CISCO ASA 5515 to UTM 9.4 (SG230) VPN Peer ID

 Our connection seems to be completing phase 1, but is failing on a matched/mismatched Pair ID. The thing is that the pair id actually matches, but the log says that it doesn't, but shows the same two words there.

I don't have access to the actual cisco box, it is with an external vendor. Here are the respective logs.

  • That looks good, so I vote for Louis' idea - use a Remote Gateway definition set to "Respond only" instead.

  • We actually tried Respond Only with no success (with Sophos support as well). I also attempted to add the peer id as a dns name in the network definition and try setting the id type to IP address, but the same errors persisted. Sophos support was able to create a working test environment with an XG, see here:

    The most noticeable difference here is the Peer ID is a FQDN. This is what led me to try adding a DNS name in the network definition, but again, it didn't work. I haven't found any FQDN in the settings.
