This role is assigned to devices unaffiliated with Ohio State but require network connectivty. These devices are not managed by Ohio State IT (Information Technology) or require little to no management. Similar to the WiFi@OSU guest network, devices assigned to this network role are effectively off the OSU network.
Network role at a glance:
- Wired connectivity only. No Wi-Fi option available
- Private IP addressing with network address translation (NAT) for all traffic
- DHCP reservations and Dynamic DNS are not supported.
- All outbound traffic permitted
- No inbound traffic permitted.
- Traffic between external devices disallowed
Network Role Characteristics
Aliases for this role include
- External
- Guest
- osu-external
Network Traffic Permissions
Outbound traffic is limited to:
- Traffic destined to endpoints outside of the external device role
No inbound traffic is permitted for this network role.
How to connect
OTDI staff must register a device’s wired MAC address, as permissions to register devices for this network role has been limited. OTDI will review each request and perform a risk assessment. If assessment passes, OTDI will register the device(s) on behalf of the requester.
Once registered, connect the device to a wired port on OTDI’s Managed Network Service.
IP (Internet Protocol) Addressing
Devices placed in the Device role are assigned private IPv4 address space dynamically assigned through DHCP. Neither IP address reservations nor Dynamic DNS is supported for this network role. All outbound traffic will have the source IP translated to routable IPv4 public address space outside of Ohio State’s traditionally assigned campus address space. However, traffic destined to Ohio State address space will retain the original private source address and not be translated. IPv6 addresses are not currently supported for this network role.
Additional Information for IT Teams
Requests for devices to be placed in this role should be submitted via the IT Service Desk. OTDI will review the request and, if approved, fulfill the request by completing the following:
- Log in to MyDevices with your administrative account (name.#a)
- Choose OSU External for the network role when registering the MAC address of the device
- Registrations will need to be renewed annually, which can be performed by simply editing the record and selecting Update to extend the expiration timestamp by one year.
