There is a JIRA issue for this feature: JBREM-749 "BisocketServerInvoker: Make configurable the address and port of secondary server socket".  It is scheduled for the next Remoting release.

Until the fix for JBREM-749 is available, you're correct.  The motivation for the bisocket transport was to support *clients* behind a firewall.

I'm recommending, whenever possible, bisocket over multiplex.  It's faster (we don't have any statistics yet, but I'd guess at least 50% faster).  It's also, in my opinion, more reliable.  It's used by JBossMessaging, which means it's being used in production in many places.  It's relatively new, and we're still shaking out some wrinkles, but I'm not aware of any comparable use of multiplex.
