I don't think so (sorry for forgetting to mention that). 

Upstream router:

ns.bravo.dnslab:/root#sysctl net.inet6.ip6.accept_rtadv
net.inet6.ip6.accept_rtadv = 0
ns.bravo.dnslab:/root#sysctl net.inet6.ip6.forwarding
net.inet6.ip6.forwarding = 1

Client:

client.alpha.dnslab:/root#sysctl net.inet6.ip6.accept_rtadv
net.inet6.ip6.accept_rtadv = 1
client.alpha.dnslab:/root#sysctl net.inet6.ip6.forwarding
net.inet6.ip6.forwarding = 0

I'm still at a loss.

Regards,

Johan
