network connect fails to reconnect after Internet/WAN drop

anyone else having problems with Network Connect 8.1r1.1 and later failing to reconnect to VPN when Internet or WAN connection bounces? I have successfully recreated this in our lab and found the only way to reconnect to VPN is to reboot computer. If you do not reboot then another instance of network connect launches but never connects.

The debug logs are telling me my session got disconnected due to expired reconnect period, which seems like 60 seconds. I looked on my MAG4600 for this time period and could not find it.

Does anyone have a case number I can refer to?  I have not heard of any issues with 8.1RX.

Re: network connect fails to reconnect after Internet/WAN drop

I have had some issue on machines with Dropbox installed. Initial connection is ok but reconnections fail until I exit Dropbox. Do you have any software like that that might be causing problem at the network level?

Re: network connect fails to reconnect after Internet/WAN drop

I have a case open with my third party support vendor, fishnet. Here are the logs where i see it starts the reconnect phase and then after 60 seconds of not able to reconnect, Network Connect tears down the tunnel.

Re: network connect fails to reconnect after Internet/WAN drop



I have a case open with my third party support vendor, fishnet. Here are the logs where i see it starts the reconnect phase and then after 60 seconds of not able to reconnect, Network Connect tears down the tunnel. problem is the tunnel isnt torn down cleanly and the only way to reconnect is to reboot the machine.

Re: network connect fails to reconnect after Internet/WAN drop

Are you using split tunneling with device DNS only on the VPN tunneling profile? If yes, please try 8.1R2 or higher (preferably 8.1R4).
From the release notes for fixed issues:
If the VPN Tunneling Connection Profile is set to search device DNS only AND the role is set to use split tunneling users may not be able to reconnect after a network connectivity disruption

Re: network connect fails to reconnect after Internet/WAN drop

We are experiencing this with roles set for split tunneling and roles set for no split tunneling. Our dns setting is Search the device's DNS servers first, then client.

Re: network connect fails to reconnect after Internet/WAN drop

we are on 8.1r3.2 and 8.1r4 releases. we were on 8.0r6 and did NOT have this issue. This is only happening to our Network Connect client users. Our Pulse users are working just fine.
