Dear List! I'm having problems while connecting to a Juniper SRX210 firewall running JunOS 11.1R1.10. I'm using the latest stable Shrewsoft client (2.1.7) on Windows 7 (but the issue happens on Windows XP, too).
If I try to connect from a device with a public IP-address, like a mobile broadband connection (without using NAT-T), everything works perfectly, but if I connect through a NAT device (Linksys WRT54GS), the connection works only for 6-7 minutes and then it terminates with no particular reason (the error message is: "session terminated by gateway"). My home firewall runs OpenWRT 0.9 and as far as I know, it doesn't have any kind of ipsec passthrough option enabled (though it seems to be using a one-to-one translation for connections made to port udp/4500). The strange thing is that using another client (vpnc) with the same network configuration, I don't experience these strange connection drops. Filtering rules on my home firewall are pretty simple: outbound connections are not filtered, I only have a couple of rules set on the INPUT chain, but none of them uses any conflicting ports. I already tried debugging both ends, but I found nothing helpful in the logs (except some "config packet ignored" messages on the client). I already tried upgrading to the latest beta release (2.2.0-beta-1), but the issues still exists. Could you please give me a clue on how to solve this? Best Regards Gergely Kiss
