Hostap Ping Problem

[Emir Uner]

Hi, I have a problem with hostap.

Machine A
Server: Gentoo Linux
Kernel: 2.6.31
Wireless card: RaLink RT61
hostapd 0.6.9
IP: 192.168.40.254/24
Using: WPA2-CCMP

Machine B
Client: Gentoo Linux
Wireless Card: ipw4965
using wpa_supplicant
IP: 192.168.40.1/24


I manually configured both sides ip addresses:
When I ping from Machine A using command below:

ping 192.168.40.1

And run tcpdump on Machine A I can see
ICMP packets sent from Machine A but no replies

Meanwhile running tcpdump on Machine B I can see
both ICMP request and generated Responses by Machine B

So it seems that Machine A can send packets to Machine B
but Machine B cannot send packets to Machine A.

Am I missing something obvious?
Regards
