[zeromq-dev] 0MQ and Firewalls

[John McLaughlin - PTIR]

Is there a officially defined position with regards to 0MQ's ability to
work in a client/server architecture where the client might be behind a
firewall/NAT-router?  If so, where can I find this documented?

 

In this scenario, what is the support for:

1.	TCP transport REQ/REP
2.	Multi-part messages
3.	TCP transport XREQ/XREP
4.	TCP transport PUB/SUB (where server is publishing)
5.	PGM (where server is publishing)

 

My assumptions are:

1.	You can bind to a TCP socket on the server, and connect to it
with the client for all of the above (1-4).  
2.	Further, I assume #5 above, PGM (server publishing) would not
work through a firewall.

Can anyone confirm these?

 

It is easy to make some assumptions about this, and test them to
confirm, but this would not assure their continued support in later
releases.
