Re: [SOLUTION!] How do I find my local IP assigned by my ISP when using pon, etc?
First,
Thank you to everyone that sent email about my question.
The solution turned out to be very simple.
When pon causes a connection to be made to an ISP, the script
/etc/ppp/ip-up
is run. In Debian (2.2r3) this script accepts several parameters from
pppd. They are set and exported as:
PPP_IFACE
PPP_TTY
PPP_SPEED
PPP_LOCAL
PPP_REMOTE
PPP_IPPARM
ip-up then runs all scripts it finds in
/etc/ppp/ip-up.d
In that directory I created a link
ln -s /etc/ipchains/rules-T22 firewall-up
and in my firewall rules set I set
IPADR_INTERNET="$PPP_LOCAL"
and I am done.
(I have a regular set of ipchain rule files, so this is the only link I
need to my previous work).
I made the corresponding links, etc for ip-down.d
Very slick!
Thanks again.
Regards,
Randy
