Solved: Router with 2 interface

willemvwyk · ‎10-08-2008

Hello

I would like to confirm if the following scenario is possible?

I have a Cisco 2821 router. It has 2 interfaces. The first interface (GE 0/0) connects to the internet and NAT'ing is performed on the interface. This interface allows for the office employees to have internet access.

The second interface (GE 0/1) on the same Cisco 2821 connects the same office employees to a 10.230.0.0/16 WAN.

Is this possible? And what gotchas are there that I should be looking out for?

Many Thanks

100% possible

what u need is to make correct routing

lets say ur remote site over the WAN has network as 192.168.1.0/24

and u dont use any dynamic routing with ur remote site

u need first static route point to ur remote site through the WAN and lets say the remote router over the WAN is 10.230.0.1/16

ip route 192.168.1.0 255.255.255.0 10.230.0.1

now u need a defualt static route for internet like;

ip route 0.0.0.0 0.0.0.0 Ge0/0

or

ip route 0.0.0.0 0.0.0.0 [next hop IP for internet]

good luck
