Public Use VLAN (x-posted to security listserv)
As much as I hate it, I’ve been told to setup an open wireless network for our campus. I created a vlan with access lists that deny all traffic to inside our network, and created the open SSID to put on it. Traffic can flow freely now from the open wireless to the internet.
However, I’m using a public DNS for the clients and they’re unable to reach our locally hosted (NAT’d) web servers. We’re currently using a Cisco ASA at the edge of our network which does all of our NAT’ing. I could open up the VLAN access list a bit and allow them access to our internal DNS & web servers, but I’d rather not.
Has anyone run into this issue before? What’s the “best practices” at this point… other than removing the public network in the first place!
Thanks in advance,
