Correct, I have, right now, the following:<br><br>Access01 => Load Balances to Access02,03 (and itself)<br><br>Access02,03 => Forward Connections to Access01, so that any direct connects get re-roued via the load balancer, and also to get the right session info.<br>
<br>Now, when I connect to 01, it all seems to go well, and if it load balances to itself, I get a session just fine. However, if it tried to load balance to the other 2 hosts, I basically times out. I see nothing on 02,03 in nxserver.log, but in my /var/log/secure, I can see my user getting authenticated. <br>
<br>If i connect to access02 or 03, it forwards the connection to 01, which load balances, and, once again, if it load balances to itself, works fine, but to the other 2 hosts, it just hangs (client says negotiating link parameters for a few minutes, then timesout.).<br>
<br>Any particular ports/firewall openings I need to know about? I was assuming this was all over ssh. <br><br>I feel like I'm so close, but so far away! Any help would be great! <br><br clear="all">Matthew Nicholson<br>

</div>You are AIUI mistaken<br>
<br>
You can't mix direct and load balanced connections<br>
<br>
Always connect to host0<br>
<br>
Load balance from there to<br>
<br>
host1-hostxxx<br>
<br>
<br>
At least that's what I do and it works fine - and indeed it breaks if<br>
someone 'nxs' direct to a host.<br>
<br>
It may be that host0 can also be in the list - I haven't tried as I<br>
dont want/need that<br>
<br>
At least this is my experience.<br>
