IPSEC Tunnel - Need Help
« on: October 17, 2019, 11:09:10 am »
Dear Forum,
I'm new to the Opnsense system and need a bit of help setting up an IPSEC tunnel to a customer site.
We received settings from the customer, which we have tried, but the tunnel is not established.
The logs are the following. I have also attached the configuration from both sides.
I have also carried out the steps and settings in the IPSEC Tutorial, still no tunnel.
The customer side of the tunnel is a
Hardware Version: FortiGate-1500D
Software Version: v5.6.8,build1672,190130 (GA)

Our side of the tunnel is the latest Opnsense stable version.

Thanks,
Arthur Kahwa

Hi,

did you exchange the ip numbers in the log?
Customer side uses 169.254.72.200?
That range use DHCP Clients, wenn there is a problem with the dhcp server.

regards,
Ralf

Hi Ralf,
no, I did not change any of the ip addresses in the log.
I will consult with the client, if they are using theses addreses on purpose, for some reason.

We received and followed the following plan from our partners.
Maybe this can shed more light on the situation.

Thanks,
Arthur
