HighSide was built by design without the need to support proxies given that the platform fully encrypts all data being sent on the local endpoint before it even touches a network, so proxies for the purpose of inspecting data, would find no use with HighSide. As such, HighSide does not currently support proxies. For US SAAS users, HighSide currently recommends that clients add a rule into their firewall/proxy that allows traffic in and out based on the following ports and protocols: 

  1. highside.io 
  2. relayproduction.highside.io
  3. maps.googleapis.com.

These servers do not have static IP's, all of the above connections should be allowed on port 443.

*Note* Google Maps is only used when admins are creating location restrictions for a user group, Google Maps is not used anywhere else

Also note that HighSide uses a self signed certificate so if your network has self signed certificates block you may need to file for an exception to use HighSide.

 

HighSide's Voice and Video system also uses some specific ports that are listed below:

Port 80 over TCP is used for SSL certificate verification

Port 443 over TCP is used for general connection (Should already be allowed as stated above)

Port 10000 over UDP is used for general network audio/video meetings

You may also need 5349 TCP - for fallback network video/audio communications over TCP if the initial connection is blocked.

 

For users that may be using our European or UK data center, you'll need to whitelist these URL's instead of the normal relayproduction URL:

UK: relay.uk.highside.io

EU: relay.europe.highside.io
