NAT-T IPSEC VPN



  • Hello,

    I need some help. All our offices have pfSense as a Firewall. We have 2 WAN on the main office (1st one PPPoE, the 2nd Static - with failover).

    IPsec VPN works with no problems when the conection on the main office pass by the PPPoE link. Today the PPPoE link went down, so the second link assumed the traffic. What happen is that I can ping all devices from both sides, but without traffic (I can't, for exemple, access share File Servers from both sides + connection via RDP).

    That second static link have a DMZ connection with the same subnet mask as the LAN on the ISP router:
    Router IP: 192.168.16.1
    Firewall DMZ: 192.168.16.2
    Main Office Lan: 192.168.0.0
    Branch LAN: 192.168.1.0

    Can someone help me to solve this?

    Thanks.
