I have have Cisco 877W router which has some web servers connected behind it. The Cisco has 8 static IP addresses on its dialer interface. Port forwarding is used to access the web servers from the internet using their designated IP adddresses.
However, from the local LAN I cannot use the public IP addresses of these servers to access them. Rather I have to use the local IPs.
This is causing a problem within the server configuration. if we use an external URL, eg x.x.x.x, to access the internet facing servers from the internal network, the address is inaccessible. Most of the time, this doesn?t present a problem, but there are times when it does. Specifically, we have to set a URL within the ?server? application to enable a particular communication process with the client PC. If we set this to the external address, external PCs can use this function, whereas internal PCs can?t, while if we set it to the internal address, external PCs then can?t use the function while internal PCs can. Therefore, is there anything that can be enabled on the router to allow the external IP address to be accessible from the internal network please?
