IPSec Tunnel between UTM 9 and Pfsense 2.4.1

Hi Guys

 

I'd be appreciate if someone help me with this crazy (yet should be well easy) IPSec Tunnel between two FWs. I followed this dude's vlog, but i got no luck yet..

This is what I see from IPSEC VPN* log from Webadmin portal of UTM9 ...

I have other 3 active IPSec tunnels which are between other UTMs. On PFsense i have another 3 active mainly from AWS VPN.
From the pfsense this is what i see
 
 
ov 14 08:17:42 charon 11[IKE] <con8000|1055> initiating Main Mode IKE_SA con8000[1055] to 10.254.254.126

PFSense is on Connecting mode and then disconnects..

  • The 'Responder only' checkbox was not selected in the pfSense in the document you attached above.

  • Yeah tried that too, same error message i am getting... so no joy.. i believe this is something to do with UTM nat'd and somehow it can't communicate with pfsense.

  • One last thing to try.  On the 'Advanced' tab of 'IPsec', select 'VPN ID type: IP address' and use the public IP of the router in front of the UTM as the VPN ID.  Any luck with that?

    Cheers - Bob

  • Cheers Bob. If i do that then other IPSecs stops working. Anyway I guess the issue is how we set up the UTM by the look of it. I'll try your suggestion sometime and will post the result.

    Thanks
