ASA 5520 to ISA2004 VPN Issue

[chrisbicm]

Hello,

I just set up 2 ASA 5520s at my offsite location in an Active/Standby configuration. For some reason anytime that we RDP, use Explorer or SQL Enterprise Manager to connect to our offsite location via VPN the connection intermittantly freezes. All we have to do is reconnect and things are ok again but for some reason this happens every few minutes. HTTP Request go through the VPN fine, but anything else tends to close the tunnel.

We previously had a PIX Firewall in place of the ASAs with the same VPN configuration and everything worked fine. Has anyone run into this problem? Or is there a major difference between the ASA and PIX that I have overlooked??

Thanks in advance,

Chris

" Because of a protocol error detected at the client, the session will be disconnected.

Please try connecting to the remote computer again"
