Problem with port forwarding[RT-AC68 with 378.56_2]

[emalf]

I am trying to set up remote management for the routers in local network. Hence I forward port 8801~8803 to port 80 for respective IP with TCP. But when I try to access this web management from outside, it all time out.

Is there any restrictions for forwarding WAN port to port 80 in local network ? I had try 108* 6108* still got the same result.

As for port forwarding, I had successfully forward other ports for SSH,RDP,web(not on 80). The local address is correct as I can access one of the local router working on https on 8443 but not for http on 80.

Thanks
