Hello all!
I have what I'd probably call a slightly advanced networking setup, and I can't seem to get native IPv6 to behave, no matter what I try.
I am using my RG (NVG589) in normal mode (not passthrough) because I am letting it do all the IPTV traffic, and any DHCP for that subnet (VLAN) on my home network.
I have a Linux machine acting as my LAN gateway that provides DHCP and DNS (and firewall, etc etc) to all my hosts, on a VLAN separate from the IPTV VLAN.
This machine is allocated a STATIC IP from the RG.
I've already had to wrestle with the RG aggressively timing out my long-running connections (ssh, etc), by enabling keepalives at a fast (<60 sec) interval. I'm mostly over this issue, but it makes me sad that I have to do this. I should be able to tell the RG not to time out long-running TCP connections unless they are idle for more than some much-longer threshold of time (pref. configurable). But that is another issue ;)
ANYWAY: IPv6:
I'd prefer not to run a tunnelbroker (he.net) tunnel, especially since it's clear AT&T has v6 at my RG, and since it's silly to have to maintain that and deal with any issues between me and the he.net endpoint degrading my v6 performance... etc.
More info:
As per the Broadband Status page, there is a /60 allocated to my router:
(address munged, preserving the last nibble)
Global Unicast IPv6 Address 2602:306:cafe:bab0::/60
On the "Home Network" page, it shows some of the allocation:
Global IPv6 Address 2602:306:cafe:bab0::1/64
Router Advertisement Prefix 2602:306:cafe:bab8::/61
IPV6 Delegated LAN Prefix 2602:306:cafe:bab8::
Now, if I give my Linux box an IP in 2602:306:cafe:bab0::/64, I can ping the RG, and I can ping the world: YAY.
However, I need to be able to route another /64 THROUGH that Linux machine, which runs radvd to allocate IPv6 to machines on my LAN.
How do I tell the RG to route the next /64 (2602:306:cafe:bab1::/64, or anything, really) to my Linux machine, so that it can allocate addresses to machines behind it?
This is trivial routing, but something tells me I'm trying to be "too fancy" for AT&T :-(
Any thoughts/pointers/help/etc?
Thanks,
-Taner
