Feeling thick: Smoothwall Transparent Proxy
SWG-1200, Guardian 3, updated to main 68.
I always got the idea that all I had to do for guest access via SSL login page was:
* Plug in a second network port, give it an address in the guest VLAN
* Set the default gateway of devices to this IP
* Set up a transparent auth policy for all traffic coming in to this NIC for SSL Login page
I cannot get anywhere though.
The SSL Login page works on my normal range if I set it on a different proxy port (I don't want to break lots of things by testing transparent here though).
The laptop I'm testing with can ping the Smoothwall IP, that is set as default gateway (all this is done statically for now)
But when I try and load any page, nothing happens. Fiddler is telling me that requests are bouncing with 502, Failed DNS lookup. I've tried setting DNS to Google's servers, our ISPs servers, even to the Smoothwall IP, but nothing.
What am I missing? Do I need DNS setting up internally to this range as well? Or is transparent proxy for guest access inherently undoable on an SWG device and I'll be forced into paying the big fat upgrade fee for a UTM device?
