Cannot ping Endpoint anymore

[src386]

Hi everyone,
I have been using a tunnel with /48 prefix in FreeBSD.
Everything was working, but I just realized that I cannot ping my endpoint anymore.

gif0 (2001:470:c840:254::1) is my "client endpoint" and re0 (2001:470:c840:192::1) my LAN interface.

^C
--- google.fr ping6 statistics ---
12 packets transmitted, 0 packets received, 100.0% packet loss

I already checked my public and private IP, they did not changed.

I'm stuck, I don't understand the problem... can you help me ?

What version are you using? I've been running my tunnel on FreeBSD for years and never used any of the commands that you have.

Hi, I'm using FreeBSD 10.
It was working until the last system update.
I tried to rollback but it still does not working.
Thanks.

Here's what mine looks like

ipv6_activate_all_interfaces="YES"
gif_interfaces="gif1"
gifconfig_gif1="<my public IPv4> <tunnel IPv4>"
ipv6_gateway_enable="YES"
ipv6_ifconfig_gif1="<IPv6 address given by HE followed by /64>"
ipv6_defaultrouter="-interface gif1"
ipv6_network_interfaces="em0 gif1 lo0"
ipv6_prefix_em0="</64 if you want to do RA>"
ifconfig_em0_ipv6="<IPv6 address of your physical interface>"
ipv6_activate_all_interfaces="YES"
ip6addrctl_enable="YES"
ip6addrctl_policy="ipv6_prefer"


Some of that might be old code that's no longer needed from previous versions, but it works.
