IPSec VPN between XG and Opnsense

We have existing Cyberoam in our HQ. One of our store is using OPNsense. Currently our HQ and the branch office is connected via IPSec VPN of Cyberoam and OPNSense. Now I bought a new XG. Im trying to establish IPSec VPN between XG and OPNSense but it can't connect. I check the logs of strongswan and charon.

  • Hi ,

    Thank you for reaching out to the Community! 

    Can you show us the screenshot of the IPsec connection and the policy? 

    Thanks,

  • Hi ,

    below is the screenshot of the cyberoam which is currently running

    this is for OPNsense

    this is the XG Policy I created

    Thank you,

    Edward

    Thank you and best regards,

  • Hi ,

    Thank you for the update. 

    The configuration seems fine, except the remote and local ID are identical. 

    Can you try to change the local ID on XG and use the Port2 IP, and for the remote ID, use the peer firewall's WAN interface IP? 

    Check out the steps below to collect debug logs; you can send them to me via PM. 

    • Steps to put the strongswan service in debug:
      • SSH into the XG firewall by following this KBA: Sophos XG Firewall: How to SSH to the firewall using PuTTY utility
        • To connect using SSH, you may use any SSH client to connect to port 22 of the SFOS device.
        • Select option 5 Device Management.
        • Select option 3 Advanced Shell.
      • To put the strongswan service in debugging, type the following command: service strongswan:debug -ds nosync
        • Output
          • SFVUNL_AZ01_SFOS 18.0.3 MR-3# service strongswan:debug -ds nosync
            200 OK
      • Run the following command to check the status of the service: service -S | grep strongswan
        • Output
          • SFVUNL_AZ01_SFOS 18.0.3 MR-3# service -S | grep strongswan
            strongswan RUNNING,DEBUG
      • Note: Run the same command to remove the service from the debug.
    • To check the live logs, run the following command from Advanced Shell: tail -f /log/strongswan.log
    • The less command allows you to parse through the static log files. You can also match keywords within the logs by entering /<keyword or string>
      • less /log/strongswan.log
    • The grep command applies a search filter for the keyword within the logs.
      • grep ‘<Keyword/String>’ /log/strongswan.log 
      • You could filter logs with the tunnel name if there are multiple IPsec tunnels.

    Thanks,
