Port-forward IPSec-Traffic

  • Hi!
    We have multiple external IPs configured on our PFsense.
    We also have already multiple IPSec site-to-site tunnels up and running.
    Now I have a server on the DMZ-side, wich needs to receive IPSec-connections.
    I forwarded UDP 500,4500 and ESP to this server, set up via NAT and also via firewall rule.
    But still I'm not able to connect.
    I set up packet capture and additionally the logging on all rules, but I'm not able to find a connection attempt from my client which is online through LTE.
    What am I doing wrong?
