This is the output of curl command:
curl -v download.fedora.redhat.com
* getaddrinfo(3) failed for download.fedora.redhat.com:80
* Couldn't resolve host 'download.fedora.redhat.com'
* Closing connection #0
curl: (6) Couldn't resolve host 'download.fedora.redhat.com'
This is my iptables file, where eth0 is the internal network and eth1 is
the external network to ADSL modem

Reassuming:
1) synaptic is working and all network including router
2) websurfing and e-mail are o.k on all network
3) yum, wget, curl work fine on all network with the exclusion of the router
Where is my mistake on iptables??? Please note that I am using a trasnparent proxy running on same router (Squid)
