I need help with a basic config for a 2600 rtr that has only two eth int. I also need to restrict protocols and ports used if possible. I would like to use the rtr as a gateway connected to a T1 at int eth0/0 and the internal net at int eth0/1. Any Help please
 
correction to previous post. I need to connect the 2600 between the gateway and my network to filter internet traffic using undesired protocols and ports. I will connect 0/0 to the gateway and 0/1 to the internal. not sure how to ip the interfaces and block the unwanted traffic, allowing only very well known ports and protocols.

Thanks
 
int e0/0
ip add neg (or a static in the same subnet as the gateway...ip add x.x.x.x y.y.y.y)
no shut
int e0/1
ip add x.x.x.x y.y.y.y
no shut
access-list 101
deny tcp any 192.168.1.0 0.0.0.255 eq dns
permit ip any any

That's an example. Google for Cisco basic config examples---plenty on Cisco's site. I doubt anyone here is going to totally configure your router w/0 a fee. If your router has 10MB ethernet interfaces (2611), then you need a robust IOS other than IP Base or IP Plus code to do ip dhcp, or to run full duplex for RoAS/VLANs.
