IPv6

[Emab]

I want to make my netork be able to reach IPv6 network over the Internet.

I can setup my server to use IPv6, but how I can setup pfSense?
I tried to use ngnet (https://tb.ngnet.it. I setup a tunnel. I have this information:

| Tunnel Info |
| Server IPv4 Address | ...**** |
| Server IPv6 Address | :::::**** |
| Server IPv6 Link Local Addr | :::**** |
| Client IPv4 Address | ...* |
| Client IPv6 Address | :::::**** |
| Client IPv6 Link Local Addr | :::**** |

And the site generate this script fot FreeBSD:

#!/bin/sh
gif_ifaces=`ifconfig -a|grep -w gif[0-9]*|grep -v UP| grep -v inet6 | awk -F":" '{print $1}'`
gif_iface=`echo $gif_ifaces|awk '{print \$1'}`
if [ -z $gif_iface ]; then
echo "No gif interfaces available."
echo "Tunnel can't be configured"
exit
fi
ifconfig $gif_iface create
ifconfig $gif_iface tunnel ClientIPv4Address ServerIPv4Address >> /tmp/tb.log
ifconfig $gif_iface inet6 ClientIPv6Address  ServerIPv6Address prefixlen 128 metric 1 >> /tmp/tb.log
route add -inet6 :: -prefixlen 0 -interface $gif_iface
echo "ClientIPv6Address $gif_iface" >> /tmp/tb.gif

Thanks for help!

We have a tunnel endpoint option I think, never used it.

If you want to use the script, stick it in /usr/local/etc/rc.d and make sure to chmod a+x it.

I saw the endpoint option, but if i put only the ipv4 address threre, IPv6 is not running… There is something wrong?

I think that the best solution is to use the script, but i have a dinamic IPv4 so how i can modify the script to run every time the IPv4 change? and get automatically the IPv4 address?

Thanks!

I really don't know.  I honestly have never used ipv6.

This gets a LOT more involved but you could try launching your script from /etc/rc.newwanip

Ok, I can try this, but how can I edit the script to get automatically my IPv4 address?

[sullrich]

Look at /etc/rc.newwanip

Look at /etc/rc.newwanip

Ok, if I undestrand correctly I have to put the script here… it's correct?

[sullrich]

No, you need to read /etc/rc.newwanip and hook you're script in appropriately.

Ok… I'll check tomorrow.... now it's to late for me...

Thank you!

If I run this script:

#!/bin/sh
gif_ifaces=`ifconfig -a|grep -w gif[0-9]*|grep -v UP| grep -v inet6 | awk -F":" '{print $1}'`
gif_iface=`echo $gif_ifaces|awk '{print \$1'}`
if [ -z $gif_iface ]; then
echo "No gif interfaces available."
echo "Tunnel can't be configured"
exit
fi
ifconfig $gif_iface create
ifconfig $gif_iface tunnel ClientIPv4Address ServerIPv4Address >> /tmp/tb.log
ifconfig $gif_iface inet6 ClientIPv6Address  ServerIPv6Address prefixlen 128 metric 1 >> /tmp/tb.log
route add -inet6 :: -prefixlen 0 -interface $gif_iface
echo "ClientIPv6Address $gif_iface" >> /tmp/tb.gif

it do any permanent change?
or it's enought to reboot the system to lost these changes?

[Emab]

I'm trying to run the above script…
but I need some help...

The script want a GIF interface... what I can do?

[Emab]

Ok…how I'm able to run the script and I have IPv6 connectivity on the pfSense PC.

What is the best rule, for security reasons, to allow IPv6 traffic?
