 WOW!!!
 What a nifty script!

 Isn't small mistype here:

  while read d ip      <---  "d"  is it correct?
     do 
Hi Tom,

Yes, it is correct.  It reads the output of the diff command which has lines like:

< 1.2.3.4
...
  5.6.7.9 
It puts the < or > into $d and the IP address into $ip.
Then it either deletes or inserts the IP address in the list using the case/esac on $d.

You can copy/paste the script and run it and check using:

iptables -L ipipfilter -vn

to see if it works OK.   You can run it again and nothing should change.  When all is OK
you can change the ampr-ripd startup to add the -x option and modify the firewall to use
ipipfilter instead of ACCEPT for -p 4.

Make sure in the startup sequence of the system you run the script once before the
firewall is loaded, so that the ipipfilter target does exist before the rule for -p 4 is
loaded.
I have my own script that sets up the entire firewall, so I call the script from there.
