Thank you for reply phil.davis,
I have attached diagrams of the system that I'm trying to build up: two pfSense configuration works, one pfSense not works.
PFS POS has two WAN interfaces (WAN1, WAN2) in failover group and two VPN connections (VPNPRY, VPNBCK) to headquarter office.
The PC has "PFS POS" as default gateway and must use it for internet navigation and for communication with HQ Server (via VPN); VPN routing is managed by Quagga OSPF and I need to have VPNPRY on WAN1 and VPNBCK on WAN2.
