<div class="jive-rendered-content"><p>I'm really stuck on this one.  I can successfully run my webstart swing application which makes EJB 3.0 calls to my JBoss 5.1.0 server when I'm on the local network, but not when I'm outside.  In that case, I get timeouts and "Could not obtain connection to any of these urls: pf.servername.org:1099".  Full exception is toward the bottom.  Firewall is off.  All appropriate ports are forwarded.</p><p style="min-height: 8pt;
