    In the wiki for OpenVPN (http://dd-wrt.com/wiki/index.php/OpenVPN) the warning below is displayed:

    WRT54G V1 (possibly others) will not boot (red light) using the scripts in the sections below. Documented case.

    Your rc_startup is way longer then max size for one nvram variable, which is 1024 bytes. Consider writing keys and other information to the filesystem outside of NVRAM; e.g. if you have jffs enabled store your scripts and certs there and launch the scripts from NVRAM.

    Server Configuration
    * Warning: This Script EXCEEDS NVRAM - will semi-brick you router - JTAG required to recover

    I don't get it. If that script will brick the router, why display it so that others can brick their router??
    So is it a real option that my router will become a brick when I use this script?
    I can't use jffs or any other external file system when the VPN flavour of the dd-wrt24 firmware is used so how can I use pki when only nvram is available.

    My routers are a wrt54g V2 and a wrt54gl V1.1 and use dd-wrt24 vpn firmware.
    Currently they use static keys for a connection between them but I want to use pki instead.

    Unless you can get someone with more knowledge on why it bricks the WRT54G v1 assume it is a warning to those who want to listen to advice from others.
