I have a gateway connected to a RUT240 runing on 4G. I would like to have access to the webinterface on my gateway through RMS. My gateway only has a WAN port where the RUT240 is connected through. To got access to the webinterface I have to use the AP on the gateway, and then I can connect to webinterface on 192.168.55.1.
The RUT gives the gateway the following IP 192.168.1.131. If I try add a device under remote http and enter 192.168.55.1 as IP, I'm not able to connect. How can I solve this? Do I need to enable "remote http access" under System -> Administration -> Access Control ? I have no trouble connecting using CLI and then ssh using 192.168.1.131. What is the best solution to solve this? I did read up on something called ip route?

Should I make some routing changes on my gateway or do I need to change something on my RUT240?
