Scriptlet: Bulk VPN connections on MikroTik with connection rate limiting

During my day job we use some MikroTik CHR deployments for (among other things) VPN session termination. The CHR’s are easy to spin up, offer a wide variety of VPN types, and for low traffic sessions can support upwards of 10,000 sessions on a single device.

It’s over 9000!

In the event of an outage though, you would run into a problem – those 10,000 sessions all want to re-establish at once.. and the CPU on the MikroTik quickly bottlenecks until it becomes unable to cope and begins to drop connections quickly becoming a vicious cycle.

We initially dealt with this by defining a hard limit on the number of new sessions per second, using 2 simple firewall rules and the connection limit classifier to keep these under 10 per second – however this meant that after an outage it would take at absolute minimum, over 15 minutes for all the sessions to come back online! So we came up with a better solution. Continue reading Scriptlet: Bulk VPN connections on MikroTik with connection rate limiting
