1601 config, can someone help add what I need ?

[gman10]

Hi guys-

My question for all the Cisco gurus out there is.. I have a 1601 router setup at a school district that has NAT setup on it and the T1 port is connected to a CSU/DSU and the 10BaseT port is connecting to a nic on an NT server. This NT server used to be a software firewall box and had another nic that was setup and connecting to an Alcatel Omnicore switch.. Well, to make a long story very short.. the NT server did a blue screen and can't be revived. My colleague and I used a different NT server(the existing WINS server) which still is their WINS server and added another nic to it so I can connect to the router directly like on the other server before it crashed -essentially this is the new NT server but can't load the software firewall software because the school district can't find it! good grief.. Now for the real question.. How can I setup NAT on the 1601 router or whatever translation I need necessary in order for the school can get internet access.. at this point there are VLANS setup on these Alcatel switches and I can ping what seems to be -everything correctly.. Can someone take a look at my config and verify what I need to change/add to my config? Thanks guys ! Hope to hear from you all.. Here the config ..

** As you can see I've got NAT setup for translating my inside ip's with an outside address but I need to be able to setup an additional NAT issue in order for internet access, can this be done on this 1601 series router? Any help would be greatly appreciated!

thanks gman
