CARP and ( GIF tunnel
« on: October 30, 2017, 04:18:07 am »
I setup CARP with one ISP and 2 PFSense boxes. Everything works as expected if I disable CARP on the primary.

The only thing is the tunnel, everything will go in Master status on the slave if i set 'Disable CARP' on the primary. But IPv4 works, but IP6 not. The Gateway to is shown as Online on the slave, but there is no IPv6 connectivity. I can ping the IPv6 CARP ip, also the IPv6 slave IP but if i ping the GIF tunnel local address or GIF tunnel remote address (or any other IPv6 outside LAN) then i get a PING: transmit failed. General failure.

My setup:

GIF tunnel is setup with this manual: Because of CARP i change the GIF parent interface to the WAN CARP IP.

Also created a IPv6 CARP IP on top of the LAN-interface (and set my clients to use this IP as gateway).

I have IPv6 internet, can ping6 the master, slave and CARP IPv6 IP-adres. So i think everything is setup correct?

Compare the interface settings (ifconfig -a) and routing tables (netstat -rn) on both nodes in each state, see if there is anything different.
