There shouldn't be any firewall associated oddness, as there is none.   
However, the IDS/IPS may be to blame.  I see that the backup machine  
can't have a static IP address.  I can potentially have the security  
office white-list all connections to papio on certain ports.  What  
ports would be relevant for your issues?  Just 22 and 1194?  UDP/TCP,  
or just TCP?

Is the backup system actually having any issues, or is it just your  
client?  You'd get a pretty clear message if you were getting banned  
(if you tried to go to something via HTTP).
