Hello,
Our team is interested in understanding how many OVPN/WG networks a single Pritunl host can support when using subnet sizes like /28 or /29. What factors influence this capacity?
Thank you!
The development server tests with 950 routes going over a 1000 can start to cause problems. Running sudo pritunl set vpn.lib_iptables true will use libiptables which will handle iptables rules faster to support more routes.

It remains unclear whether the problems occur when a single server has that many routes individually or when the total number of routes across all servers reaches that amount. Are these issues caused by software constraints, hardware limitations, or both? Additionally, how does running sudo pritunl set vpn.lib_iptables true help mitigate the issue?
It’s limited by the performance of the system but even a large system will begin to have issues when there are thousands of iptables rules. Using the iptables library is faster than running the iptables command, it’s had issues on some systems so it is disabled by default.

I’m using the recommended by Pritunl documentation Oracle Linux 9 in AWS should I expect issues if I use → sudo pritunl set vpn.lib_iptables true ?
No it seemed to mostly be an issue with some older systems, I haven’t seen it recently.
