-----BEGIN PGP SIGNED MESSAGE----- Why don't you try the ip-up script as you talk about ppp. I know that SuSE has an ip-up script with firewall rules set up (with ipfwadm as I remember). - --- Bogdan Zapca System Administrator SC EcoSoft SA Internet Service Provider 1-7 Deva st, Cluj-Napoca, Romania Tel: +40 64 199696 PGP: http://www.itotal.ro/lupe@admin2.ecosoft.ro.pgp http://www.ecosoft.ro On Thu, 27 Jul 2000, Charles Price wrote:
At the moment I just have a masquerading firewall but I'm hoping to add a shell script containing ipchains rules onto it soon. At the moment the script defines variables at the beginning and uses them later. ie.
#!/bin/sh
EXTERNAL_INTERFACE="eth0" IP_ADDR="192.168.1.20"
ipchains -A input $EXTERNAL_INTERFACE -s $IP_ADDR etc.etc.
Although there is a problem.
I've got a dynamically assigned IP address, so in theory I'd have to re-configure the script every time PPP was started. Is there and environment variable in BASH to do the job $IP_ADDR or something like that, but then how does it know which? eth0 or ppp0? I feel I'm going to have to write a more cunning piece of script for this one. Any ideas?
Kind Regards
