Try experimenting with the TCP MSS size in the route. I have had some
problems getting later versions of Linux (> 1.3.50) to talk to systems running
old versions of Trumpet Winsock. Changing the MSS from 1500 to 1372 fixed it
for kernels up to 2.0.25, but not the 2.1.x series.

I know that the old version of Trumpet is buggy, but the same could probably
be said for aptguides.com (perhaps their even running Windoze 3.1), the
symptoms are very similar...
