Why does the Linksys remote management override HTTP port forwarding?
The problem is that the Linksys router uses port 80 for remote management. On a real Linksys router, it uses port 80 on the LAN side and port 8080 on the Internet port. The current implementation of Packet Tracer 4.11 determines whether or not to allow remote management by using an ACL on the Internet port that blocks all traffic to port 80. The workaround is to enable remote management on the Linksys router. This allows traffic to port 80 into the device. NAT then translates to the IP address on the destination device and then sends it out to the destination device.
