VPN sessions are disconnecting very often through Cisco ASA Firewall

[Ramu Ch]

Hi Team,

while traversing through Cicso ASA Firewall 5520,VPN sessions are disconnecting.

In Accelissts for VPN-Outbound traffic from LAN to Client VPN ,we have allowed all Ports.

Is there any inspection Rules are cause for this issue.

In ASA Firewall,presently the inspection rules are

policy-map global_policy
class inspection_default
  inspect dns preset_dns_map
  inspect ftp
  inspect h323 h225
  inspect h323 ras
  inspect netbios
  inspect rsh
  inspect rtsp
  inspect skinny 
  inspect sqlnet
  inspect sunrpc
  inspect tftp
  inspect sip 
  inspect xdmcp
  inspect pptp

Kindly suggest

Regards

Ramu

the best thing you can do is check the logs or set captures if the traffic is passing through the ASA so that you can verify what is the cause. It could be that one end of the connection is closing the session, it could be the ASA or it could be something else.

Captures will also help.
