I’m not actually familiar with IPtables any more (haven’t used it since early 2000). I don’t know if it has a special module for zoom or not. I was just talking about generic UDP keep-state. doing quick googling, i woudl guess you would want something like iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT but for outbound instead of inbound. You may or may not wish to make it more specific to UDP. I would expect as a general rule you would want something similar to keep-state for your TCP connections too.
