Hmm, all the current config files are a snapshot of "gate.muc.bieringer.de" 
which is indeed a gateway.
The case is that IPv6 is independed from IPv4 NAT traffic.

I'm routing IPv6 traffic via 2 tunnels to my Internet/Intranet gateway 
(official IPv4). This gateway decapsulate the IPv6 and route this native 
internally.

Send questions...

Hmm, should work. Install radvd on the gateway, configuring prefix 
3ffe:2a00:100:7ba2::0/64 for sending on local net.

Configure on gateway:
i.e. ifcfg-eth0: IPV6ADDR="3ffe:2a00:100:7ba2::1/64" (manual address on the 
router)
i.e. ifcfg-sit1: IPV6TUNNELIPV4="IPv4 address of tunnel endpoint"
static IPv6 routes
sit1                            3ffe::/16
sit1                            2000::/3


Clients: if using radvd, no configuration is needed (only IPv6 enabled kernel).

In case of manual setup, choose another address for the clients like i.e. 
ifcfg-eth0 IPV6ADDR="3ffe:2a00:100:7ba2::2/64" and enable static IPv6 
routing to the gateway "3ffe:2a00:100:7ba2::1" for "3ffe::/16" and 
"2000::3" through eth0:
static IPv6 routes
eth0                            3ffe::/16               3ffe:2a00:100:7ba2::1
eth0                            2000::/3                3ffe:2a00:100:7ba2::1
