Hello again : Please ... Thank you, Merci ..., but a condition is *don't write link's*. I know this is more difficult, but I wish to do a list "thread" that can be used by the maximum people, because, in my opinion, this question is a "hole" in the "free" Internet "documentation" (Howto & company) > Alternatively, try http://www.linux-firewall-tools.com/linux/firewall/ (oh no, please !!!) Well, Somebody -Tony maybe- said : > Do you want to write the ipchains rules youself? Or would you like to > configure them through a script like pmfirewall. I want to hear your experiences about : 1) Windows'98 side : 1.1) Client side in Windows'98: Needs the navigator any special parameter to exit ? Are the parameters the same that in the "normal" config., to navigate ? 1.2) The protocol TCP/IP needs some DNS host, wins resolution, isn't it ? Note : I remember you that I can navigate very well by IE5.0 in Windows98 In other words, Win98 is well or not ? (to be or not to be) After (slowly ...is a little bit difficult to me) this: 2) Server Linux ; ipchains : command minimum abilities ? Your turn again, please...
