secure remote access

I need some direction from one of you networking experts out there. I'd

like to securely access a "work" server (RH9) from home. Both machines 
are connected to the internet via a NATting dsl modem/router, each 
having a dynamic ip address (that rarely changes). What should I use? 
(simply) SSH? OpenVPN? OpenSWAN? Any pointers to HOWTOs?
