[AG-TECH] Problems using AG Connector

[NamGon Kim]

Dear Adam,

I am sorry about the problem.
This one-directional multicast problem is really a serious problem in
deploying AG Connector.

Until now, users under fully multicast-disconnected network can use AG
Connector.
I will try to solve this problem.

I am sorry and thank you for trying AG Connector.
