[javagroups-users] JGroups TCP over WAN

[Yuval A. <yu...@to...>]

Hi All,

I was trying to configure JGroups to work with a simple application using
TCP over WAN.
The test landscape is static and simple - two servers connecting over WAN,
with various firewalls and routers along the way.

The main issue was that I couldn't find a good working example for JGroups
over TCP between static servers.
I got a mail thread going back and forth with Bela, and he helped me a lot
(Thanks!)

Without further ado, this is the final configuration I used:

Lessons learned:

   1. Make sure server names (in *bind_addr*) resolve to the proper public
   IP. For example, if you have 127.0.0.1 servername* *in your /etc/hosts,
   that's going to be a problem.
   2. Always make sure your ports are exposed on all firewalls and routers
   along the way. When in doubt, launch a client and telnet <servername>
   <port> and see if you have a connection

@Bela - thanks a bunch for all the help.
@All (especially newbies) - use this simple app and configuration if you
need a good start.

Cheers,
- Yuval
