Hello, i have a debian (etch) server/firewall with dhcp-server and iptables with eth3 connectet to a switch, and a Laptop without Batterypack and without any Harddisk, USB-Stick or whatever can store Information, also connected to that switch, no other computer is connect to that switch. -I've set the default policy of both ipv4 and ipv6 for all chains to DROP (debian server) -there is no rule specified -the dhcp-server is configured (by MAC) to delivery the ip xx.xx.xx.34 to the Laptop -the Laptop has a DVD-drive with a Knoppix-Distribution configured to use DHCP if i boot the Laptop, there are 4 Packet registered to be dropped by the INPUT-default-policy, but the Laptop gets the ip-address. In the syslog of the server, there are entries from the dhcp-deamon for the request and the answers., but the OUTPUT - chain - Packet-Counter is already at 0. How are the packets (i thought it would be UDP) transmitted.
