      LAN1 & LAN2 are actually Azure VNETs.
      LAN3 is an on premise network which is connected to LAN2 via a VPN gateway.

      LAN1: 192.168.53.0/24
      LAN2: 192.168.40.0/24
      LAN3: 10.253.0.0/16

      Traffic can go between LAN1 and LAN2 (vnet peering in Azure)
      Traffic can go between LAN2 and LAN3 (via site-to-site VPN connection in Azure)

      Customer wants to be able to comunicate between LAN1 and LAN3 as well (needs to go via LAN2). Traffic initiated on either side. I'm unable to use allow gateway transit on the vnet peering since LAN1 already have a gateway for another VPN connection. So I try to use pfSense as an NVA.

      I've deployed a pfSense VM in LAN1 (pfSense1 - 192.168.54.5) and another in LAN2 (pfSense2 - 192.168.40.4).
      I've setup a static route on pfSense1 for 10.253.0.0/16 to go via pfSense2. But that obviously is not enough.
      I can ping 192.168.40.4 from LAN1
      I can ping 10.253.0.1 from LAN2
      But I cannot ping 10.253.0.1 from LAN1, either can I reach 192.168.54.5 from 10.253.0.1

      Do I need to define a return route? NAT? If so, on pfSense1 or pfSense2? Must I mix in route tables in Azure?

      Any help is appreciated.

      Best regards,
      Pål
