I've run into a problem with 2.6.(8.1,9) after installing a secondary
firewall. When I try to pull data through the original firewall (mail,
http, ssh), it stops after approx. 260k. Running ethereal tells me "A
segment before the frame was lost" followed by a bunch of "This is a
TCP duplicate ack" when using ssh. All 2.4.x machines and windows
clients work fine. I built 2.4.28 and it works fine from my machine. I
also fiddled with tcp_ecn and that didn't fix it either. I don't have
any problems communicating to "local" machines. I've attached the
tcpdump output from an scp attempt. NIC is a 3Com Corporation 3c905B.
Thanks !
