Technical Service Description
- This new SSID (tufts-guest) will be "open" to wireless clients like other public wifi hotspots and registration will not be required.
- There will be no restrictions for wifi protocol, as it will offer 802.11a/b/g/n (n where available) to Guest wireless users.
- This service is intended to allow "open" client guest access, and as such there will no tie in to the TUNIS/Host Registration System to the Guest Wireless infrastructure. The wireless controllers will be directly providing IP address assignment through DHCP, and these addresses will be inaccessible in the Proteus and Host Registration systems.
- Users wishing to access secure university assets, should continue to use the Tufts full wireless service via SSID "tuftswireless".
- Since the wireless controller will be performing NAT between the client and the rest of the network including the Internet, no inbound services will be available to guest users.
- Each device will have its bandwidth limited to 5Mbps download and 1Mbps upload.
- Only a subset of IP Ports and Protocols will be allowed out the wireless controller to the rest of Tufts and the Internet (see chart).
