I am just getting started with linux IPchains and I could use some basic
information. I have read all the howtos that I can find but I have a
question as it relates to my network. I am running a local network of
win and os2 machines. I have a Linux internet server that will host my
web site. I am connected to the internet thru a dsl modem
The network is setup as follows
network workstations 185.68.1.2/24
Server network card 185.68.1.1
Internet network card 198.14.14.1
Internet gateway 198.14.14.12
I want to connect the system so that the network stations can access the
internet so this is what I came up with the command
ipchains -A OUTPUT -p tcp -s 185.68.1.2/24 www -j ACCEPT
ipchains -A INPUT -p tcp -d 185.68.1.2/24 www - j ACCEPT
1. am I using the correct source and destination values or should I use
the IP for the server nic. 185.68.1.1
2. if I am setting input filtering up on the Internet side of the card
should I use the Nic card address or the gateway address. ie
ipchains - A INPUT -p tcp -s 198.14.14.12 ftp -j REJECT -l
(Block ftp connection from the internet to the server and then logs them)
3. should I have a proxy server setup first?
4. Has anyone setup a system like above so that I can run everquest from
a network machine.
Help Always Appreciated
