help understanding dhcp - Page 2

You have to redirect both directions from and to.
As I understood, you have eth1 and wlan2, where is DHCP server located (in other words what IP it is listening)?

should listen on 67 and send to 68.comps send to 67 and listen 68. why would anyone change that value or can they even. I reloaded. Linux was droping the connection and I had dfrag this comp and get some rest. When I go to the repo's and install stuff Is there anything I can load or do diferantly that might help me.maybe a tool for working with iptables like fc has. I think this time around I want to start with route2 and maybe a port scanner. Or something I can monitor the ports with.

Hello dvdljns,

nimnull22 asked you for the IP-adress of the nic of your DHCP-server. That's something different than the port-numbers. I'd strongly recommend you to read a tutorial about the basics of networking.

I did check my earlier posts I think there is a link to it. Could have swore someone said it would not have one. how do I descover or assign it.

Anybody know where the startup scripts are in this thing. Since everything has to be done in xterm, I might as well with text. loading the xserver is a wast of time and linux is so slow.

Well, your DHCP-server has an IP-adress, for example 192.168.1.5, then (normally) the server would listen to the 192.168.1.0/24 subnet. It is suggested that you assigne an IP-adress (a static one) to the server. If your not sure if it has an IP-adress you may look at the output of "ifconfig".

If you have to assign an IP-adress to the nic of your server you'll have to edit the script for your networkconfiguration. Since I'm not familiar with your distro, I'd recommend to look into its manuals.

Since after all your posts I still haven't understood the setup of your network and you fail to post a draft of your network it is very difficult to help you. Otherwise it is very exciting to guess what you're really doing ;-).

But actually for IPTABLES it called "forward"
Something like this (just an example):

-A FORWARD -i eth0 -o wlan1 --sport XX --dport XX -j ACCEPT
-A FORWARD -i wlan1 -o eth0 --sport XX --dport XX -j ACCEPT

"echo 1 > /proc/sys/net/ipv4/ip_forward"
