I have a RUTX11 running latest firmware (as of 10/18/2022). I have enabled remote HTTP access and assigned the port to 8080. From a remote computer's web browser, I tried to access the RUTX11's webUI with the wan IP reported by the RUTX11 and port 8080 (e.g., xx.xx.xx.xx:8080) and I get a timeout. I get a different IP address, however, when I use whatismyipaddress.com. Using that IP address with the port (e.g., yy.yy.yy.yy:8080), I also get a timeout. I can only access the RUTX11 remotely using Teltonika's RMS interface, but I don't want to have to go that route long term since I don't want to have to generate a special code / signature to get in. I'm using T-Mobile as my LTE provider.
1) Why can't I access the router's webUI remotely? Is there some other setting that needs enabled?
2) Why is the IP address reported by the RUTX11 different than whatismyipaddress.com's IP address?
Thanks in advance.
