vpn tunnel truncates some files
Posted on 2007-11-13
I recently moved from a pix 515 to an ASA5520 and have been having issues. Some issues I have solved some I have asked help for here. I currently have an issue with one of my vpn tunnels where during certain times of the day the tunnel seems to time out or reset and when this happens the files that are being copied over are truncated. There is no specific time it is totally random. This tunnel is between my main site and my off site they both have the same ISP. I have allowed traffic to go through with out nat on both firewalls. Main site firewall is an ASA 5520 and the offsite is a pix 515E. Here are some messeages from my syslog server. These are the main messages I am getting and are at different times through out the day.
