Cannot establish IPSEC tunnel using double pfSense inner and outer firewalls on each side
We are trying to setup an IPSEC VPN using double firewalls on both ends. We are able to properly configure using a single pfSense firewall on both ends, but are unable to get the tunnel to "Establish" when trying to pass the IPSEC protocols through a pfSense "edge/outer " router first.
Do you have a diagram of the setup? Is there inbound or outbound NAT involved or only routing? What rules do you have passing the traffic? IKEv1 or IKEv2?
Is this already fixed? I think we are having same issue. How did you fixed it?
