I've a somewhat strange issue, which I can't explain to myself and didn't find anything similar here in the forums.
I've the following setup (at home):
ASG 120
eth1+eth2 bridged
SMC Barricade 2804 WBR (wireless router) connected to eth2
internal network connected to eth1
Same issue if the wireless router is connected to the bridge or directly to eth1
ASG IP intern: 192.168.123.252
DHCP enabled on ASG: Range 192.168.123.101 - 200
wireless router: fixed IP 192.168.123.254
All cable clients: working fine
Windows 7 / Vista wireless clients: working fine
Windows XP wireless clients: taking like 30 seconds for receiving an IP adress, but finally getting one
Android, Windows Phone 7 (I think iOS as well, not too sure) clients: IP adress cannot be received from DHCP. Manually configured Android clients are working fine, WP7 cannot be configured manually.
The DHCP log for the WP7 device says (MAC adress and ASG name replaced):

After that, the phone gives up. Same scenario for the Android devices.
Any idea what might happen here?
It seems that the handsets don't really receive the offered IP adress, while all other clients do.
The very same handsets work without any issues in other wireless networks.
What's additionally interesting here is:
- Android clients didn't work from the beginning of the ASG here
- WP7 worked until the WP7.5 Mango update
- The above mentioned difference between W7/Vista clients and the XP one
Seems to be somehow related to the clients' network stack.
Thanks for any ideas,
Patrick
