I have a RV082 that has an issue keeping an IPSEC Gateway to Gateway VPN running from itself to our ASA 5510.
At 8 hours of connectivity (I can almost set a clock to it) the Tunnel will say it is connected on the RV082 but on the ASA 5510 the tunnel is not up.
If I click on disconnect on the RV082 under the VPN Summary page things will come back up. from the ASA 5510 side there is nothing I can do to get things back (ping inside "vpn network" or even trying to make a connection to a networked VPN machine).
To make things more complicated I have another VPN on the RV082 to a PIX 506e that works with no issues. I also have another RV082 at another location with the same settings that keeps its tunnel with the ASA 5510 with out any issue.
Some things I have tried to try and fix the issue are:
I upgrade the firmware on the Rv082 V3 from 126.96.36.199-tm (what it was shipped with) to 4.1.1.01-sp) - This seemed to have no effect.
on the RV082 I have changed the MTU from automatic to 1428 and 1452 - all this does is make the connection to the PIX 506e unstable like it is for the ASA 5510 I have changed this back to automatic.
since the time of stability seems to be 8 hours I have changed the "Phase 1 SA life time" and "Phase 2 SA life time" to 28800 both at the same time and individually - This seemed to have no effect.
The current configuration on the RV082 are:
Local security gateway type: IP Only
IP address: (local ISP provided static IP address)
Local security group type: subnet
IP address: 192.168.30.0
