Default route problem.

Hi mates,

I have the following problem which I need your input.

We have a 1721 with 2 Ethernet and 1 fastethernet interfaces;

e0/0 - Connects to VSAT

e1/0 - connects to Remote site through wireless through local ISP.

FE - Connects to the LAN

Is it possible to have ip nat outside cmd on both e1/0 and e0/0 interfaces and have ip nat inside command FE?

If possible, what is the implication of having both? I have running into a situation where my default route cannot be changed to e0/0 even after defining it explicitly.

Thanks in advance for your help.

Re: Default route problem.

You sure can.

The implication depends upon applications used on these links. Some apps may have problem when the IP address is translated.

Thanks for your response. I would to know if there any parameters used to select between the two interfaces (e0/0 and e1/0) for translation .

Re: Default route problem.

Can you elaborate ?

How much understanding you have regarding NAT ( grade yourself 1-10) ?

Re: Default route problem.

It would depend on the routing.
