Opening Ports

Hello,

My problem: Can see but can't access the network printer devices from
the printer vendor's admin program. Was able to prior to SP2.

All information from the vendor (Ricoh) suggests the firewall is
stopping the communication, and their resolution centers around tweaks
to the firewall. However, the firewall is turned off (this is on an
internal LAN that has a hardware firewall to go through to access the
WAN).

Ricoh tech support said the admin program uses port 3670 and I need to
open it. When I mentioned the firewall is turned off, he said that
makes no difference, I still need to open port 3670. However, he
couldn't tell me how to accomplish the task. Googling has provided
info on the firewall tweaks only.

My question is: Does SP2 close ports without the firewall being on and
if so, how do I open a desired port or ensure it is open.

Thanks for your input

Regards

Buck

Hi Buck-

XP SP2 does enable firewall settings on the network interface(s) of your
computer. These settings can be customized locally or (some of them) via
group policy in a domain environment.

Here's a link that may help out (the 'using the exceptions tab' in
particular):

Hello Tim,

Thanks for your input.

As stated, I have turned the firewall off on the machine. My
understanding is that once it's turned off, virtually all ports are
open to that machine. Therefore, I ask my original question: Does
SP2 close ports without the firewall being on and
if so, how do I open a desired port or ensure it is open with the
firewall turned off.

Regards,

Buck

Sounds like I misunderstood your scenario then.

The Microsoft network stack does not filter the inbound or outbound network
traffic if ICF is disabled.

If you are seeing this occur, you may want to capture the network traffic
using a tool like Ethereal or Netmon at the suspect machine and verify that
it is in fact arriving in good order. If you have already done so, it may
be a good idea to look and see if there is anything else in your network
"stack" (3rd party software, antivirus, drivers) that may be unintentionally
dropping packets or filtering intentionally.

Tim,

Thanks again. Will try Ethereal.
