--Signature=_Wed__7_Jan_2004_17_29_24_+0200_zD8HOR+vsC+twjBm Content-Type: text/plain; charset=US-ASCII Content-Disposition: inline Content-Transfer-Encoding: 7bit Hi guys. I have the following setup: one FreeBSD box with a public IP, routed by a Linux machine which has the default route on another ISP than the one my FreeBSD box's IP belongs to. Shortly said, I have different up/downstream channels. The problem appears when during a TCP connection the FreeBSD machine. The 3-way handshake works smoothly, but soon the connection stalls. I tcpdump-ed it on both streams(upwards and downwards) and I see nothing but ACK's, some of them with the PUSH bit set (this is common for webservers). There's no retransmission. The packets just stop being sent from my FreeBSD machine. Eventually, the connection times out. Has anyone encountered this type of situation before ? I could paste some tcpdump output if necessary, but I thought to ask first. I only have one interface, so reverse patch checking issues don't have place here. Thanks in advance for any help. ---- If it's there, and you can see it, it's real. If it's not there, and you can see it, it's virtual. If it's there, and you can't see it, it's transparent. If it's not there, and you can't see it, you erased it. --Signature=_Wed__7_Jan_2004_17_29_24_+0200_zD8HOR+vsC+twjBm Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQE//CXUP5WtpVOrzpcRAlGDAJ9Tp/MsBsp6rJenI3TY7fmliTabfwCgktkS RUxUKYQA2LXWYKMFdUpEC2s= =Wbsw -----END PGP SIGNATURE----- --Signature=_Wed__7_Jan_2004_17_29_24_+0200_zD8HOR+vsC+twjBm--
