as long as you can see the packet hitting the FW in the first place then its probably:

a) rules on your firewall
b) firewall on laptop

New question now :lol:

I want to set up port forwarding. Do I need to do anything on the router?

I've tried adding a rule to the firewall to forward anything coming in on a particular port to be forwarded to the same port on the laptop but doesn't seem to make any difference........is that because its coming via the router and being blocked?

Fucking get in. Spot on guys, works a treat :D

All I did was manually set the IP and DNS on the laptop as suggested and worked first time. Magic, thanks everyone :)

firestarter does both - internally routes the internet from one port to another and acts as a firewall. I think the only settings it has are to allow all connections from the laptop ip, and allow all network users access via samba and the media server i have setup.

Server is running a firewall which also forwards the dial-up internet out through the ethernet port.

On ubuntu?

Just used the wizard in firestarter to organise re-routing the internet and left it at that.

If you mean the firewall on the router i haven't touched it.......

how about the firewall, have you set that up properly? Need to see the ruleset TBH

Oh, and i'm using firestarter on ubuntu to deal with ip forwarding so i think that aspect should be covered.

ok. Thats going to give me a few things to try tonight - server is at home but i'm at work. As i say, i tried it with the gateway set to the routers ip rather than the server so that is probably what i did wrong.

Go to a command prompt and do an IPCONFIG /ALL on your laptop (if its windows) and see what you've got as your DNS server.

Should i set up the dns on the laptop as well or leave that as automatic?

Set the DNS on the laptop to your ISP's DNS server addresses

OK I've reread it.

Basically the machines need a Default Gateway of the Ubuntu server to access the inteernet, also make sure the Ubuntu server is configured for IP Forwarding otherwise it will not forward your packets to the Internet.

Also make sure this isnt a DNS issue, by running a command like so on your laptop:

ping -t 212.159.13.49

hopefully you'll get replies, if so that means you just need to configure DNS and you're aaway.

How are you trying to access the server, by IP or DNS name.

You should be able to see it by IP regardless of your gateway settings as its on the same sub-net..

Try to set the default gateway on the laptop to the server IP address

Forgot to say, the laptop and server are able to communicate to share files and I also have a media server up and running on it which the PS3 can connect to no problem.

The only issue is sharing the internet.

Having a bit of trouble with my unusual home network setup.

I have the following:

Belkin wireless router is running DHCP and assigning IPs as necessary.
Ubuntu server with mobile broadband (effectively dial-up) wired to router via ethernet.
Server is running a firewall which also forwards the dial-up internet out through the ethernet port.

Vista laptop wants to connect to the network and use the internet from the server, but I can't work out how to do it :(

Tried a static IP and DNS on the laptop and not even sure if I'm putting in the right information and so (as I expected) it didn't connect.

At the moment the router is 192.168.2.1, server has been automatically assigned 192.168.2.8 and laptop is 192.168.2.4

Anyone help or point me to a decent tutorial? Been searching for ages but can't figure it out :(
