FreeBSD firewall and dynamic IP-address

Mikessu · 04-14-2004, 03:18 PM

I have just installed FreeBSD 4.9 and got it somehow working as router. Now I'd like to get firewall working and I've read this manual: http://www.acme.com/firewall.html but I'm stuck with the firewall configs. It says I should define IP-address but I dont know what to put there because my IP address changes every time I connect internet.

Code:

        
# set these to your outside interface network and netmask and ip
        oif="ep0"
        onet="192.0.2.0"
        omask="255.255.255.0"
        oip="192.0.2.1"

it says for 5.1, but it should work with 4.9 as well.

I installed this and now it works well but I haven't get dcgui-qt work in active mode (It is a p2p program that requires port 9176 tcp to download files and 9176 udp to search files).

I have added following lines to ipf.rules

Quote:

pass in quick on tun0 proto tcp from any to any port = 9176 flags S keep frags keep state
pass in quick on tun0 proto udp from any to any port = 9176 flags S keep frags keep state

and following lines to ipnat.rules

Quote:

rdr tun0 0.0.0.0/0 port 9176 -> 192.168.0.4 port 9176 tcp
rdr tun0 0.0.0.0/0 port 9176 -> 192.168.0.4 port 9176 udp

Downloading files works well but I can't use search.
