Hello,
A client of mine has two sims with static IP. He called me because he wasn't able to open ports to a device, even though he got his fixed IP and was able to connect to the web.
My steps in order to fix the problem:
upgrade firmware
reset via web ui
reset with button
finally after going through, I think every setting that can affect opening ports on the router, I told him to bring a router from a different company and see if port forwarding works - it did without any issues.
I told him to bring the router to our lab.
Btw, I tried to reset the RUTX12 to boot loader menu, but I wasn't able to.
Is there anything I can do in order to troubleshoot the problem?
Thanks in advance,
Roy
