If you can give priority to (remote) IP address ranges, instead of port numbers, that would be more reliable. Among other less safe VPN protocols, we also have TCP port 21, TCP port 23, TCP/UDP port 53, TCP port 80, TCP port 1080, and TCP port 4444. Hopefully, you can specify port ranges, and not just individual port numbers. We use a fixed range of ports (15000.52500) on our race servers.

There is not much you will be able to do with that, since most programs do this same thing.

This means that your computer finds an unused port number, and uses it for its end of the connection. We use "ephemeral" ports on the local end. If you have a different answer for this question, then please use the Your Answer form at the bottom of the page instead. Help to improve this answer by adding a comment. There are two ends to each communication: the local end (your computer), and the server end (our server). Basically you need ports 99 or a subselection of these depending on your systemnumber (s). The sim uses only UDP traffic, so if the others using your Internet connection are using mostly TCP, and you can give priority to UDP traffic, that would be an easy first step. If TCP fails on 55754, 55752 with HTTP is used for application data (AES encryption). Used for video, audio, metadata stream (AES encryption). That’s the reason why commercial VPN services typically no longer offer this protocol anymore.Solution home Issues and Error Messages Connection What ports and IP addresses does iRacing use? Used to discover AXIS Camera Station servers with SSDP (UPNP). And since the PPTP protocol has been in use for several decades now, it has already shown its vulnerabilities. These require special configuration of firewalls for proper implementation. Then, we have the PPTP protocol, which uses ports 1723 through 1729. Still, keep in mind that IKE is quite often combined with the IPsec protocol, which provides the highest possible level of commercially available encryption, which makes those connections highly secure. This is one of the most widely used ports in the world of online networking, which makes it vulnerable. When it comes to the IKE (Internet Key Exchange) protocol, you can see above that it uses port 500. Still, there are some ports that VPNs typically avoid using. Of course, not every port is equally safe – even though the level of encryption we get today is practically uncrackable. Which Ports Aren’t Safe for Use via VPNs?
