It is TCP to port 80, but that is all. There is no HTTP GET request. Another surprising thing was that there are many TFTP file transfers. I have expect HTTP transfers. The answers might be in the DHCP OFFER which says "server name 'dhcp209'", but no DHCP option 209. I would like to see the dhcp server configuration file. And I do like to read in the discussion order ( reply below the text ) Groeten Geert Stappers -- Leven en laten leven

Eth0 -public, Eth1-Private. Eth1 is 192.168.0.100 and dhcpd is tied only to Eth1. I just realized the /etc/hosts has dhcp209 pointed to Eth0's IP address. Hope now this is not a major issue. Everything has been always like this on tftp/dhcp server.
