Steve,

I have two laptops sharing the same Linksys wireless router (WRT54G), which
is connected to my Road Runner cable modem. I have XP Pro SP2 on both
systems (fully patched w/ Microsoft security updates).

One laptop uses the wireless connection (WPA enabled) and the other laptop
uses a wired (RJ45) connection to router.

I noticed today that it seems the laptop with wireless connection is
displaying "Internet Gateway..."Internet Connection" 'enabled'. I don't
believe it had appeared on that laptop before. Actually I first noticed it
enabled on the wired laptop today and saw it disabled on wireless laptop, but
when I went to disable wired laptop I lost the internet connection, and
enabling it wasn't enough..I had to also enable 'internet gateway' on
wireless laptop.

If I disable 'internet gateway', even though wireless connection is still
there (connected), when I tried to use use Interent explorer ('surf') or
check email via Outlook Express neither get connected to internet. So I keep
it enabled. Sometimes "internet gateway' doesn't show up in 'Network
Connections' area. Note, Router and Modem are always on.

I also noticed that in my Norton Internet Security 2007 logs that there have
been sporadically 'unused port attack' for incoming TCP from 192.168.1.1 (my
router address) for 'Port 2869'. I also saw in log a connection to my laptop
via Port "Backdoor-g-1(1243)". When I checked norton.com for that port it
came up empty.

Does the 'Internet Gateway, Network Connection' supposed to be enabled on
both a laptop connected to the Linksys router wirelessly or wired (RJ45), and
even if typically only one laptop (generally wireless one) is online at a
time (occassionally both are online at same time)?
What about Port 2869? and Backdoor-g-1(1243)?

Thanks very much for your assistance!

The Internet Gateway is your Linksys wireless router. Don't disable
the Internet Gateway -- doing that tells your router to disconnect
itself from the Internet, which cuts off Internet access on your
computers.

The Internet Gateway depends on the Universal Plug and Play Device
Host Service and the SSDP Discovery Service. Those services use Port
2869 to look for devices on your network.

I don't know what Port 1243 is. Do you mean 10243? Microsoft's
Windows Media Connect feature uses that port.
Steve,

Thanks for your great advice!

The only device connected to my laptop is my HP printer (uses a USB port)
and sometimes I connect a Wester\n Digital Passport external hard drive
and/or a scanner to one of the other USB ports on the laptop. But most of
time only HP printer is connected to the laptop's USB port.

A few follow-up Q's:

1) What is "SSDP discovery services"?

2) What is " Universal Plug and Play Device Host Service" (is that the
printer's USB connection?)?

3) Regarding Port 2869 blocked 'attack', the message I get in Norton's log is:
"Unused port blocking has blocked communications.
Inbound TCP connection.
Remote address,local service is (192.168.1.1,2869)." Do you know what this
is and if it should be concern? Note this also happens sometimes on the
wired laptop (connected to router via RJ45).

Thanks Steve!!

Traffic on your local area network on port 2869 is OK. Don't block
it.

For a description of a Windows XP service:

1. Click Start > Run.
2. Type "services.msc" in the box and press Enter.
3. Double-click the service name and read the description.

For more detailed information, type the service name into an Internet
search engine, which will find web pages like these:
