Frame relay connections behind firewall cannot access Internet while local connections can

Hello,  I recently had a problem on my network that required me to put in two new switches.  Since it was late in the day I put in two Linksys 24 port gigabit switches as that was all that was available in place of a Cisco layer three switch.  All users in the company go through this site for Internet access, but after swapping switches the branches can no longer access the Internet while everyone on the LAN can.

The other piece of the puzzle is that my network problem involved a port on my Cisco ASA.  I had to move the "inside" port from E0/1 to E0/2 as E0/1 was putting out a lot of chatter.  Aside from that change there hasn't been any configuration changes that I'm aware of and I've looked at the running configs time and again.

All other traffic from the remote branches to the main office servers (i.e. email, rdp) has been working without a problem.

Can anyone point in me in the right direction to begin troubleshooting?  My goal is to restore Internet access to all my remote offices.  Thanks.

Check the default routing on the ASA If your local people don't have a problem the ASA knows about them because it has an interface directly attached but the ASA must not know how to return traffic back to your frame network.

Thanks for the solution!  It was(!) missing an inside default route to my network.  I really appreciate the help.
