moved a working network, now it doesn't work

Our office moved from one facility to another (different cities).

We took a working lan from one site, and reconstituted it at the new site. Now it only sort of works. (BTW, all linux machines)

I have a 2611 router w/VPN module, 12.2(8r) IOS:

1) fast0/0 connects to the internet (straight up, no firewall) 2) fast0/1 connects to our internal network

interface FastEthernet0/0 ip address 64.0.0.228 255.255.255.248 ip nat outside no ip route-cache no ip mroute-cache speed auto duplex auto crypto map nolan ! interface FastEthernet0/1 ip address 192.168.25.1 255.255.255.0 ip nat inside speed auto duplex auto ! ip route 0.0.0.0 0.0.0.0 64.0.0.225

from the router console, I can ping anything I would like (yahoo google 4.2.2.1) from the internal network (192.168.25.47) I can ping 192.168.25.XXX without trouble

Output of netstat is :

Destination Gateway Genmask Flags MSS Window irtt Iface

192.168.25.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.25.1 0.0.0.0 UG 0 0 0 eth0

I cannot ping anything outside (for example 4.2.2.1) . And, anytime I try to traceroute locally (besides the router), I get very weird results:

traceroute to 192.168.25.180 (192.168.25.180), 30 hops max, 40 byte packets

1 * * * 2 * * * 3 * * * 4 * * * 5 * * * 6 192.168.25.180 1.544 ms 1.581 ms 1.564 ms

traceroute 4.2.2.1 to the internet returns nothing

traceroute to 4.2.2.1 (4.2.2.1), 30 hops max, 40 byte packets

1 ausrouter (192.168.25.1) 2.965 ms 4.437 ms 4.936 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * .... 30 * * *

I've run wireshark on this network and it doesn't appear to ever hit the router (192.168.25.1) I've done the same test on a functionally identical network (machine

192.168.35.120, router 192.168.35.1) and find that I get a TTL exceeded from 192.168.35.1 after the 4th attempt

The strangest part? This worked for a couple of days two weeks ago but someone power cycled before a write mem and so it can't be retrieved. My only recollection from those edits was that I changed the speed and duplex of the 0/0 and 0/1 (but I can't be sure)
