Replication via Domain name instead of IP address

[asifjamal]

Hello,
I have two Terastations TS-wx2.0, one at home another at office, have setup test replication and it works fine over internet, now as the test replication worked over internet i would like to go ahead and setup real replication, my data size is 100gb for first replication after that it will be 20mb per day, so if i bring home terastation to office, setup replication locally for faster initial backup, then take it back home re configure IP address on source terastation, to new public IP, will it work, in short how to edit IP of target terastation in replication settings of source terastation,
i want to do this cos dont want to do initial replication (100gb) over internet, cos it will very slow because of slwo internet upload (only1mbps),

OR can i use domain name instead of IP address, so if ip changes it will still point to right domain, Thanks

Are you not opening a VPN tunnel between the sites? Pure port forwarding of replication packets from your public facing IP to the TS will not reliably work.
