I tried to reply to the answers to my previous post but the system says I am not authorized to reply.... so I am sorry for the duplicate posts about this.

at the client site they are using laptops with wireless connections through Cisco wireless APs to Cisco 4402 controllers. The clients are reciving their address through DHCP scope on the 4402. Their gateway is the Cisco 506e which hands it off to the cable/dsl router.

The clients can connect through a particular WAP and recieve an IP address from the controller for that WAP and make a VPN connection to Corp asa 5520.

Then the connection drops... perhaps after 5 minutes to 30 minutes. Then no more connections from this site are possible until the 506e is rebooted.

As previously mentioned... when the 506e is removed there is no problem no matter how long the clients remain connected.

Thanks
