pfsense wireless AP - lost packets

[AndreyS]

Hi,

I'm trying to setup wireless AP using pfSense (which is based on FreeBSD 6.2). I have Win2000 laptop, which connects to my existing Linksys AP without any problems. But when I try to connect to FreeBSD it cannot get IP address.

When I run tcpdump on FreeBSD side and wireshark on W2K I see that association is established, then W2K sends DHCP Discover packet, which reaches FreeBSD. FreeBSD answers with DHCP Offer but I never see it on W2K side.

I realize this is not exactly FreeBSD question, but provided the same W2K machine can connect to another AP I suspect some misconfiguration on FreeBSD side. But I don't understand what to look for.

I asked this question on pfSense forum but didn't get any answer. Also I tried to disable firewall but it didn't help. Anyway if I understand this correctly I wouldn't see this packet in tcpdump if it was blocked by a firewall.

I use PCChips motherboard (Via C3 based) and Edimax EW-7128g wireless card in hostap mode. W2K machine has D-Link DWL-650 Wireless Cardbus Adapter, 802.11b.

What could be the problem?
