Hi @keving, i’d like to ask you a bit more of good will.
Maybe you now you can’t figure out why your installation is having an uncommon behaviour.
But on this side i can’t figure out your enviroment, your setup of server, why you choose some option and all the “little specialties” that lead you in this situation.
Please, be kind, try to be a bit more detailed and structured on:
-your server configuration, also with network interfaces and (possibly) subnets
-at least a part of your network setup: adapters, uplinks, ip addresses (avoiding public, if possible, for reduce footprint)
-in which part of your network layout the clients has problems to connect
-the configuration of the client that are showing issues.
It will help to arrange some guesses and checks for you to find the issue and solve the “weird” netwok
