Product and Software: This article applies toall Aruba controllers that run ArubaOS 5.x and later.


The Virtual Internet Access (VIA) client is used to access enterprise networks across the WAN. When a user tries to establish a connection to the controller across the WAN, usually a firewall filters the traffic.


In this case, certain ports must be enabled on the firewall to establish a secure connection.


To establish a VIA connection through the firewall, these ports must be allowed:


For Windows client

TCP: Port 443

UDP: Port 4500


For MAC OS client

UDP: Ports 500, 1701, and 4500

TCP: 1723, 443

IP protocol: 50 (MAC OS has a different IP stack, so you must enable more ports.)


For detailed information about setting up the VIA client, see the ArubaOS 6.1 User Guide, chapter 18.
