Currently I have an ISP that provides an IP address via DHCP, and the address occasionally changes. What I want to do is to retrieve the IP address of the Internet side interface (eth0) of my firewall without manual intervention, and stuff that value into a variable. I need the value for additional DNAT rules because I have a web server and email server on my LAN.
This sounds like it should have a really simple solution (like some Bash command or something), and I've looked all over to find how to do this, but haven't seen it anywhere, so forgive me for my ignorance if I've overlooked something outrageously simple.
Most DHCP clients provide some sort of exit hooks, where the user can, at his discretion, do whatever he wants with the newly provided values. For dhclient this is /etc/dhclient-exit-hooks, dhcpcd uses dhcpcd.exe by default in /etc/dhcpd, for pump I have no info.
