When you are using class B private networks, you need to pay attention to the routing tables because routers do not handle them as any public network IP addresses.
So you need to check that there is effectively a route defined from your remote client to your server hosting GlassFish.
A special case to pay attention is when your server has two or more network cards. Is it your case ?
Can you also try "netstat -a -f inet" please ?
Your netstat command has displayed a IPv6-like result. This is just to be sure it is effectively listening on a IPv4 network for this particular port.
Just checking the network basics ...
