Can anyone give me guidance on best way to set up 3 synology nas units to sync between each other fast? Im not sure i have set them up right, ive set listening on all to quic://0.0.0.0:22000 and then each nas has the following under edit device/advanced quic://:22000 (they are on a vpn so all on same network). in firewall on the nas i have allowed 22000 port and the other st ports.
I notice though they change ports so when connected dont all connect with 22000, and files transfer quite slowly despite having really good speeds everywhere! Im guessing ive done something wrong!
