Cannot set ISP Gateway

[CAPPBC]

I need to specify my ISP Gateway as the default route.

After I type the command:

ip route 12.51.147.0 255.255.255.248 fa4

It validates fine but I cannot ping the gateway or any website. (My DNS servers are setup and correct.)

The gateway address my ISP supplied is:

Gateway: 12.51.147.217
Mask: 255.255.255.248

Was that the proper command to input?

Of course if I input:

ip route 12.51.147.217 255.255.255.248 fa4

It generates an inconsistent address and mask error.

Thank you

I would insert this command

ip route 0.0.0.0 0.0.0.0 (next hop ip address)

your 12.51.147.0/29 appears to be your LAN side ip's
What is the WAN ip addresses? That would be your gw..

Please advise how you are setup so that we can give you better advise.....

Thanks for the input. It worked but the internet is running really slow. Slower than 56K! I checked the MTU and it is set to 1500. We have bonded T's installed. I disabled the Firewall to see if that is the cause and no difference. Is there another configuration that needs to be made?

Thank you!

Post a config. I would actually set the mtu to 1492 and the mss to 1452...

When you post the config, also post the interface counters for both your t1 interfaces and ethernet interfaces.

All is well now. Thank you for your help.
