at our company we've bought a Cisco 876 Router with the Enterprise Feature Set.
Now I have to configure the System.
I would like to do the following:
Our Carrier has assignes us a transfer net for routing and a network for our router. In this Network for the router are official IP Adresses included, they should be usable via ports 2-4 on the router, port 1 should be a port which is directly attached to the internal network. This port should have an external ip address and a VPN & NAT Server on it so external users can connect via VPN and the internal network can connect to the external.
Any suggestions for this configuration.
