We are experiencing problems with a PIX 515e firewall V7 software. The PIX sits at our central site and handles s2s VPN's.
When a remote VPN user to send information through the PIX to a central server we receive a sporadic error:
No route to (External IP of User) from (External IP of PIX)
This is only a real problem when the user is sending a large email. When this error appears the SMTP connection terminates and doesn't attempt to reconnect. The PIX has an outside default route to a Cisco router on a fixed line.
Can anyone please HELP!
