Can you try this:

Fastethernet: 192.168.1.254 mask 255.255.255.0

Serial: 10.100.1.254 mask 255.255.255.252

Hi,

I assume you use 10.100.1.254 mask 255.255.0.0 for your FE. So the total available subnet you can use is 10.100.0.1 - 10.100.255.254. This is a huge subnet, I would suggest you lower down it to 255.255.255.0 if you do not require that big subnet.

As for the Serial, I assume you are using 10.101.1.254/255.255.255.0

FYI, most point-to-point link just require not more than 2 host, so please use 10.101.1.254/255.255.255.252. (other available IP is 10.101.1.253). It just my opinion.. you can still use 255.255.255.0 if you want. :-)

Note: there is a good online subnet calculator you can use --> http://www.subnet-calculator.com/

Hope it help.

Thanks.

real quick something else i discovered when i do a traceroute on the seattle location it tried to go out my other (working) T1

Hi,

1) Housotn router config.

- why access-list 100 implement in s0/1 since the acl is allow all? Are you trying to see the traffic flow ?

- you do not need "ip route 10.10.0.0 255.255.255.0 Serial0/1" because the default route will take care of it

What do you mean "you discovered traceroute on other (working) T1" ? Does it mean in seattle router have others WAN link?

Rgds,

Christopher
