Hi Sean, I use the following command in my rc.firewall: ifconfig ex0 | grep "inet " | awk '{print $2}' Where ex0 is my ethernet interface. The awk part just takes the 'inet' line and prints out the second term. Zev >Hello, > > I edited a general-purpose firewall rule script and use it on >a dual homed machine. It provides nat and filtering. My question >is, right now I have the value for the external interface ip number >'hard-wired' into the script.
