IPv6 + FreeBSD gateway
After much crashing around pulling out my IPv4 /30 from various config files, everything is working fine.
fxp0 is my LAN interface
rl0 is the interface plugged in to the modem
tun0 is the dialup tunnel device
Here are the relevant bits that get IPv6 running on FreeBSD and handing out addresses to (so far) Windows 7 clients.
---/etc/rc.conf---
---/etc/rtadvd.conf---
--- /etc/ppp/ppp.conf ---
--- /usr/local/etc/dhcp6c.conf ----
--- /usr/local/etc/dhcp6s.conf --- (used to distribute DNS servers, the below address is my HE tunnel)
The end result:
