I don't have any Cisco experience, but I decided to ditch my consumer grade ADSL routers and replace it with Cisco 877W. I managed to configure almost everything via SDM, so wireless works and I'm online using NAT. The bit where I got stuck is a secondary IP range - my ISP allocated me a block of 16 public ip addresses, which I use for IP cameras, VoIP phones etc... I need to configure the Cisco 877 to be aware of that and to simply route the traffic thru (no firewall) - but I'm pulling my hair out and I just don't know how to do it. Please help before I hang myself!
