IPSEC WAN interface subnet unreachable

  • I have a site to site ipsec VPN up and running with my buddy but I cannot access anything on the same subnet as the WAN interface of pfsense. I have a home router netgear nighthawk which is everything in my lab gets static routed to 1.254. My lab subnets are all /24, 3.0, 4.0 and 5.0. The pfsense VM is 5.90 and has only one interface WAN (EM0). The remote site can ping all hosts in my lab on 2.0, 3.0, and 4.0 but cannot ping anything in 5.0 beside pfsense. I think this is because typically traffic is only sent to the default gateway if it is out of the subnet but in this case the destination resides on the same subnet as the pfsense vm and since pfsense is not a switch it just drops this traffic. I am wondering if there is anyway I can make this work? the default gateway for pfsense is a cisco 1900 series router.
