Sharing DSL with dialup modem

[jewfish]

Hi,

I am trying to share out my DSL connection so that my sister can dialup my machine and use my internet connection.

At the moment, I am using a Netcomm NB1300 4 port using NAT on an ethernet connection. The NB1300 is 192.168.1.1, my home computers NIC is 192.168.1.2 with XP's firewall enabled.

I have created in XP an incoming connection, and pooled out 192.168.1.100-104 for dialup machines.

I can dialup successfully to my XP machine, but cannot access the internet from my sisters PC, my sisters machine is being assigned 192.168.1.100 with the same gateway address. I can successfully ping 192.168.1.2, but not the NB1300 (192.168.1.1).

I have configured my sisters machine with the Swiftel DNS Server addresses.

Is the reason it's not working is because I have the firewall on the NIC thats connected to the NB1300 ?. I don't want to disable it if I don't have to (note I have not had a chance to try it without the firewall on).

Do I need to add static NAT entries etc to get it working ?.

Do I need to use ICS ?

I would like to get it going with the firewall on my NIC without using ICS.

Any ideas ?

Cheers,
Rob

You need to turn on IP forwarding somewhere in network properties and also need a default route on your PC pointing towards your NB1300.

Did you say the NB1300 has 4 ports? Why can't you use one of those ports and setup a firewall on your sisters computer?

I think that his sister is not at the same house.... so she want to dial in to his machine...

What advantages does this give over just dialing a normal isp (apart from a few $/month I have no idea)

Well then, if you can access the internet from your machine and you can access your XP computer from your sisters then the problem might be in your XP machine. If you go through the network setups, you should be able to do it through there. I swear there's an option to do this. What OS is your sister using?

You might have to use ICS though. So your computer can inform the router of the extra connection/IP address. What is your Subnetting?

Disable your firewall just to see if it connects through. If it does than play with your firewall settings.

XP has some bugs with networking anyway at times, so you might be doing things properly but XP is having a spit.

Also have you got any crap firewall programs (Norton's Internet security springs to mind) installed on either your PC or your sisters, faulty Zone alarm installs can cause problems too.

Turn off XP firewall and uninstall all other firewall programs you may have installed, you can always reinstall later, please take this as a lot of experience I have had with glitchy Zone Alarm installs on my own and customers pc's. (Norton's Internet Security sucks full stop)

I used to dial into my works server to get to works database program, I also used works 1.5m connection and got better results than me dialling into any ISP I have tried funnily enough.:confused:

Make sure you have enabled IP forwarding on YOUR dialup server.

PS: The question has to be asked -- with Swiftels ADSL SOOO cheap -- why doesn't she install it there... ;)

Or even a normal dialup ISP. Then she'd get 56k instead of 33k! Without tying up your phone line.
