I have an issue after I created my multilink configuration

To whom it may concern:

I created a multilink for my upgraded bonded T1. I used S0/0 and s0/1 as my multilink interface. Everything works fine for all of the users except for the users that are on E1/0. Before the upgrade the E1/0 interface connected users to the WiFi subnet and that worked fine. After the multilink upgrade, I can not get E1/0 to route users to the virtual multilink interface so that they can get out to the Internet. How do I connect the WiFi interface to the virtual multilink interface? You can email me if you want.

Thanks

Are you expecting to be using public IPs through NAT?

Ie. you have 'ip nat inside' here..

But you have no corresponding 'ip nat outside' here..

If you are expecting to do NAT, then you need to do NAT translation here on your multilink interface with 'ip nat outside'..

Rich,

You should have "ip nat outside" configured on "multilink" interface, not on "physical" interface. Just think about this: you have no IP address on the s0/0 interface, How "ip nat" may work? Traffic from other Ethernet interface does not require NAT translation, so, it goes through, but traffic from fa1/0 never gets translated.

Good luck,
