Hi Christer,

what is this "mobile emulator", how is it realated to a firewall?
Does it do network connections and from where to where?

Hi Alex,

netbeans 4.0 is a java IDE with it''s own mobility pack. In this pack
there
is an emulator that shares your network connection for simulating a
GRPS/3G connection. Somehow running a firewall that doesn''t obstruct
any
other operations, prevents the emulator from running. It freezes. Stoping
the firewall and setting INPUT and OUTPUT to ACCEPT makes it run again.
Pretty strange if you ask me. :-) What tools should I use to debug the
operation of the emulator, so that I could create a rule that allows it to
work properly? tcpdump comes to mind.

All the best,
Christer

First of all have a look at /var/log/messages if you see some shorewall 
hits. If yes, try to verify that they are caused by your emulator. If 
you need help, post them here
If it doesn''t log anything use tcpdump or ethereal.
