Because Mikrotik routers behave a bit different than the usual TP-Link, GL.iNet etc. devices and because there were some pitfalls I had to master myself, here’s some advice to keep… Continue reading Bringing OpenWrt to the Mikrotik hAP lite (RB941-2nD-TC)

For instance, you might have tightened down network access to secure a local CA. Or, like me, you have a Raspberry Pi that you carried around with you… Continue reading Using a reverse SSH tunnel to provide an isolated system such as a Raspberry Pi with network access (well, HTTP)
