Hello,

I've set up my domUs to get their IP address through DHCP from a dhcpd in dom0. At boot they send DHCPDISCOVER to the broadcast address, dhcpd answers without any problem, but when they try to renew it - sending DHCPREQUEST to a unicast address, dhcpd logs bad udp checksums and refuses to answer. Checking the packets with ethereal shows the same, other UDP (like DNS) and TCP works fine through the bridge and way out. I'm using xen-unstable, checked out on 09/18. How can this be avoided?

Regards,
Zoltan HERPAI
