[OpenWrt-Devel] WDS and broadcast/multicast?
Hi all, [sending this to -devel, as I haven't had any response on -users, hope this is okay] I've recently set up WDS between two WRT54Gs (one v2 and one v4). However, with WDS enabled it seems that wireless clients aren't receiving broadcast or multicast packets. Some details: * Both WRTs are running 8.09.1, bcrm-2.4 * There are wired hosts connected to both WRTs * There are a few wireless clients * Wireless is WPA/PSK If I do a broadcast ping from the wired network, only other wired hosts will see the ping. However, this *includes* wired hosts on the other side of the WDS link. Wireless hosts do not see any ping packets. Same applies for UDP packets sent to the local broadcast address, as well as mutlicast packets. If I do a broadcast ping from a wireless client, the wired hosts see the packet as expected. If I disable WDS (and turn off the WDS-connected WRT, because it's now isolated from the network), then wireless clients are able to see the broadcast packets. ARP seems to work fine in both cases though. Is this a known issue? Or perhaps a mistake in my configuration, or is there something I need to do to enable to allow broadcast and multicast packets to be sent on the wireless network? I've included /etc/config/wireless for both WRTs below. Let me know if there's any other information that might assist. Any help would be much appreciated, this has got me stumped :) Cheers, Jeremy /etc/config/wireless - config wifi-device wl0 option type broadcom option channel 5 config wifi-iface option device wl0 option network lan option mode ap option ssid "" option encryption psk option key "" config wifi-iface option device wl0 option network lan option mode wds option bssid"" option ssid "" option encryption psk option key "" ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Can you give comparative squashfs sizes instead? Also, this may takes signficantly long periods of time for large numbers of packages. Have you tested with more than the base setup?

I think I did not ask it to strip down all shared libraries, thus it only stripped down the linker. I will try to look at it later in the weekend. -- Best regards, Florian Fainelli Email: flor...@openwrt.org Web: http://openwrt.org IRC: [florian] on irc.freenode.net --- signature.asc Description: This is a digitally signed message part. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Wouldn't that mean that fewer programs would result in more removal (due to more unused bits). Or do you strip all libraries and not just uClibc?
