firewall/http problem with 2.4 kernel

[Edgar Denny <e.denny@ic.ac.uk>]

Hi all,

I've recently upgraded the kernel on my alpha (DP264) from a 2.2 to 2.4 
and I have the following problem:

I can't seem to get http working through my firewall. At first I
thought it was an ECN problem, but I disabled it when I built
the kernel. Also, ssh works fine through the firewall. http also works
fine when I connect to other machines behind the firewall. My i386,
which is also running a 2.4 kernel, has no problems.

Can anyone help me out with this,

Thanks,

Edgar.
