Hi,<br><br>I am trying to do some dynamic configuration from dhcpd.conf, but I am running into a problem with my 'on release' section. It seems 'config-option routers' is not known within it's scope or something? (see logfile below) I need to know this IP because I passed it to iptables in my 'on commit' section. In order to delete this iptables rule I need to replicate it exactly with the -D, otherwise it wont be deleted. Any help on this would be appreciated.<br><br>I am a bit confused on what exactly I can pass to the binary-to-ascii function, and what I can dissect from it. I can find some configurations from people on the internet, but not a clear overview on that subject. Any pointers on this are also very welcome.<br><br>====config====<br>ddns-update-style ad-hoc;<br><br>shared-network home<br>{<br> subnet 192.168.10.0 netmask 255.255.255.0<br> {<br> range 192.168.10.3 192.168.10.20;<br> option routers 192.168.10.1;<br> option subnet-mask 255.255.255.0;<br> }<br><br> on commit<br> {<br> execute<br> (<br> "/home/x/iptables.sh",<br> "add",<br> binary-to-ascii(10,8,".",leased-address),<br> binary-to-ascii(10,8,".",config-option routers)<br> );<br> }<br><br> on release<br> {<br> execute<br> (<br> "/home/x/iptables.sh",<br> "remove",<br> binary-to-ascii(10,8,".",leased-address),<br> binary-to-ascii(10,8,".",config-option routers)<br> );<br> }<br>}<br>===/config====<br>
