Before you can connect to SeRP via VMware Horizon, you may need to ask your organisation's IT team to allow the connection.

The outbound ports required are:

  • 443 TCP (https)
  • 4172 TCP & UDP
  • 8443 TCP & UDP

The Horizon client will need to be able to connect to:

  • https://connect.serp.ac.uk
  • alpha.connect.serp.ac.uk
  • beta.connect.serp.ac.uk
  • gamma.connect.serp.ac.uk
  • delta.connect.serp.ac.uk
  • 137.44.141.60/30

HTTP(s) traffic can be via a proxy as long as HTTPS inspection (man in the middle) is not used.
