Thanks to everyone in advance for your assistance. The company I work has a wireless network that has two networks configured, one that connects to our domain and a guest network. The guest network doesn't have access to our domain at all so it's just internet access. The controller is an Aruba 3200XM and we have (5) AP-105's. The other day a client came in and wanted to connect back to her office via a Cisco VPN client from the guest network. She got a Cisco error message 412 and I think I figured out how to fix it but my question is is there a security risk with allowing clients to establish VPN connections while connected to our guest wireless network. Thanks again for your thoughts.
