VPN connection EUR
Description of the service
Via the university network (EURnet), Erasmus University Rotterdam offers various services reserved for staff and students of EUR. Services from outside the EUR network are sometimes not available. This particularly applies, for example, to consulting various information databases of the Library.
To enable staff and students to utilize these facilities via the public Internet a VPN network network connection can be used . By establishing a VPN connection to EUR, the computer becomes a component of the EUR network as it were, enabling use of non-public services.
Instruction manuals (for PPTP)

Please notice: from Mac-OS Sierra it is no longer possible to create a VPN connection using the PPTP protocol (the PPTP protocol is still available in Mac-OS El Capitan and lower). As an alternative for Mac Sierra users, please use EZProxy
Firewall or Router Configuation
If you use a personal firewall or a broadband router, or if there are routers or firewalls between the VPN client and the VPN server, the following ports and protocol must be enabled:
- Client ports: 1024-65535/TCP
- Server port: 1723/TCP
- Protocol: PPTP
- Enable: IP PROTOCOL 47 (GRE)
For information about your firewall or router configuration, and to confirm that your firewall or your router will pass these ports and protocol, contact the manufacturer of your device or your VPN server administrator.
The ERNA-VPN service is based on technology that enables users to establish a secure connection (a so-called secure tunnel) to the university network (EURnet). The security is attained by authenticated users (based on ERNA user names and passwords) before establishing the connection. Further, there are safeguards to ensure that all data exchanged with individual users are keyed to a level of security whereby, in principle, eavesdropping or hacking of connections is not possible.
Through the VPN connection, the response times for slower connections will be slightly poorer. We therefore recommend use of the VPN connection only when necessary. In a technical sense, users appear to be working with or from an EUR IP address. You should make allowances for the fact that you may not be able to utilize some (protected) services of your own provider, if you have an open VPN connection to the EURnet.
The regulation "Use policy for computer and network facilities of the Erasmus University" applies to the use of the aforementioned facilities. In perspective of this, you should explicitly make sure that you have installed anti-virus software on your computer. Please refer to the manuals for other uses and preconditions.
