Yeah Sorry about that I was playing around and it looks like I sent
out the wrong version of the config.. :P I corrected it to 0.0.0.255.

version:
Cisco IOS Software, SOHO91 Software (SOHO91-K9OY6-M), Version 12.3(8)T3

Going to upgrade the IOS to the latest version to see if it helps. 
Dennis suggested that I turn off CEF, but it did not appear to be
running. Will let the list know how it goes after the upgrade.
