RDP connection to a custom port with two routers on the way

[whatever61]

I have two PCs and would like to access both of them externally.

I have two routers:
1. is MODEM-ROUTER
2. a regular ROUTER

There is a connection between the LAN connection of the first goes to the INTERNET connection of the 2nd.

The first PC is connected to the MODEM-ROUTER and is using the default RDP port (3389), did the port-forwarding and all works well.

The 2nd PC is connected to the 2nd router, I configured the RDP port to be 3391, disabled firewall and I manage to connect internally, but not externally.

I configured a VIRTUAL SERVER properly to forward incoming TCP connections to port 3391 to that PC with port 3391. It still doesn't work. I am thinking that perhaps its related to the 1st MODEM-ROUTER being on the way? Should I do something there?

You need to port-forward 3391 from the first modem-router to the WAN IP of the 2nd router.
Your 2nd router WAN IP should be static and in the LAN subnet of the first router.

I don't remember actually, maybe I did it indeed 😀
Anyway, glad we cleared that out!

Thanks
