I've set up a cisco 877 on a home network. I had problems getting internet access from the network initially. After playing about with it, i managed to get it working.
However, there is one slight problem. The guy's whose house I installed it in has a CCTV system that can be viewed from the internet via the url http;//chitchens.dyndns.tv:88 . This resolves to the public internet address of the router. I have set up PAT to translate all tcp 88 traffic over to the CCTV unit that sits on the LAN. When the guy connects to his CCTV url externally it works fine. However, when he tries to connect to the URL from his own network then the connection fails.
I suspect it's routing or DNS related. I am not sure if I have the DNS settings right. How should I be setting DNS for the router and the local DHCP clients?
The guys DSL connection DNS is 18.104.22.168 and 22.214.171.124, the CCTV is connected to 192.168.1.72
