Firewall exemptions for DR?

[alex_nice]

Im trying to set up distributed rendering using VrayRT so I can take advantage of my 4090's in both computers. It works great....but only if my firewall is turned off. If the firewall is on - It blocks the communication and wont render. Does anyone know what file/exe specifically I need to allow though the firewall for this to work correctly? I already gave firewall a pass to vray and 3dsMax.




thank you

copy that! I use glasswire to monitor the in and out connections. If I start DR rendering - I get the error "can not connect to at 20204". as soon as I turn the firewall off - all works fine. I set rules for the port 20204 to open to any connections - no luck. The strange thing is - glasswire does not report any "vray connection activity nor requests to connect during DR". So I can't really open the connection for the service. Hence the question: what program and where is it to open the firewall for?
