Iam new at this and was reffered here by a friend.
We have 2 groups, each with its own network, one with the 172.25.0.0 addr range and the other a 220.127.116.11 add range. We want the users on the 172.25 network to access a particlar server on the 192.168 network without investing in a firewall BUT at the same time put enough security to protect the 172 netwrk from being accessed by users on the 192 network. We want to use an idle 2621 router with 2 ethernet interfaces.
Is there a way we can make the 2621 router behave like a firewall to allow only traffic going from the 172.25 net into the 192.168 net but preventing the 192.168 from accessing the 172.25 ?

decision. To do this we require the switch to do...
