GRE tunnel and Outbound NAT return path problems

  • Hi!

    I have a pfsense box that want to connect to, from an external network, by being routed through a GRE Tunnel due to ISP configuration (pfsense WAN IP is, GRE interface IP, the ISP tunnel end And I am trying to reach an IP on its LAN (LAN IP, destination IP I'm trying to connect to, is
    Because I am connecting from outside of the GRE tunnel, pfsense sees my incoming address as 62.x.x.53.
    Trouble is, the LAN device expects to be connected to from, and so I did an Outbound NAT rule on the LAN interface that converts my incoming source IP, 62.x.x.53 IP, to
    Now naturally, is replying to, which dies in the pfsense, because it has no where to send it to (I think).

    How do I change the destination to 62.x.x.53, and route it back through the GRE tunnel?
    I would also like to be able to modify any new traffic from, going to, to 62.x.x.53.
    Ive tried port forwarding from 10.11.055 to 62.x.x.53, setting outbound nat on the gre interface (which converts the source address to any address of my choosing), but nothing seems to work.
    Please what am I doing wrong, and how can I fix it?

    Thanks in advance!
