I am able to telnet from one region to another on 7000 port without issues. (I get the expected Connected to .....Escape character is '^]'.)
Also I am able to execute cassandra client on 9160 port from one region to another without issues (this is when I run cassandra separately on each region without forming a cluster). So I think the ports 7000 and 9160 are not the issue.
