Question

Wake on LAN/WAN port forwarding on Cisco routers

Asked by: Jay3112

I have 3 locations connected by Frame-relay on Cisco routers (2651 and two 1751). My main office is the 2651 and ip address 192.168.10.1 LAN, my remotes are 1751 and ip address 192.168.15.1 LAN/(10.1.14.254 WAN) and 192.168.20.1 LAN/(10.1.16.254 WAN). I have a Cisco PIX firewall appliance between the WAN and the Internet and the PIX is doing all NAT. I am using the AMD magic packet utility to start computers on the LAN and it works fine, but I cannot start computers at the remote sites. I have done some reading and tried to port forward udp, but I am not doing something correctly? Please list the Cisco router commands to enable port forwarding or anything else I need to add to use magic packets on my WAN.
