Our company is getting ready to implement replication on a clustered environment from a dmz.
I already informed the devs that one would only need to open the ports that the sql server listens on for each instance participating in the replication.
The next question is which IPs would traffic originate to and from? I already stated that we only need the VIP(s) of the instance(s), but he was pressing me for 100% certainty. So, can you guys give me the 100% answer. :-) Many thanks!
