Thanks for reading my post. I'm new to Cisco admin'ing and need some help. We currently have a T1 that comes into our offices for servers and an internet connection. Its running off a 4000 cisco series as the outside router and then a 4500 series connects that to handle the "division of labor" for our servers. We currently use a Linksys WRT54GL upgraded to DD-WRT firmware for our NAT router.
I've been asked to configure a spare 2621 to handle the job instead. It will be on the same /24 as one of our networks doing this job. I will post the configuration at the end of thise for comments/clarification. Basically, I have this router sitting on the <<masked by moderator>>0/24 network with the <<masked by moderator>>10 ip address on fastEth0. The fastEth0/1 is on our internal network, 192.168.254.0/24. We are using static routes for routing. This router will eventually be a DHCP server for our internal network, but thats another project for another day.
