Questions and Answers about the Portable Client
Do I need to register to use DESKERIO?
No registration is required to participate in a session. All you need is one of our apps and the session PIN for the session you want to join.
To offer your customers and users support sessions via DESKERIO or to access managed devices, you must first register with us free of charge and without obligation. Your trial period begins with registration and lasts for 10 days.
Want to keep using DESKERIO after your trial? Simply choose the business plan that fits you best.
Our firewall is blocking DESKERIO. Which IP addresses are used and which ports need to be opened?
Most of the IP addresses we use are dynamically assigned and therefore only valid for a very short period of time. In addition, we operate our solution in more than 30 data centers worldwide, which means that different IPs are used in Europe than in the US or Asia, for example. For this reason, we cannot specify individual IPs or a contiguous IP range.
If your firewall supports wildcard domain filtering, you must add a filter for *.deskerio.com and allow incoming and outgoing traffic.
Our native and browser-based applications always use TCP port 443 (https) to communicate with our servers. If the servers cannot be reached this way, the native apps will alternatively attempt to connect via the following ports in the order specified here:
- 8443
- 2053
- 2083
- 2087
- 2096
If port 443 is blocked or otherwise restricted in a network environment, it is usually sufficient to open one of the above TCP ports in the firewall for outgoing traffic.
