Thankyou Nicholas, the suggestion you made for the change to the command to extract the external IP address works well and the script I put together now does as it is designed to do. Obviously the version of the scripts I have is different to the one you run. The 'sve ipfilters reload' does not work on my setup because there is no ipfilters script in the /etc/init.d directory but if there is at some time in the future it would certainly, as you say, reduce the amount of duplicated script on my set-up. If the scripts in '/etc/ppp/ip-up.d' are not run each time ip-up is run, then I will call this one from the ip-up script to force my set-up to function as I want it to until I find a better solution.

I am not well versed in Linux/Unix/LRP scripting and my entire Linux I'm not well versed in scripting either so there might be some problems with it but this is what I use (take straight from /etc/network.conf) EXTERN_IP=`ip addr list label $EXTERN_IF | \ grep inet | \ sed '1!d' | \ sed 's/^[^0-9]*\([.0-9]*\).*$/\1/'` I believe this either comes from a previous version of Charles' scripts or from one of the LEAF/lrp images I used in the past... > #! /bin/sh > # > # This script is run with a dial up modem connection using DHCP with a non fixed > # address to enable port forwarding to internal services after the interface > # is up so that the true address of the external interface is used in the > # port forwarding commands. ... I haven't checked that solution in detail but I believe you could avoid some "code duplication" by trying to invoke 'svi ipfilter reload' (I think that would be the right command, correct my if I'm wrong) from your scripts.
