850L international firmware doesn't have TM TR-069 and other customization, router web interface is much smoother.

i hv questions, my router DIR850L currently, if using dhcp address cannot ping outside. but if i set static ip can ping outside. current FW 2.12. do i need to downgrage to 2.10 or straight away upgrade to 2.23 ?

such issue doesnt happen to me, which firmware you want to use, you still have to boot to D-Link Router Recovery Mode to flash it, downgrade firmware is blocked. D-Link DIR-850L with newest international Firmware 2.23, router web interface is much smoother.

Me successfully flashed my "TM" DIR-850L to FW:2.11SG firmware. Cause I wanted to get rid of the @Unifi.
Thank you DLINK, and good riddance "@Unifi" SSID.
(Anyway me not using Unifi, so that's fine)

Hi! Please share the SG firmware. I want to get rid off the @unifi suffix too.

Hi, you can follow the link here:

https://www.dlink.com.sg/starhubs/dir-850l/

Then if yours is Hardware B, download the 2nd link. I flashed it and it has been working without the @unifi ssid.

Apparently there is a newer International firmware version.
I haven't tried but ived used this SG version for weeks so far no issue.

Thank you, but I cannot open that link. Because Malaysian IP I guess??

I am on unifi ip 219.95.24.xxx , able to open his link

Aiks. I have no issue here. I tried on my Yoodo, no problem.

Please pm me the zip file. For some odd reason I cannot open dlink.com.my or dlink.com.sg. But dlink.com can..

Alternatively you can either use a VPN , or use your handphone hotspot and connect to your PC.
Because even me and socratesman have no issues loading the DLINK Page.

This is really odd.

What's your current version?

I had this version lying around. Can remove @unifi without change firmware using mobile.
Model Name: DIR-850L
Hardware Version: B1
Firmware Version: 2.12TM

Can we go straight from 2.12TM to latest Intl firmware?
Besides the @unifi nonsense, also wanna get rid of this TR069

TM itchy hand too proactive & activate 5Ghz ssid without my consent, and inform via sms afterwards:

RM0 RM0 unifi:Connect to your newly available 5Ghz WiFi connection using the temporary password ******.Visit i.unifi.my/WiFi1 to change your password

and i believe this was accomplished over TR069

Sorry to reply to your post after like 2 years later.
I faced this same issue. Flashed my firmware to the newer 2.11SG (Non UNIFI firmware), was working fine until then yesterday, did a hard reset , and I really couldnt login with the correct admin password

So after googling, I found out that need to go into Recovery Mode:
So here is how to do it:

1) Off your router.
2) Use a paper clip or small screwdriver, press and hold the Reset button first .
3) Power on while holding on the reset button.
4) Use a lan cable, set to static IP (any IP address) in Windows LAN first.
5) Goto the router page and upload the original firmware (mine was originally TM, so I tried back TM firmware) . Old version also can.
6) After flashing the firmware, then restart the router. It will work again

Original source: https://openwrt.org/docs/guide-user/install...nk_recovery_gui

Update on this:
Yesterday all a sudden the DHCP server, stop giving out IP address to a few of Android devices.
Windows is fine though.

So what happens is that I did a factory reset, thinking the DHCP might had corrupted or something.

Thats where more hell breaks loose.
Whereby not only it default back to the WIFI name, but primarily, as wayne experienced, cant even login even with the correct admin password.
Even no matter how you hard reset or even do "recovery mode" (different than upload recovery firmware), it will not budge.
Spent several hours finding and fixing the problem.

Thats where I had no choice but to do firmware recovery back to its original TM DLINK Firmware. Then only can login back. Can refer back to my earlier posting how I did it.

Few things I've learned:
1) Somehow non original firmware other than TM's firmware cause it to misbehave at the login part.
2) If you backup your settings in other versions of firmware, and restore, it will also screw up. This is what happened when this morning I tried to restore back my settings, which was from 2.11SG firmware, then again "admin password failure" happened again.
3) Yes you can upgrade the firmware later, but if shit happens, you have to flash back the original firmware. Using only LAN cable.

Short answer yes. This is the extract from DLINK


Source: http://support.dlink.com.au/download/downl...roduct=DIR-850L

I havent tried the latest firmware, but even the Aus 2.1 onwards has removed TR069 and has QOS Bandwidth limit feature

But as I mentioned in my earlier post, after update latest Intl' firmware do not perform any factory reset.
