Forward PPTP(tcp1723, GRE[proto 47]) to Two Servers from Virtual IP's

  • I want to run two pptp servers.  I have one physical WAN interface, and I want to assign it two IP addresses, then use NAT forwarding to two different PPTP server on my LAN (tcp 1723, proto 47)

    When I use proxy arp virtual IP's and do that, it works for the one server that is being forwarded from the primary interface address, but then a tcpdump on the second server indicates that it isn't receiving any GRE packets from my pfsense box, though TCP 1723 is making it fine.

    Is this a limitation of pfSense, or my misconfiguration?
