I have 3 NICs in my server and I want to lock the external access to one network… If I disable the two I don’t want it on then it will go out the correct on just fine. When the other two are enabled then it chooses the other network that I do not want it one. I know you can set what IP to listen on but there needs to be a way to set what IP to remote access from too.
Is there anyway to force it to only remote access from that one IP?
Make sure the other two NICs don’t have a gateway address configured.
By default, Plex uses the first NIC which has a valid gateway set.
(if you don’t use those additional interfaces to connect to several internet connections, that is)
