Dear all, Trying to explain my problem: I've Linux Mandrake 8.0 I use iptables for filtering but this problem still exist with transforming my linux box in a client of a network: i can ping 193.252.19.189 but not www.wanadoo.fr i can dig or nslookup www.wanadoo.fr which reports me 193.252.19.189 of course while i'm doing http://193.252.19.189 everythings works fine but http://www.wanadoo.fr not. my nameservers are OK ( 193.252.19.3 and .4 in resolv.conf) I dumped the tcpdump result which give me a udp port unreachable: (FJT hostname of my linuxbox, 192.168.01 is my gateway) 09:59:18.882158 FJT.32859 > 193.252.19.3.domain: 32456+ A? www.wanadoo.fr.
