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
