I have a Sophos XG 85 v17 with a site-to-site vpn running to a Ubiquiti UDM Pro. The tunnel is working great despite DNS not resolving from either end through the tunnel. The XG subnet is 10.10.10.0/24 and the Ubiquiti subnet is 10.0.0.0/24. I can ping in both directions just fine but I cannot ping any DNS on the opposite side of the tunnel. The only way I have been able to accomplish it is by adding a record to the local hosts file on the windows machines and that is just not the way to accomplish this. So does anyone know how to actually accomplish this? I've tried adding a DNS host record on my Sophos but that didn't work.
