Hi ! I want to inform you that i have discover a bug with 802.1Q technologie and SQUID.
802.1Q is for VLAN's : the module 8021Q is use to configure a network card to be present on different VLAN's (tagged port). My previous installation was : VLAN 3 on eth0 10.0.0.0/255.254.0.0 routeur SDSL (gateway) 10.0.0.1 VLAN 2 on eth0.2 (vconfig add eth0 2) 10.20.0.0/255.255.0.0 VLAN 1 on eth0.1 (vconfig add eth0 1) 10.10.0.0/255.255.0.0 With this configuration, i was ending weirds issues : i was not able to log in hotmail, yahoo!mail, e-bay, or perform any transaction on net. For exemple, with hotmail, the https transaction was done and recorded on log, but the following url was not recorded in log and a basic error message prompt on navigator (DNS error or serveur not found). By despair, I change my network conf to use a different networdk card for each VLAN and it's finally works. So, don't use 8021Q module with SQUID ! NOTE : I use 8021Q for my data serveur (SAMBA and netatalk) and it works fine
