I have a new R600VPN and two Netgear cable modems. The management ports of the cable modems are hard coded to the ip address of 192.168.0.100. Each are connected to a WAN port and all normal outbound and inbound traffic works as expected. The issue is access to the modem management port. If I only have one of the ports open, or create a static route to the address via one of the WAN ports, the mangement site opens and works works fine. Since I only need access to it intermitantly, this is an ok solution, but I was hoping to do better. My only idea so far is to setup up a "reverse" NAT to publish a local LAN address for the port in question. Unfortunatly I cant figure out how to do that, or how to determine if it actually would work. 

any ideas would be appreciated
