Yes, I've already said that, but.... you are great! ;-) I read your message this morning quickly, when I was going to work, and didn'understand it. Then I've spoken to a colleague of mine, a true network guru, a very capable ethical hacker, and I've understood! (I suppose....) My wireless router: a) runs a (WAN) DHCP client to get its IP address and the IP addresses of my provider's nameservers; b) it get those IP addresses to send them to me when I run a DHCP client; my wireless router runs a (LAN) DHCP server too, but it is *not* a nameserver; c) my DHCP client was configured as usual, i.e. "replace my /etc/resolv.conf"; I've added dhcpcd_toynet="-R -h sergio" ^^ to /etc/conf.d/wireless and restarted /etc/init.d/net.wlan0. Now... there is no line "nameserver 192.168.2.1" in my /etc/resolv.conf and ping www.google.com is fast ;-) BTW: This evening I've started running Windows at first. ipconfig /all showed three nameservers, and 192.168.2.1 was the first one. However, when I ran nslookup, the message was clear: 192.168.2.1 is not a nameserver. Why the difference between fast (Windows) and slow (my previous Gentoo box) Internet pings? Perhaps because the Windows timeout is short: 2 seconds. I do not know how to eventually set such a timeout in Linux.... > Second, does "ping -I wlan0 192.168.2.1" work better? Nope. ping <-I wlan0 or -n> 192.168.2.1 is still blocked. Well, it's just a nuisance, but I'll keep looking for a solution. Any hints would be greately appreciated ;-) That's not strange, because: sergio ~ # nmap -sS -O -PI -PT 192.168.2.1 Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2006-11-28 22:21 CET Interesting ports on 192.168.2.1: Not shown: 1678 closed ports PORT STATE SERVICE 80/tcp open http 4662/tcp filtered edonkey MAC Address: 00:17:3F:0C:19:12 (Belkin) Device type: broadband router Running: Netgear embedded OS details: Netgear Wireless router or Netgear FM114P/REPOTEC IP515H Router & Print Server Nmap finished: 1 IP address (1 host up) scanned in 4.834 seconds i.e., port 7 (Echo) looks closed.

I wish to configure my real (wire and wireless connection to my ISP) and virtual (VMWare) networks, and then enable iptables. Thanks a lot, as usual ;-) Sergio PS: I wish to thank Thomas Sjolshagen (private message) and Hans de Hartog too. If one doesn't feel lonely when he tries to solve a problem, well.... that helps a lot! My English is poor, but I hope that you understand what I mean ;-) -- gentoo-user@gentoo.org mailing list
