Hi, I need to setup firewall rules and therefore need to know who wants to talk to whom. I found in the mailinglist: "glusterd's management port is 24007/tcp (also 24008/tcp if you use rdma). Bricks (glusterfsd) use 49152 & up since 3.4.0 (24009 & up previously). (Deleted volumes do not reset this counter.) Additionally it will listen on 38465-38467/tcp for nfs, also 38468 for NLM since 3.3.0. NFS also depends on rpcbind/portmap on port 111 and 2049 since 3.4" But what ports are used by servers and what ports are used by clients? I guess: servers talk with servers on 24007 via tcp servers talk with servers on 24008 via tcp servers talk with servers on 49152-xxx via tcp clients talk with servers on 111 via tcp and udp clients talk with servers on 2049 via tcp I am unsure about: clients talk with servers on 38465-38467 via tcp clients talk with servers on 38468 via tcp Anything else I missed?
