      I've seen this condition happen when the load balancer kicks in and takes a gateway offline/online.

      Wouldn't it be nice to be able to implement a more flexible redirection program that supports UDP and other neat things?

              I was looking into this, I found where are the calls to load the config for /usr/bin/nc, but I cannot find in builder tools where the binary is compiled. Is this a part of the kernel build and not a port?

                nc is included in FreeBSD, so nothing special is needed to ensure it's there.

                socat would have to be added to the buildports file and copy list for the appropriate branch/version so it would be built and included.

                    For testing you can always just "pkg_add -r socat" though. Once the code is ready to be used in pfSense we can work out the pfPorts part, that's easy. The hard part is translating all the NC bits to socat.

                        I'm not sure anyone has actually officially picked up the bounty, I was just offering tips to whoever did.

                          I am thinking about it โ€ฆ there is a lot to be done for this. To be honest with you, I now use split dns (using the forwarder in pfSense) to access the servers by URL or names. This translates the names into local addresses (even on DMZ) and works without issue for me.

                            If you use split dns, how do you get around the fact that the external port address is different than the internal port address? For example, I NAT an internal service on port 123 to external 321. The client wants to be able to connect externally (mobile device) and internally when on wifi to port 321. The DNS part I get, how about the port issue?
