In addition to the posts about FreeSWAN, take at look at these, which are all available in Debian (woody or sid): vtun, tunnelv, cipe, vpnd, tinc, and maybe secvpn IPsec (i.e. FreeSWAN) is probably the best choice overall since it promises to interoperate with most anything that runs IPsec, but these other packages can help you get a secure tunnel up in a hurry.
