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.
