Using the Erase button as outlined above means any configuration made to the
4300T will be lost. Additionally the VoIP ALG registration code must be re-entered
in the 4300T as covered in Chapter 4: System Diagnostics, viewing the ALG
registration code. Erasing the configuration means that IP phones installed behind
the 4300T will not work and Internet connectivity or network access for PCs will be
down until the system is reconfigured.
