Hi everyone,
I have set up a IPsec tunnel between an OPNsense firewall and a Sophos firewall using VTI.
From the OPNsense VTI interface, I can successfully ping the Sophos VTI IP and vice versa.
I have initiated a BGP session between these two interfaces, and I can see the routes being exchanged on both firewalls.
However, from a PC behind the OPNsense, I am unable to ping or run a traceroute to the Sophos LAN interface.
I have already created the necessary firewall rules to allow traffic on both sides.
Thank you in advance for your help.
Romain
