I'm running pfSense in a KVM and a PBX server in another KVM.
I connect through a VPN to the pfSense server, all is working fine, now I can ping my pbx server "behind" it, the only issue is I get timeouts every few pings.

Normally one would blame this one the NIC, but as these are virtual NIC's and there is no problem with the host's NIC.
What could be the issue ?
