Hello,
I've got a ASG320 in Toronto and and ASG220 in London UK connected via SSL VPN.
Toronto has an E10 from Allstream and London UK has a DSL connection.
The SSL VPN comes up and works for the most part, until I put significant load on it, then it drops and stays down for about 5 minutes.
To me it seems like a MTU issue, although I could be way off base. The London UK DSL interface is set with an MTU of 1492, and tun0 has a MTU of 1500. Could that be the problem?
It's a star topology with Toronto as the center, and the other SSL connections are unaffected when London UK goes down. The ASG remains available, and PPTP connections to the London UK ASG remain up. I actually PPTP into the London UK ASG, Remote Desktop to a server, then push a backup to Toronto across the SSL VPN and only the SSL vpn goes down.
All ASGs are on 7.501.
Attached is a log before and after the drop. The reset at 2009:11:21-20:36:04 is when it came back up.
Thanks,
Brian
As per http://www.wandin.net/dotclear/index.php?post/2009/01/08/OpenVPN-MTU-Size does the ASG OpenVPN config use mssfix?
