Hi.
I'm running a "simple" firewall with the rc.firewall script, and have
added a few lines of my own to it.
I have a dailup connection to my ISP, so I can't use a "real"
IP for my ISDN card.
Anyone know how to implement the IP I'm getting from my ISP
into my ipfw rules?
ex.
# set these to your outside interface network and netmask and ip
oif="isp0"
onet="0.0.0.0"
omask="255.255.255.0"
oip="0.0.0.1"
# set these to your inside interface network and netmask and ip
iif="xl0"
inet="10.0.0.0"
imask="255.255.255.0"
iip="10.0.0.10"
# Stop spoofing
${fwcmd} add deny all from ${onet}:${omask} to any in via ${iif}
This rule will be all wrong as it is today.
Hope you understand what I'm after here :)
Regards
Eirik
