FreeBSD Port: radvd-0.7.2

[DLdaten at aol.com]

Hi,
I do hope you can help me to solve the following questions:
- in which way I can use radvd to convert restricted Lan-connections using 
both stacks V4/V6.n How the Kernel is to be patched. Give me links or detailled 
instructions please.
- how radvd can be combined with nat-pt ? 
- In which way squid/apache can be used for both stacks?
- Do you know a scenario using an secured LAN (using V6) and an unsecured LAN 
using 
  standard office-communications, which ca reproduced by me?
- Is it possible to connect RADIUS-authenication released clients with the 
secured LAN-using V6.
My e-mail address is hhmw at gmx.net
Best regards and Merry Christmas - days.
Herbert
