Faithd only supports TCP connections and for each TCP port a separate process needs to be started. We have experimented with adding UDP support by making a python prototype (proof of concept). We did not continue to develop a production quality C implementation due to lack of interest by the users. In addition, we modified the original faithd to relay TCP connections for any port. This simplifies its configuration dramatically. Access control is then performed using firewall filtering. However, this modified faithd requires a small patch to the kernel code (NetBSD in our case). As our patches where not accepted by the NetBSD project team, kernel patching is required to use our faithd. This does not outweigh the advantage of easier configuration, and we therefore abandoned this modified faithd too.
