SubjectDHCP and iptables
Hi,

The last few days I have been wondering about the fact, that I get an IP
address via
DHCP if all chains at iptables are set to drop and no accept rules set.

Does this happen on purpose?

I checked twice, if I really get an IP from my DHCP-server, checked the DHCP-
messages and a wireshark trace.

I Also tried the check_dhcp-nagios plugin, which fails if I do not allow
packets for the input chain, destination port 68, protocol udp.


Why do I get an IP address, if I drop everything?

Sincerely yours Mathias Kub
