[squid-users] Not reaching one site

Hello everybody.

I'm experiencing strange error happening with my transparent proxy
setup. I'm not able to access the domain debian.org. Here's what I got
from my proxy:

proxy:~# ifconfig | grep "inet addr:"
          inet addr:172.16.16.1 Bcast:172.16.16.255 Mask:255.255.255.0
          inet addr:192.168.1.253 Bcast:192.168.1.255
Mask:255.255.255.0

My LAN is 172.16.16.0/24.

proxy:~# nslookup debian.org
Server: 172.16.16.254
Address: 172.16.16.254#53

Non-authoritative answer:
Name: debian.org
Address: 128.31.0.51
Name: debian.org
Address: 206.12.19.7

The first thing I noticed, was that I am using my LAN DNS to resolve
hostnames, which I think is not quite the best solution. Thus I changed
it to use my router's DNS (192.168.1.254):

proxy:~# nslookup debian.org
Server: 192.168.1.254
Address: 192.168.1.254#53

Non-authoritative answer:
Name: debian.org
Address: 206.12.19.7
Name: debian.org
Address: 128.31.0.51

In both cases, when I use my browser in my LAN (whichever PC I use), I
get:

(101) Network is unreachable

Squid logs shows in access.log:

What could my problem be and how may I resolve it?

Thanks and kind regards.
