Hello again, 
 
as I wrote in my last mail, I'm trying to use Dnsmasq on an Intel 
IXDPG425-Platform, which is running with a 2.6.11.2 Kernel, using GCC 
3.3.4 and GLIBC 2.3.2.  
 
Both funtions, DHCP and DNS-Forwarding doens't really work. 
When starting Dnsmasq on the IXP and trying to get an IP-adress for the 
client, the following messages appear: 
 
root at ixp425:/etc# dnsmasq -C /etc/dnsmasq.conf -q -K -d 
dnsmasq: started, version 2.22 cachesize 150 
dnsmasq: DHCP, IP range 192.168.1.100 -- 192.168.1.200, lease time 2h 
dnsmasq: read /etc/hosts - 2 addresses 
dnsmasq: reading /etc/resolv.conf 
dnsmasq: using nameserver 217.237.151.97#53

dnsmasq: DHCPOFFER(ath0) 192.168.1.178 00:0f:3d:ad:42:a3 
 
TCPDUMP shows this:

When using ICS DHCPD instead of Dnsmasq, everything works fine. 
 
The DNS-Function in Dnsmasq doesn't even react on incoming packages...a 
dig at server shows a timeout (the domain and bootps-ports are running on 
server). 
 
Hopefully, someone can help me to solve these problems... 
 
Thanks and Greetings 
Daniel
