Remap Destination IP address through IPSEC Tunnel



  • Good afternoon,

    I am not sure what I want to do is possible, but I am trying to do this without having to try and get the vendor on the other side of the IPSEC tunnel to change anything as they are impossible to work with and take months to make little changes.

    I have a VPN tunnel built between a host in my environment (192.168.10.204) and a host on their side (10.10.75.62), this tunnel is used to allow data to be sent to the host on my side (192.168.10.204) on port 17511.  The interface on my side that receives this data has been moved from the original host (192.168.10.204) to a new host (192.168.10.207).

    Is it possible via some type or NAT rule to be able to redirect the incoming traffic over the VPN tunnel to 192.168.10.207 without having to get the other vendor involved to make changes on their end?

    Thank you.
