Setting fixed ip/p.c keeps swapping it's ip with laptop? 1

[sunny3]

--------------------------------------------------------------------------------

Hi...Could someone please help...

I use bit torrent...and have enabled port forwarding on my belkin router have set it for both ip adresses,I get the green light on bit tornado and all is good...

The problem is I have a tower p.c and a laptop...when both machines are being used, sometimes the pc takes the ip address from the laptop and vice versa...

the result being the ports which I had forwarded do not coresspond to the ip address to which I had set them...

So I have to keep going into the router settings quite often and re-setting them up..using ip config to see what the current ip address is on the pc/laptop...?

Can I give the pc and laptop their own fixed ip addresses...?

Could someone please talk me through it....?

Thanks.

You need to use static, not DHCP dynamic, IP addresses on both computers.

The default DHCP scope for Belkin routers is 192.168.2.2 through 192.168.2.100. So, pick an ip outside that range for both desktop and laptop; e.g.
Desktop 192.168.2.101
Laptop 192.168.2.102
For both:
Subnet Mask: 255.255.255.0
Gateway: 192.168.2.1
DNS Servers: 192.168.2.1

See, for instructions:

Next,it would be advisable to pick two different, non-overlapping sets of port addresses for BitTorrent. Configure the BitTorrent client appropriately on Desktop and then laptop.

Now create two new "Virtual Servers" in the router setup. Use the static IP address above, and the unique non-conflicting Torrent port ranges:

Thanks for the help Bcastner...

Very helpful info...and easy to understand...appreciated.

Couple of other questions...

Do I need to change any of the settings in the router..?

Or do I just need to enter the relative info in "Tcp/Ip settings"...?

Do I leave "alternate Dns server" field blank...?

Thanks

Q1: Do I need to change any of the settings in the router..?
A1: Just the two new Virtual Server entries as explained above.

Q2: Do I leave "alternate Dns server" field blank...?
A2: Yes. The router acts as a DNS proxy server.

Only one more question...

I've read elswhere ...(

http://www.portforward.com/networking/static-xp.htm)

that the info on /cmd... ipconfig/all

ie the dns servers it reports there, are the ones that have to be input on the Tcp/Ip settings section...?

As opposed to the router ip ie 192.168.2.1

When/why would the above need to be done...?

Ps I have carried out the settings you advised and all is good.

You have a valid DNS proxy server at 192.168.2.1, which will adapt when your ISP changes the addresses of its DNS servers.

I see no valid purpose in hardcoding DNS servers in this instance. Use the DNS proxy service of the router.

Thank you very much for all your assistance.
