I have downloaded the CHX firewall and packet filtering application from their site (http://www.idrci.net
), as suggested by several experts in other threads.
Now I have it, I just cant get it to do what I want.
Here's what I have:
1 x Laptop (Win 2k Pro)
2 x Deskop (Win 2k Pro)
Speedtouch USB modem
8 Port Switch
One of the desktop's is set up to be a file/print share and gateway. The other is a SQL / MySQL database server.
Everything was working fine using Windows filesharing and internet connection sharing (Speedtouch USB ADSL via BT Openworld). Since I installed the firewall, I just cant get the browsers to work on other PC's, no matter what I seem to edit in the filters list. I did once manage to get the PC's to be able to browse the network.
How do I configure CHX to allow web and internal network trafic (auto IP addresses from internet connection sharing) from the two other computers, but stop pretty much everything else?
Once this part is up and running with no problems, I want to be able to turn on certain ports for other applications, such as MySQL, VNC, RealPlayer, IIS (possibly) etc.
I have uninstalled the firewall for now, so don't mind using a different one, if the job can be done for the same price... ie. nothing.
Obviously, I need to put some protection on to the gateway, so for a fast response I have stacked on some points.
I would like specific instructions on how to do this, as networking, just ain't my thang.
Any help greatly appreciated.
PS. I have had to remove Linux from one of the PC's in requirement of a 3 PC Windows based testing platform. The firewall was working fine with Redhat, and I will eventually return to it, so please don't suggest Linux!!
