I have a scenario like in picture:
R1 has public IP and is configured as L2TP Server! R2 have just internet over nat and is configured as L2TP client! Both routers have full routing table to know each-other routes. R2 has a CCTV system connected. I can access this system from R1 LAN. Also there are some other routers connected to R1 with L2TP and have routes to go to R2, from their LAN I can access CCTV system to!
But I want to access this system from WAN side, so created a portforward role to R1 from WAN IP to CCTV system IP I can see traffic pass router but cannot access CCTV System
Any mind if it should work...
