Site to Site UTM 9 with ASA 5510

hi alltogether,

i have a sophos utm 9 on the one side and on the other i have a Cisco ASA 5510. They are connect over an IPsec tunnel with AES-256 PFS

The VPN Tunnel is working.

But after the 24h disconnect on the side of the ASA, the VPN Tunnel isn't connect anymore. In the webinterface of the UTM  i still get the message that the tunnel is connected.
I have to restart the UTM 9 and everything is working again, till i have the next 24h disconnect.

Can you please help me.

  • Have you selected DPD on the Cisco?  If so, then what happens if you use a "Respond Only" Remote Gateway definition in the UTM for the Cisco site?

    Yes, it's possible to do a full tunnel with the UTM.

    Cheers - Bob
