Hello,
I am trying to tunnel my server to IPv6. Without any success. I followed this tutorial:
http://lowendbox.com/blog/ipv6-with-a-hurricane-electric-tunnel/
Configured ifcfg-sit1 like this:
DEVICE=sit1
BOOTPROTO=none
ONBOOT=yes
IPV6INIT=yes
IPV6TUNNELIPV4=216.66.84.46
IPV6TUNNELIPV4LOCAL=94.100.24.139
IPV6ADDR=2001:470:1f14:e44::2/64
IPV6_DEFAULTGW=2001:470:1f14:e44::1
ifdown sit1
ifup sit1
Ping6 ipv6.google.com
[root@bella ~]# ping6 google.com
PING google.com(ea-in-x65.1e100.net) 56 data bytes
Nothing happens. Who can assist me?

Is it a VPS or dedi, if VPS what kind?
ip -6 r
ip -6 addr
Please.
It's a VPS on ESXi.
Here are the results. I can't paste them in this forum.

No package ipv6 available.
You need to configure both sit and network file to make it work. But I'm on my phone, so no config sample.
I am also using CSF. It says TCP6OUT, UDP6OUT and ICMP6OUT are blocked by default. How to allow them?
Right now:

What is the /etc/resolv.conf value?
; generated by /sbin/dhclient-script
search xseu.net
nameserver 8.8.8.8
enable csf ipv6
add ipv6 resolver
add this
Got this:
http://pastebin.com/13v2K4X8

/etc/sysconfig/network
NETWORKING_IPV6=yesYup

Okay, I know for sure it's a problem with CSF.
csf and lfd have been disabled
[root@bella ~]# ping6 ipv6.google.com

^C
When enabling, it doesn't work anymore.
I restarted CSF and everything works now! Thanks guys
