[KLUG Members] Re: DNS and IPCop

[Tony Gettig]

Wow, I was wrong! Man, whatever you do, don't tell my wifal unit! :)

OK, I understand what you're doing and that's agreeable. But you explicitly 
configured the proxy setting. I *think*, if I recall earlier messages in this 
thread (it's getting a little difficult to follow now), he didn't want to 
configure clients to access the proxy, which would mean he wants transparent 
proxy. That being the case, web traffic is scooped off the wire by the proxy 
on its way out...transparently...so the client would have to have default 
gateway & DNS info handed to it, right? How else will it know where to go?

Otherwise, based on the results you report, I reckon default gw & DNS info are 
not required at the client. Thank you for clarifying that, because I am in the 
process of ditching squid on IPCop and running it on a different box and not 
transparently. I would have gone through the trouble of handing out that extra 
info when I didn't need to. So, thanks for saving me some effort!
