 I posted the following question elsewhere, and was advised to post any future
stuff here.
Unfortunately, the link that Svyatoslav gave me didn't answer my question.
The question is specifically about ports open to the Internet when using
active sync to sync my PPCto my PC via USB.


I am running WinXPSP2 and ActiveSync 3.7.7 along with Zone Alarm Pro and a
dialup broadband Internet service.
I have no problems synching my PPC with my PC via my USB port, but am
somewhat concerned that when Active sync is running it requests, via ZA,
internet access and internet server rights. The sync will not work unless I
grant these.

ZA then indicates that ‘ApplicationLayer Gateway Service’ and ‘Connection
Manager’ are listening to a shedfull of ports including 990, 1026, 5679 and
7438. Now this is fine and dandy (I don’t care a fig) if I am not connected
to the Internet. (I assume that I am not unless I connect to my ISP even
though my modem is connected to somewhere at 1.1Mbps) but when I am, a quick
trip to grc.com confirms that the ports are open and presumably just sitting
there waiting for a friendly drive by port scanner to reveal all my secrets
to the wide world of hackers.
I am unable to find any options to switch off the Internet bit of active
sync, even though it’s obviously not needed to sync my PPC.
Can someone please shed some light on
a. Whats going on
b. How can I stop it going on

TIA Trevor

 I really don't think you have an issue. Typically firewall software assumes
the network address that your PC has defines the network it is in, such as
192.168.1.23, would put you in the 192.168.1.x network with a mask of
255.255.255.0. The ActiveSync Process sets up a second virtual network port
on the PC at 192.168.55.100 and the PPC is 192.168.55.101. It further sets
up a router function so that the internet requests that come from
192.168.55.101 are routed to the actual internet connection on the PC. A
firewall will normally see activity from 192.168.55.101 or 100 as activity
from a foreign network. You could try just setting 192.168.55.0 as a
trusted network in ZA.

Hi Alan,
Thanks for the reply.
I have disabled ethernet sync. Zone alarm still reports
Connection manager blocked from listening to ports TCP 999,1026,5679,7438
Active sync application listening to ports TCP 999,5678
PPC is syncing ok with these settings, but I am still a bit unsure whether
the ports should be open or not, and if so, is there a security risk?
GRC Shields Up now show 1026,5679,7438 in stealth
5678 closed and 999 open with the comment puprouter Unknown application for
this port.

TIA Trevor

Hi

Hmm... this is strange, port 999 is used for time syncronization 5678 is
used for the syncronization of data and finally 5679 is for sending out a
heartbeat signal.

to be honest i only thought thise ports was open if ethernet sync was
enabled? maybe it used as a part of the passthough internet conenction?
