I have a Firewall with a masqueraded DMZ. The adress of the external interface is not static (DHCP). The adress may change sometime. One of the servers in the DMZ needs to know the external adress.
external interface
V Internet --------- Firewall ------ Intranet

How can the Server determine the adress of the external interface or how can the firewall tell the adress of the external interface to the server
There are some services such as www.dyndns.org that provide utilities that will report your ip back to you. Especially usefull when the external interface is not a box you can hack into, not your box, or non-accessable silicon software.
