Hello !
I am attempting to set up a dial-up connection to the internet using
dynamic IP.
the connection works great and it was done "by the book", following
instrucions at the ppp man pages and docs at FBSD site.
The point I have to discuss is how to use IPFW with a dynamic IP environment.
My doubt, basically is how to set up these lines:
# set these to your outside interface network and netmask and ip
oif="tun0" # I am using tun0 to connect
onet="200.246.0.0" # My ISP's address is 200.246.0.252
omask="255.255.255.0" # I guess this is right
oip="192.168.4.17" # I have no idea what I should put here
# set these to your inside interface network and netmask and ip
iif="ed1" # my network card
inet="192.168.0.0" # the internal network
imask="255.255.255.0" # the mask seems to be ok also
iip="192.168.0.30" # the internal IP
Next I am using basically al the rules from "simple", at the rc.firewall
file, plus a couple more to ensure that netbios is not being manipulated
from outside, and also telnet will work within the LAN only.
Could someon take a look at those lines and give me some advice ?
Is there anything wrong there ? Any other enhancements ?
Thank you.
