I'm trying to setup a captive portal using this guide by andybev.com. I would like for my router to forward www traffic to my captive portal server for authentication. I found this article on SSG TCP Redirect Access Control List, but from the looks of it my IOS doesn't support this feature. So I was wondering what would be the best way to forward that traffic to the captive portal? Below list the info on my router and the IOS
