Firewall

[Jon <jo...@digital-innovation.no>]

hi,
I've just started look into activeMQ (latest version). 
My 'problem' is using several brokers which are behind firewalls('clients'),
communicating to a single broker outside the firewall ('server').
The server subscriber subscribes to a separate topic on all brokers behind
the firewalls (clients), and the clients subscribers subscribe to its own
topic on the server broker.

The communication is then:
client connects to server and receives its messages and the server receives
the messages from the client...

My question is really; When the client behind firewall connects - will the
server broker need to connect to the client broker with its own connection
(to receive its messages on the client), or will it reuse the connection
created by the client ? If the first is the case i'll have problems...

-Jon

this was a feature in amq 3.x - but networks have been re-written for  
amq 4 - and this has been missed off the list. Will add it asap

Re: Firewall

Hi,
I gave it a vote.

This problem should be a quite common problem i would guess. Accessing a
broker behind firewall would simply not be done without reusing the
connection from the broker behind firewall. So if a broker outside a
firewall detects brokers inside the firewall (by the inside connecting to
the outside), it should make the broker inside the firewall available to all
other brokers on the outside-network. So if it was possible to build a
network of brokers and address them by an unique name, and let all brokers
know of everybody - i quess the problem was solved.

Since my network topology often is a mix of firewalls i have no control over
and them i have control over, i really need something like this.

Anyone who knows of a JMS project supporting this? 

-Jon

Re: Firewall

Its the 'first' case .... 'server' broker needs to connect to to the
'client' broker inside the firewall for message flow 
from 'server' to the 'client' broker.

Interestingly, I just filed a jira related to this - check out AMQ-920 and
vote if you are interested in seeing it addressed.
