port forwarding

[Ashok S.]

Hi,
I have a modem router with nat. the nat is sue and full feature. I have
currently set it as sua. I have to forward a udp port. for this i have to
indicate the internal IP. Now I have 2 comps on the network and router dhcp
assisns IP to both computer automatically. So IP on my comp changes
depending upon which comp is connected first. The LAN IP is 192.168.1.1 and
my comp IP is either 192.168.1.33 or 192.168.1.34 . What IP address I should
indicate as my internal IP to forward the port?
or i need to setup full feature nat? Then which one in full nat - one2one,
1tomany, many to may or server? I need that port open only on my computer.
Thanks.

You need to set up the pc with a static ip address which is outside
the pool of the dhcp server but still on the same network.

When you do that you will also have to manually enter nameserver
information in the tcp/ip settings

Well, my what if my ISp doesn't offers a static IP? and then I really don't
want to pay for a static IP. I am typa in a village.
There should be a workaround.

I think James was saying that you need to set up one of your LAN computers
with a static Private IP so that the port forwarding always goes to the
intended PC on your private network. His advice I believe has nothing to do
with whether or not your ISP offers static IP addresses.

yes, thats exactly what I am looking for. But I am not quite sure how to do
it. Its also called fixed Ip, if I get it right.
Any help on this or any sites that will help me?

[Ashok S.]

ok, I got it. I was actually assigning a lower IP number and not getting it.
Anyway, its first time sometime.
Thanks everyone.
