[f-nsp] Question about IPv6 SSH Access Group on Jetcore

Any up for this post ?


---------
I seem to be unable to get SSH Access via IPv6 restricted on a Jetcore 
with Provider Firmware 08.0.01v. 

After reading the manual, my understanding is that the following should 
restrict ssh access only to subnet 2001:db8:1:2::/64: 

ipv6 access-list ipv6-mgmt-in 
permit ipv6 2001:db8:1:2::/64 any 
ssh access-group ipv6 ipv6-mgmt-in 

As all IPv6 acl's have an implicit deny ipv6 any any rule as soon as any 
permit rules are configured this should block everything but the subnet 
2001:db8:1:2::/64 from having access using SSH. 
But when I test from any other IPv6 address I can log on to SSH without 
any trouble. 

I tried to use a manual deny ipv6 any any rule in the acl without any 
difference. 


Does anybody successfully restrict SSH Access on IPv6 and can give me a 
hint here?
