    @viragomann if you're referring to me replacing the networks in the text above, I replaced all networks, both public and private so not exposing any part of the infrastructure.

      @Matt_Sharpe
      I see. But without the info about which networks should be routed in IPSec, troubleshooting is not possible.

        @viragomann OK, allow me to simply exclude the WAN addresses. I will substitute the ranges from the logs to match this forum post:

        172.16.100.1 > IPsec tunnel > 172.16.200.253 (NATs to) 172.16.210.253

              @Matt_Sharpe said in IPSec DNAT not working:

              Jan 16 14:40:07 charon 75651 12[CFG] remote_ts = 172.16.200.0/24|/0
              Jan 16 14:40:07 charon 75651 12[CFG] local_ts = 172.16.200.0/24|/0

              Did you replace one of these wrongly?
              Remote and local network cannot be the same.

                  Check your tunnel settings. Both local network or BINAT network must not overlap the remote network.

                    @viragomann The VTI tunnel is set with a random/unique IP subnet we used for the VTI routing on both sides:

                          No, the one doing NAT.
                          But obviously you've deleted it already. So do you still see these log entries?

                            @viragomann the other tunnel has been removed, as it impacts the live IPsec when enabled. If we tweak it to include the ranges in this forum post:

                            172.16.100.1 > IPsec tunnel > 172.16.200.253 (NATs to) 172.16.210.253

                              This looks well for what you try to achieve.

                              And I cannot find a hint for the disconnection of the other tunnel in the log.
                              But maybe there is an issue if you route the remote subnet over the VTI and also state it in the policy-based tunnel as remote network.

                                @viragomann is there any other way we can achieve this? With native NAT rather than a profile on the IPSEC?

                                  I reread your intention. If your only aim is to access 172.16.210.253 from the remote site via RDP, it should also work with a simple NAT rule. You can add the rule to IPSec on pfSense like this:
                                  interface: IPSec
                                  source: may be limited to the remote network
                                  destination: 172.16.200.253
                                  redirect target: 172.16.210.253

                                  You can also limit it to RDP by stating
                                  protocol: TCP/UDP
                                  dest. and target port: RDP

                                  It should also be possible to add this rule to the VTI IPSec interface instead.

                                  If packets are coming in on IPSec interfaces addressed to the destination IP pfSense will redirect them to the target. The source IP in response packets will be translated back to the origin destination address due to the state table entry.
                                  However, access in the other direction would not work this way, even not with NAT 1:1 or outbound NAT.

                                  "Any" for interface as you mentioned above is not available in pfSense, however, you can create interface groups and apply rules to them. So the rules will be applied to all member interfaces of the group.

                                      @Matt_Sharpe found a deny in the logs from target NAT to source range IP. (Changed to our masked IPs in this forum post)

                                      I do not have ANY deny rules set in IPsec interface, so why is it blocked??

                                          Obviously pfSense has no proper state for the response. Search for it in Diagnostic > States.

                                          Is the RDP server on a remote site or is local?

                                          How do we create interface groups?
                                          Interfaces > Interface Groups

                                          I assume, you won't use a group rule for this case?
