Dear everyone,
Have a working VPN Site-to-Site between my OPNsense (20.7.1-amd64) and a Cisco ASA 5515-x (9.12.3), I can get through the tunnel nicely via RDP (3389) but ICMP doesn't work. I have no idea how to fix this anymore so any help is welcome.
Thank you very much for everyone's help.
Beste Regards,
Remco
