What are you talking about? If you're talking about some personal FW
solution, you open the ports on a PFW solution. You forward the ports on
a hardware, appliance or a gateway software network FW solution.

Sorry about not being specific, what I am trying to do is following:
I have one WinXP laptop which connected thru internet via 3G PCMCIA
modem. and I also have one linux box in my LAN as a webserver, so
everytime my laptop connected to the internet I want people outside to
be able to see my linux webserver. I am thinking about subscribing to
dyndns.com and then do Portworwarding in my laptop firewall. Let say
people access my laptop thru mylocal.dyndns.com:80/ and it will be
redirected by my laptop firewall to my local linux webserver
192.168.1.10.

is that posible to do that? and do you guys have any recommendation
about free windows firewall with portforwarding ability?

I hope I wrote it clear.

thanks

Why don't you get a device to connect to the internet first, not your
laptop, then use that device (often called a router) to forward to your
web server all the time. You can then hang an access point off the router
and use your laptop any time you want.

Why don't you keep it simple. You should get a router or low end or used
FW appliance that does port forwarding to a specified IP/machine. As far
as you finding some kind of free FW solution that does port forwarding
on the Windows platform, I doubt that you'll find anything that's free
that's worth anything that's going to run on that laptop.

Thanks for all replies, I really appreciate it. I have my own router,
but the router does not connect to the internet directly it has to
connect to the internet thru my laptop, because I have this hsdpa 3G
PCMCIA Modem card from my office and I am traveling alot this year so
I've decided to cancel my ADSL line. Correct me if I am wrong, my
understanding is that if the router does not connect to the internet
directly it will not be able to do PortForwarding? Am I correct here?

Thanks.

If the router is connected to the laptop and the laptop is the gateway
to the Internet, the router is getting an IP from the laptop, it has its
DHCP server active, or the DHCP is not active then the router would be
just a switch it can't route, then you should be able to router traffic
to a LAN IP/machine connected on the router, if the DHCP server on the
router is active.

Really, you need to change this situation of the laptop acting as a
gateway running the Windows O/S. It's bad news. You don't have the O/S
on the laptop conditioned to face the Internet and it can be easily
attacked. You should have the router acting as the gateway, facing the
Internet protecting the LAN and all machines behind the router.
