Hi, folks. Noob, question: I want to allow a vendor to access a piece of equipment on our LAN (192.168.100.46) through port 4000 from outside via a server in our DMZ (www.xxx.yyy.zzz). While I should know how to do this, I'm not 100% sure. Can someone help? Oh, and separately, how would I allow that access only through the vendor's ip address, if that were the way I decided to go?
