ipchains & dhcp for internal network
 

I am trying to configure dhcp for my internal network and am having trouble with my firewall blocking it. I am using ipchains (configured through "newbie" settings on webmin at "low" setting) and have the following text show up when logging:

DHCPDISCOVER from 00:a0:cc:73:bb:d2 via eth1
DHCPOFFER on 192.168.0.3 to 00:a0:cc:73:bb:d2 via eth1
send_packet: Operation not permitted

My internal (LAN) interface is eth1 with an IP of 192.168.0.254. I've set up the dhcp script to lease from a range of 192.168.0.1 to 192.168.0.10.

Here's the section labeled for DHCP rules in my firewall script:

ipchains -A input -i eth1 -s 0.0.0.0 68 -d 255.255.255.255 67 -p udp -j ACCEPT
ipchains -A output -i eht1 -s 192.168.0.254 67 -d 192.168.0.0/255.255.255.0 68 -p udp -j ACCEPT

When I turn off the firewall, the dhcp stuff works like a charm, but as soon as I turn the firewall back on, the clients can't grab an IP from the dhcp server.

Any thoughts on what to do to fix the ipchains?

fixed it!
 

edit second line to be:

ipchains -A output -i eth1 -s 192.168.0.254 67 -d 255.255.255.255 68 -p udp -j ACCEPT
