Thanks for responding. I will have a look at the script and see if that helps. We are already using some software called captivate by the same company to get the SecureNAT clients to authenticate before they access the Internet. I had a look at what devices were using the guest network and only about 13% were running Android. My understanding is that it's only Ice Cream Sandwich that supports proxy settings on Android or have you found that earlier versions allow users to put in Proxy info? Cheers.

We have a similar problem with TMG acting as a transparent proxy for our guest wifi. We have a direct Internet connection so don't have any of the upstream issues that some are facing but still have an issue with SecureNAT clients accessing secure websites. http works fine. I wonder if Jamesfed or Jwood or anyone else who has this sorted are able to offer any assistance on this? We're beginning to think that we will have to require clients to enter proxy settings which as far as I can see would mean that Android users wouldn't be able to use the wifi. Many thanks, Richard
