Why don't you add that to /etc/sysctl.conf?

You don't need to run rtadvd. The following configuration should work (although I use RELENG_9, rc.conf variable naming is slightly different, but not by much):

ipv6_enable="YES"
ipv6_default_interface="re0"
ipv6_static_routes="hetzner"
ipv6_route_hetzner="2a01:4f8:61:50c0:: -prefixlen 59 -iface re0"
ipv6_ifconfig_re0="2a01:4f8:61:50c2::13"

ipv6_defaultrouter="2a01:4f8:61:50c0::1" 

Maybe you have some conflicting firewall rules?
