[RESOLVED] how do i set up vpn

[ylen13]

finally got arround setting up my router in the office and using the guide i think i did it right. Now ready to set up software on my home pc problem is seem the software no longer available(guide was written in 2000). Any recomendation on what program to use for vpn prefferable a free one. Also do i need to set anything up on the office comp or is router vpn set up enough to let me access comps in my office?

TIA

edit:i checked my firewall log in my office and i see this
2006-03-04 15:19:00 8000/TCP from 66.159.251.x:3201 to 72.25.125.x:8000 Invalid TCP packet received, dropping packet (i replaced with x to hide ip)

obviously i didn't set up everything correctly, could use some help
