Hi all, I've searched the last 2 days for a solution, but found nothing. So I try it here. I've set up a "normal" HomeLAN with a Linux Gateway (SuSE 8.1) and several Windows Clients. The Linux Box has the following ethernet devices: eth0 -- 192.168.0.1/24 -- connected to LAN eth1 -- 192.168.1.100/24 -- connected to DSL Modem The sofware I use are (all shipped with SuSE): smpppd cineternet iptables SuSEfirewall2 First, the connection from the gateway and the clients (over masquerading) to the internet works fine and fast. I can dial in and out. Ok, now my problem. To dialin or out I connect to the gateway using PuTTY as ssh client. (I have configured the firewall to accept ssh --> FW_SERVICES_INT_TCP="ssh") The connect works, so I can start the dialin with #> cinternet --start Now it happens... After a few seconds my PuTTY session don't react on my input and after some more time I get a POPUP telling me: "Software caused connection abort". Then I have to wait till the dialin process has finished. Then I can start a new PuTTY session to the gateway. I think it must be the firewall who disconnects me, because if I restart the firewall without dialin in, my PuTTY session just hangs about 2 seconds. But if I am dialed in (so my ppp interface is up) and I restart the firewall, the "connection abort" error occours again. Thanks for your help. Christian
