Hello,
I have configured my tunnel with this configuration
auto he-ipv6
iface he-ipv6 inet6 v4tunnel
address 2001:470:1f12:184::2
netmask 64
endpoint 216.66.84.42
local 192.168.1.27
ttl 255
gateway 2001:470:1f12:184::1
and I open up ping requests from HE but when I ping any IPv6 address, I don't receive any packets
I need your help.
Add the following firewall rules at suitable priority
ip6tables -A OUTPUT -o he-ipv6 -j ACCEPT
ip6tables -A INPUT -i he-ipv6 -m state --state ESTABLISHED,RELATED -j ACCEPT
ip6tables -A INPUT -i he-ipv6 -j DROP
iptables -A INPUT -s 216.66.84.42 -p 41 -j ACCEPT
iptables -A OUTPUT -d 216.66.84.42 -p 41 -j ACCEPT
If it is still not working, try changing the NAT firewall.
