Multicast Ethernet frames not bridging between wired and wireless, Netgear CPE
I've a Netgear 7550 B90 provided by Frontier. (Yes, it's my only choice other than VSAT. Rural US. Yes, I am already looking into getting my own CPE, but humor me.) Since Frontier doesn't support IPv6, I've linux box on the LAN building an AYIYA tunnel, and doing the usual router thing on the wired Ethernet. Everything on the wired side works splendid. Wireless clients didn't seem to want to play. Further digging indicates that RA and NS don't cross the bridge from wired to wireless. Manually assigning IPv6 address and nailing NDP entries allows ICMPv6 echo request to work. Has anyone seen this class of device drop multicast between the wireless radio and the wired ethernet switch? Or am I brain dead this morning and missing something obvious? Heck, I even tried disabling WPA2 thinking it was some wonky encryption thing. Thanks, -cjp

Are you using the Netgear device for wireless, or is there a wireless adapter/card/whatever in your linux box? If you have linux running on the wireless thingy, u might find the proxy_ndp options useful (/proc/sys/net/ipv6/...) I have a Netgear WG102 running as bridge and it worked without any further tweaking. But, I transport the data via tagged VLANs up to the Netgear who extracts them for each SSID individually. -- Dan Lüdtke www.danrl.de

Netgear was the wireless/wired/ADSL from the provider. Workaround was to make that an ADSL-Ethernet bridge and run PPPoE on another, unbroken, wireless router (WRT54G OpenWrt). Thanks, -cjp
I've seen some Linux boxes in bridge mode do strange things with wireless and ipv6. Using wds mode resolved it. Is the wireless in wds mode? On Feb 9, 2013, at 2:31 PM, "Christopher J. Pilkington" <cjp@0x1.net> wrote:
