Thank you Alloc,
Wow. I feel like an idiot. I had a server that was not working (which has been blown away many iterations ago), and my quick test since this was not working was to check via telnet. On connecting 7dtd direct to the IP of the server, I do see it is working correctly. Many apologies for overlooking this basic networking principle.
Doesn't seem to be said enough in this forum, but thank you for you time and effort allowing us to run these servers! And thank you for the quick support within this forum!
