Linksys connectivity problem using 2.6.0-test4

[Fawad Halim <fawad@fawad.net>]

Hi,
    I'm having trouble connecting to the http based admin ports on my 
LinkSys VPN router (BEFVP41) using the 2.6.0-test4 kernel on Redhat 9. 
The connectivity works fine with 2.4.20-19.9 from Redhat as well as 
other 2.4.x kernels. With the 2.6 kernel, I can ping the machine, but 
can't connect to the http ports (80, 8080)

The VPN router is doing NAT correctly for both kernels, and connectivity 
to services other than the router itself is fine.

I am not sure where to even begin debugging this problem.
