I've got an exsi 5.5 box that has a redhat 6.5 guest and a win7 guest. The guest nics are connected on a vsphere standard switch. There is no connection from the vswitch to an outside physical nic.

I can ping between the two boxes, each way.

I can successfully psping redhat:22 from the win7 box.

I can successfully tcping win7:139 from the redhat box.

All firewalls are down on both boxes.

I cannot connect from the win7 box to redhat:8003, either via psping redhat:8003, nor telnet redhat 8003, nor by the application client itself.

sudo netstat -patn | grep 8003 on the redhat box shows that it's listening on 0.0.0.0.

Any thoughts? suggestions?
