Question

I have a rut240 router with the RUT2XX_R_00.01.07 firmware and have enabled remote http and remote https in the administrator > access settings.

I have a static IP for my sim card and have checked with a port scan software that the ports are open.

Remote ssh works without problems but somehow I can't reach the WebUI with the WAN IP. It works fine when I plug in a ethernet cable into the lan port and use the lan IP but not with the wan IP. 

Under Firewall > Traffic Rules I can also see, that the settings Enable_SSH_WAN Enable_HTTP_WAN and Enable_HTTPS_WAN are all checked to accept input to any router IP at port 22/80/443 on this device.

I read that it could be a problem with the operator of the mobile network but I can see the open ports in a scan so that should be working fine I think.

If it matters I'm using a 1nce sim with a built in OpenVPN service and I'm connected to the router via an openvpn connection to the sim card's static vpn ip.

Hello,

try to insert iptables rule to see if firewall blocks it.

iptables -I INPUT -j ACCEPT

don't forget to remove this rule.

unfortunately that didn't work. I also tried manually opening only the http and https ports but that didn't work either.

Try to edit /etc/config/uhttpd and check main section. There should be linsten_http with 0.0.0.0:80 try to change port and do /etc/init.d/uhttpd restart.

If this configuration is ok and firewall is open it must work.

Sorry to get back to this so late but I was away from work for a bit.

I did edit the uhttpd file and tried to change the http and https ports but that didn't work. It was set to 0.0.0.0:80 and 0.0.0.0:443 and I tried changing it to port 83 and 84 (which should be unused) but that didn't work either. I could see, that the ports were open but I couldn't use them to open the webui via the vpn. It did work with the wired connection directly to my computer. I also tried changing it to port 22 because I know the port works because ssh is working but when I tried to reach the webui with a browser and "ip":22 I got an error even when trying my wired ip.

Below is the content of my uhttpd file so if you can see some errors there please let me know:
