877W blocks arps between wireless clients

Unanswered Question
Dec 26th, 2007

Hi,

I'm running an 877W at home with my main VLAN as a BVI between the wireless and switch ports. Historically wireless clients on the native VLAN could connect between themselves (ie ping, windows shares) but in the course of playing around with configs to fix other issues this has now broken. Port protection is not configured and I can't figure out what's wrong. I can see the ARP packets leaving one client but get no response. I'm guessing that broadcasts are being blocked, but is this a wireless level thing or part of the bridge-group? Anyone have any ideas?

I have this problem too.

There are multiple SSIDs configured, but the devices that can't communicate are on the same VLAN. I couldn't find any setting for PSPF, but the 800 series wireless guide refers to setting up access-lists which are definitely disabled.

As an example of the problem, I can't RDP to my main PC from my laptop at home (they're both working fine to the wireless router and out to the Internet) but I can if I VPN into the router. I'm thinking that wireless to wireless traffic should not go near the router interfaces but should stay on the AP card.
