Hi,
I have a cluster with more external interfaces, two interfaces are Internet peers and third external interface is connected to telecom MPLS service. I am trying do do S2S VPN setup from MPLS interface towards the remote Sophos Cyberoam device. Anyway, my tunnel is not coming UP although I checked all VPN parameters, I am suspecting it has something to do with this strange IKE behavior. Other end device is Sophos Cyberoam device and it reports error message that we are using wrong PeerID, it sees our main Internet interface address as our PeerID instead of our MPLS interface address.
