Squid - select loopback interface or not?

 IIRC you need the loopback interface selected for Lightsquid to work.

 @KOM: IIRC you need the loopback interface selected for Lightsquid to work. ok only for lightsquid. And if i wanna use squidguard….Do i have to turn loopback device also on ? 
- 
 Not sure. I'd just leave loopback selected unless it's giving you some specific problem.

 @KOM: Not sure. I'd just leave loopback selected unless it's giving you some specific problem. Ok. Thx. Is loopback necessary for clam (antivirus) ? 
- 
 Definitely no idea. I don't run that crap on my router. AV belongs on the client, not the router.

 Thx KOM….you helped me and a lot of other users in this forum. :-)

 I found a difference when I activate loopback interface in proxy mode. if the loopback interface is activated, advertising links on google search results won´t open. thats great! 
 if i deactivate the loopback interface, advertising links on google search results open again..can someone explain why it is like that? thx

 Perhaps the loopback interface is used by squidguard? 
- 
 no

 It's now a week later and you're still worrying about this? Stuff works when it's selected, stuff breaks when it isn't. Just leave it selected.
