Note: Some ports require an internet connection to be installed. Use PPP to dial with a modem and connect to the internet. Dont forget to have your firewall setup correctly, otherwise it may be blocking packets, rendering PPP useless.

backup and restore the following files:

/etc/ppp/ppp.conf

/etc/ppp/ppp.linkup

/etc/ppp/ppp.linkdown

add lines to /etc/rc.conf (if you want ppp on startup, see the man for rc.conf for specifics)

ppp_enable="YES"

ppp_mode="auto"

ppp_profile="<profile>"

ppp_nat="YES"
