Pierre, remember to send your replies to the list, not the user.

Ping looks right.

Wget seems also right. It fetches the file, so please, open that file
and tell us what are you seeing.

Dig resolver the domain fine. Mmm, wait... wait a minute.

Oops, something is wrong here. We are getting different output for the

Let's carefully examine this.
First, www.debian.org has the following addresses:
sm01@stt008:~$ host -t a www.debian.org
www.debian.org has address 194.109.137.218
www.debian.org has address 213.129.232.18
www.debian.org has address 141.76.2.5
So... *how* and *from where* are you getting "61.5.210.7"? I can be
wrong, but that IP does not look to be a Debian host, but a download
mirror:
sm01@stt008:~$ host 61.5.210.7
7.210.5.61.in-addr.arpa domain name pointer depot.nautile.nc.
Compare with my traceroute:

Which looks more normal.
> Still unable to use web browser to go to www.debian.org without proxy
Yes, because you are being redirected to an "unknow"? host :-?
A quick try: use openDNS dns servers instead your router's ones.
