As another option to consider: I also have an RT-N66U, but I reflashed it with Shibby Tomato (tomato-K26USB-1.28.RT-N5x-MIPSR2-116-AIO-64K.trx). The functionality offered is very impressive, as long as you're not overwhelmed by options.
Since I didn't get into the trial for native IPv6, here's what I've done. Warning: this is not for the faint-hearted!
family SSID tech SSIDs (2.4+5GHz)
^ ^
^ WAN ^ LAN
Plusnet <------- TG582n ------------------ Tomato ---------------
HE <- - - - - -' family network techie network
(v4 only) (v4+v6)
* I configured a 6in4 interface on the Plusnet TG582n router with a tunnelbroker.net (Hurricane Electric) account, as per the instructions at
http://community.plus.net/forum/index.php/topic,106578.0.html/* However I
didn't configure the TG582n LAN side interface with v6. I wanted to keep the "family" part of the network free of IPv6. HE's tunnelbroker service is, after all, a free service with no service level agreement, and I don't want to get into any additional troubleshooting.
* Under Advanced > Routing, I configured the Asus Tomato in "router" rather than "gateway" mode (which means it routes between WAN/LAN but no NAT), gave it a different v4 subnet on its LAN side, and added a static route for this subnet on the TG582n. Tomato serves DHCP for its own LAN network. (Incidentally, the web interface makes it much easier to assign addresses statically than the TG582n)
* I configured my tunnelbroker /64 on the LAN side of the Asus Tomato, pointed IPv6 defaultroute at the TG582n, and configured a static route on the TG582n routing this /64 to the Asus. Since the family network has no v6 addresses, I used the link-local addresses (FE80::xxxxx) as the next-hop addresses in both directions.
Tomato doesn't let you add IPv6 static routes directly, so I had to frig it by using a script triggered on WAN up (under Administration > Scripts)
ip -6 route add ::/0 via fe80::xxxx:xxff:fexx:xxxx dev vlan2
And for the TG582n you have to do it through the command line (:ip rtadd)
:ip rtadd dst=2001:470:aaaa:aaaa::/64 gateway=fe80::yyyy:yyff:feyy:yyyy intf=LocalNetwork
Amazingly, It all actually works
🙂A much simpler option would be to get rid of the TG582n and use the Asus as the border router - I have fibre so it's a PPPoE connection to the BT modem. However I like the Plusnet router being there so I can continue to play with the Asus without breaking the main network, and it was fun to debug
🙂
