Acces jail via ipv6

[thedeadzone]

I got the following Problem:
first my general problem is that is only have an public ipv6 address and no public ipv4 address because of my ISP, this cant be changed, but complicates my following problem.

I managed to create a ipv6 port forward for the freenas ssh service on port 55. That worked great, at least http://www.subnetonline.com/pages/ipv6-network-tools/online-ipv6-port-scanner.php says so.
I now want to get access to plex which is listening on port 3200.
But my router tells me that my plexjail and freenas both have the same interface id (don't know if its supposed to be like this) and therefore i created another one for that interface with port 3200.
When I try this port I only get access denied.

Since the port forwarding worked for the ssh port, I am thinking there is something wrong with the jail config.

edit: seems like a bug with ipv6 inside jails https://bugs.freenas.org/issues/3795

says you can work around with :

Code:

ifconfig_epair0b_ipv6="inet6 2001:db8:1::1 prefixlen 64"
ipv6_defaultrouter="fe80::1:1%epair0b"
ip6addrctl_policy="ipv6_prefer" 

but i dont what I have to change to make it work

I believe there are problems with ipv6 in the jails.. Survive would be the one to talk about it though. I think he was the admin here complaining about ipv6 and jails.

1. ifconfig_epair0b_ipv6="inet6 2001:db8:1::1 prefixlen 64"

3. ip6addrctl_policy="ipv6_prefer"
