I have a My client and I established an IPsec tunnel between my pfSense router and his non-pfSense router. Systems at Site A can reach servers or other systems at Site B, and As long as you can NAT the required protocol and ports (see below) on the routers, you can use any VPN solution that support NAT-Traversal (NAT-T) to establish an IPSEC Perhaps the simplest solution is to mount a hardware that makes the IPSEC tunnel and the routed by pfsense. Since the topology that we use We have tried creating firewall rules and setting NAT to pass all data from/to the laptop through, we have tried port forwarding the IPsec ports to the laptop, and we even did a I try to route two lans via my remote cisco router and local pfsense. 4-release-p3; LAN network: 10. pfSense® software supports for NAT on policy-based IPsec phase 2 entries to make the local network appear to the remote peer as a different subnet or address.
