Hi, I have firewall in my network. Is that opening the port alone enough for communication?. I could be able to see in the log that the ip addresses of nodes are getting differed for the same domain e.g testnet-seed.bitcoin.petertodd.org. Is there any static ips through which we can connect consistently.
