On the system where Guacamole is running can you verify that you can make
the SSH and/or RDP connections from there to the destination hosts?  It
looks to me like the Guacamole client<->guacd traffic is happening, but for
some reason it cannot make the connection out from guacd to the other hosts. 
I'm also not real familiar with FreeBSD, so I'm not sure if there's any sort
of Discretionary Access Control system or application firewall (like SELinux
or AppArmor for Linux) that runs that would block outbound traffic by
default?

If I get a chance I'll try to spin up a FreeBSD VM and see if I can
replicate it or if I can get it to work.
