IPv6 Router on a Stick

Hi guys and gals ....

So Im playing with IPv6 (yes I'm a totally newbi with this)

I have the following setup ....

Datecenter Switch (my uplink / internet connection) = 2001:470:1:66e::1

EdgeRouter eth0 = 2001:470:1:66e::2

EdgeRouter eth1 = downlink to my EdgeSwitch

So ..... I can poing my EdgeRouter via 2001:470:1:66e::2 from the internet / external and it works nicely.

I've setup the default router for IPv6 to go out to the uplink to the datacenter, all working perfectly.

I've added 2001:470:1:66e::10 to a server that sits connected to my EdgeSwitch ..... but I cannpot reach it.

On the EdgeRouter > Routing I dont see how / where I can add static routes or any route for the IPv6 range .....

Any ideas please / pointers.

thanks
