Turn the problem on its side.... #!/bin/bash cat /etc/iptables.header /etc/iptables.newstuff /etc/iptables.trailer > /etc/sysconfig/iptables iptables-restore < /etc/sysconfig/iptables (basically the solution I did for an NFS server, where 'newstuff' and /etc/exports were both machine-generated by a perl script that read a config file of authorized clients.
