=Information=
The Comtrend AR-5382u is an ADSL2+ router with 4 Ethernet ports, wifi, and usb port (for 3g fallback). It also supports IPv6. As of Feb 2010 they are available as [http://aa.net.uk/broadband-accessories.html pre-order]. There are still a few bug fixes which we have passed back to Comtrend and are awaiting firmware updates to resolve these issues.
=Known Problems=
==There is no IPv6 option in PPPoA mode. ==
This is critical for us and other UK ISPs as PPPoA is the preferred mode. Also, some lines can only handle PPPoA.
==IPv6 in PPPoE mode is forgotten when editing==
The work around is to remove the WAN settings and re-add them. (which will loose access if done from the WAN)
==Prefix delegation via DHCPv6 only works with a /48==
At the moment, lines will have to be set with a /48 and we'll route the whole block.
This is important to avoid waste, but also to allow multi-site customers to manage their /48 giving different sites different /64
==DHCPv6 on WAN/PPP does not request IPv6 DNS servers==
These will need to be set manually in the router
==Router announcement on LAN is not providing DNS servers==
Manual configuration required on the computers.
==Router is not renew/rebinding the DHCPv6 on the WAN on PPP restart==
If changes are made, such as adding/changing IPv6 block, then a reboot is required.
==We think IPv6 should be enabled by default on WAN and LAN route announce==
The router seems to fall-back to only IPv4 operation if the ISP does not support IPv6, so this seems safe. IPv6 is the current version of internet protocol so it seems odd that it is disabled by default.
