I'm using iptables as an inbound/outbound firewall. I originally set it up to allow outgoing requests to the session server, but the IPs keep changing! I also had a similar problem with BuildTools downloading the vanilla minecraft server jar. Is there a way to set iptables by hostname so it works even though the IP changes? (This is in BungeeCord Help because it is a BungeeCord server that is failing to connect.) Thanks!!
