BT4 RC1 VMware Fusion w/ Alfa r8187 Drivers - Malformed Packets on at0

[mascasa]

Subject line basically says it all. Clients can associate with my softAP and I see DHCP Discovers on wlan1 but all I see in Wireshark are malformed packets and unknown frames. No DHCP DISCOVER requests logged in the DHCP server running on at0. Anyone else have this issue or have any suggestions?

Same issue here, but problem is only present when external interface and soft AP are both present on open networks.

Commands used:

iwconfig wlan0 channel 8 mode managed ap auto essid SuperSecretNetwork
dhclient3 wlan0

Once wlan0 is associated and has external acces...

airmon-ng start wlan1

Comes up without issue, so...

airbase-ng -P -C 30 -e "Free Public WiFi"

Everything good so far, so...

ifconfig at0 IP.ADD.SS.1 netmask 255.255.255.0
ifconfig at0 up
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o wlan1 -s IP.ADD.SS.0/24 -j MASQUERADE
service dhcp3-server start

At this point everything should be good... but it isn't. Packets coming into at0 are 36 bytes short, and misidentifying as FC packets instead of Ethernet. If the entire process is done using wlan0 on an encrypted connection, however, the whole setup works perfectly.

Anyone have a thought?
