Static Route Change

Hi,

I have an Internet router that I'm changing from a multilink T1 connection to a 20mb Ethernet connect.  Provider handed me Ethernet and IP configuration. I configured the G0/1 interface and brought it up.  Once I change the default route as follows:

no ip route 0.0.0.0 0.0.0.0 x.x.x.x <-- old IP address (t1)

ip route 0.0.0.0 0.0.0.0 x.x.x.x <-- new IP address (Ethernet)

From router I can ping outside address' and resolve with DNS.  But from my network I cannot.  I try nslook up and my internal DNS servers timeout becasue thay can't get to the external DNS farwarders.  I can't ping the forwarders. So I can't get to the ouside.  It appears to me the router is dropping my packets. Should I have cleared the routing table and arp table?

Current;y I'm back to the T1's becasue it is production hours, I can try some suggestions tonight.

What could be wrong?

Thanks

Hi,

You'll have to change the dynamic PAT(NAT overload config accordingly).

Re: Static Route Change

Depends on if he uses PAT overload with interface or ip address reference.

Re: Static Route Change

All replies where helpfull, but I knew shortly after posting that what I had forgotten was that my providor needed to migrate my public address range to the new circuit.  The config on my end was fine.  Once I had them move my block everything was OK.
