Dead Peer Detection kills IPsec after 3min

Sebastian R

Hello guys,

 

I just created first IPsec connection with my UTM.

The connection is established successfully (I can ping and transfer over vpn), but after ~3min the DeadPeerDetection kills the vpn, so it must be re-established.

If I disable DPD the connections stays connected, but after next provider-disconnect there are multiple vpn's opnened on UTM-site and nothing works, so this dont seems to be a solution.

scenario:

main-office: Sophos UTM SG115, lan: 192.168.1.253/24, wan: 172.16.0.253/24 (exposed host behind a router, cannot change this atm), is waiting for vpn-connect

branch-office: fritzbox, lan: 192.168.178.1/24, wan: jgmn6nejdu33.myfritz.net, initiating vpn-connection

 

attached is protocol: 09:30:47 -> IPsec SA established, 09:33:28 -> dead peer detected

 

hope somebody has an idea

    Hallo Sebastian and welcome to the UTM Community!

    The DPD selections must match on the endpoints.  The FritzBox admin needs to enable that in that device.  If that doesn't solve the issue, then please show us a few related lined from the IPsec log.

    Cheers - Bob
