I'm trying to use the Helpdesk function of Horizon, in particular the Remote Assistance function. We have a fairly complicated network setup with the view desktops on a private LAN, the connection servers on a production LAN public IP range and and connections to desktops being served via an F5 appliance.Then my desktop that i want to do the remote assistance from is on another public IP range. I am looking to see which ports i need to get opened in the firewall. I found a Microsoft article which says the following but does it really need every TCP port higher than 1024 opening?? Not sure my network guy will handle that well!
Remote assistance relies on full network connectivity between the expert user's computer and the novice user's computer over the following network ports:
- TCP port 135
- TCP port 3389
- All TCP ports that are greater than 1024
If port filtering exists for any of these ports between the two computers, Remote Assistance will not work.
