[CentOS] Centos 4.3: VPN recommend/ howto anyone?

I'm also a fan of CentOS, but take a look at M0n0wall @ http://m0n0.ch .
That's what I use for my VPN. At HQ, I use M0n0 on a CF card, with a decent
Monarch 1U system, no hard drives. For the remote offices, I use Soekris
NET4801 boxes. All embedded, no moving parts, very sweet to use.
