Hi, I'm trying to link two networks with user ppp / isdn line. I've two networks network A 192.168.0 (my client) network B 192.168.2 (my network) I established a ppp link trough 192.168.3.1 (my side) and 192.168.3.2 (the client side) On the client side, I'm using "ppp -auto mysite" and "ppp -direct" on my side and ppp. when the client wants to establish a connection, ppp works fine. I'm able to use ping -f on both sides. It seems that all udp clients works fine. but when I want to use a tcp connection (for example telnet) It takes more than one minute to get an answer. In fact it seems that each time each time an application has to send a lot of data the tcp connection hangs. even with the tcp extension disabled. I can reproduce the problem with tcpblast. it hangs each time. however ping even with a large packet always works fine. (7000 packet with 0% packet lost) I checked with tcpdump -i tun0 without any other connection to the client side. It took more than one minute for a telnet connection to acces the client side. without any packet transmited to the tun0 interface. The client side is running FreeBSD 2.1.5-RELEASE. Do you have any clue ? In the mean time, I'm downloading the last release of FreeBSD with user ppp on a diallup Internet access (without any problem) Thanks for your help -- Didier Derny didier@omniset.com
