ipsec over multiple uplinks

Hi,

we have two internet connections running as balanced uplinks.

Connecting ipsec tunnel to the first uplink works fine.
Connecting to the second uplink fail. It looks like the second uplink doesn't answer the incoming ipsec packets.

In the tunnel config is "uplink interfaces" configured for the local interface.

Has anyone an idea whats wrong?

Thanks

  • What device is used as the other endpoint of the IPsec tunnel?  If it's a UTM, then the Remote Gateway needs to use an Availability Group with the IP of the uplink that is bound to IPsec with an Uplink Balancing rule.

  • Hi,

    the other Endpoint is a bintec Router. 

    I have tested a bit more and when I configure a second VPN connection with the second uplink as interface I can connect with no problems.

    In the ipsec log I get a error "ipsec starter[5161]: no default route - cannot cope with %defaultroute!!!" everytime the ipsec service reloads its config.

    Any idea?

  • Bjoern,

    Did you ever get this to work? I'm having this exact same issue and my post in a  very similar thread never got any response.
