Hello, I configured my ipv6 tunnel. My files of configuration  are following:

[/quote]
/etc/network/interfaces

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
auto he-ipv6
auto sit0

# Interfaccia di rete interna
iface eth0 inet static
address 192.168.15.100              <--- Lan Ip Server
netmask 255.255.255.0
broadcast 192.168.15.255
gateway 192.168.15.1                <--- Lan Ip Router


iface he-ipv6 inet6 v4tunnel   
endpoint 216.66.80.98
ttl 64

iface sit0 inet6 static
address 2001:470:25:537::2     
netmask 64
up ip -6 route add default dev he-ipv6
down ip -6 route del default he-ipv6

In sysctl.conf I have set

net.ipv6.conf.all.forwarding=1
[/quote]




now you say what's the problem? The problem is that it does not connect to ircnet :

In Cisco router I disabled DMZ setting but NAT is enabled and only two ports point to the local ip of the router and are open to the outside. HELP ME PLEASE !

Irc is  blocked by  default unless you have earned the sage certification

How do I get that certification?

I completed the test and got the certification SAGE, but the connection to irc still does not work, why?

Log into the broker, go to your tunnel's details page, there should be a button to unblock IRC access.
