Routing problem with Ubuntu Server and Router Cisco

[linuxgate]

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?

[linuxgate]

http://ipv6.he.net/certification/

I did and I was granted certification but irc still does not work

[cholzhauer]

You're only a newbie...you need to become sage

How do I get sage?

You take and pass more tests :)

[linuxgate]

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

[broquea]

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

Thanks
