Hello experts - I recently assumed additional responsibilities at work which include all switching and routing. I'm not an expert (yet) so could use some help in getting started troubleshooting a particular issue. I am attempting to setup a private wireless network that will connect Apple devices to my LAN for access to email and RDP. Its 90% there, the only remaining issue is that users on the wireless network can't access https sites which run on it. Going out to the internet works fine with https, its just internally where the sites won't load. The configuration is setup where the wireless access points are connected to a 2504 controller. This is attached to a 4510 switch as is the 2811 router (gateway) and 5510 ASA (firewall). In this case I believe the problem is on the router or switch since requests for internal sites shouldn't be routed to the ASA.
That is where I'm stuck. I am not certain how best to troubleshoot access issues like this between devices. I would appreciate any tips or advice to get me going, thanks!
