We had a similar experience when we changed our upstream provider. We
would get a little bit of data from NT web servers but no problem from
Linux servers. And telnetting to the ports of servers from our Cisco
routers would work fine but not from our Linux machine or Win95 clients.
The clue came when windows 3.1 users running Trumpet winsock with small
tcpMSS sizes had NO problems. The problem was caused by the upstream
provider's Ascend Max's sending a slightly larger packet size than it
should have. Their Tech's and Acend's tech's knew about it and after going
through days of getting duck shoved around and top tech was put on the
case and applied the patch to their Ascend max which fixed it. I'll point
out it was only a problem while doing 2 BRI bonding (128k)(or more
probably) that the problem shows up.

Maybe this is you problem, maybe not, but it was interesting.
