Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

the situation is as follows:
i am connected to a LAN via one linux gateway (suse 8), through which other pcs in my own private network are able to gain access to the "outer LAN" and, from there, to the internet as well. sad but true, at least one of these private pcs is required to have windows 2k running. this works quite fine except for the windows "network neighbourhood", where i can only see hosts on my private net but not on the one on the other side of the gateway. i have already been told here that this should be because the network neighbourhood sends broadcast messages to the net in order to locate hosts, but these packets are generally not forwarded by routers.
i tried to gather some information elsewhere, but surprisingly i couldn't find people with similar problems. i know that for example some cisco boxed routers support broadcast forwarding, so this should generally be possible with software routing as well.
now the question is: how? how do i forward broadcast packets from one interface/subnet of my router to the other?
i don't know much about that, but it seems only to be a workaround to the original problem. also, setting up a vpn might be quite oversized for a small private LAN like mine... there has to be a simple solution.
The problem is that broadcast packages are supposed to be not routed outside a subnet. Every solution that allows it is a workaround. You may try to make all your machines (if you can; security reasons etc) in one network. You can use VPN or just make a network submask diffeent. For example if you've got machines with 192.168.0.x and 192.168.1.x adresses you can change the netmask from 24 to 23.
it's not a boxed router, just a linux machine running routing software which came along with suse 8.0., so i think it should well be possible to route broadcast packets somehow.
yes, you are right with the workaround, but sadly i have no influence to the LAN i am connected to, so i can't change anything there. this LAN got public IP addresses, so i can't just give similar IPs to my other machines.
