Greetings, I have a Netgear switch that is unable to acquire a DHCP lease. The DHCP discover request is not replied according to dnsmasq & tcpdump log. I guess the UDP src ip is a violation of the RFC.
11:26:06.106723 IP (tos 0x0, ttl 64, id 380, offset 0, flags [none], proto UDP (17), length 281) 192.168.0.239.68 > 255.255.255.255.67: [udp sum ok] BOOTP/DHCP, Request from 74:44:01:78:e1:ed, length 253, xid 0x8274d270, Flags [Broadcast] (0x8000) Client-Ethernet-Address 74:44:01:78:e1:ed Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Discover MSZ Option 57, length 2: 576 Parameter-Request Option 55, length 3: Subnet-Mask, Default-Gateway, Domain-Name-Server If I add a route for this IP range on the server the problem is fixed. sudo route add -net 192.168.0.0 netmask 255.255.255.0 dev vlan20 Shouldn't the broadcast flag in the DHCP request take care of this situation? Thank you for your assistance. _______________________________________________ Dnsmasq-discuss mailing list [email protected] http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
