When trying to convert an 1142 AP from LAP to Autonomous AP, I did a mistake. I copied the new IOS (.tar) with the ‘copy’-command. However, I should’ve used the ‘archive /xtract’-command. When I reloaded, the AP presented me with this;

Tired of having a Cisco-device that always ends up with a wrong clock? I was.
The first thing you’ll need, is a proper NTP-server. You can either set up one locally (which syncs from a hardware-device ? like a GPS ? or from an external server), or you can choose one of the public available NTP-servers. I’ve chosen to use ?126.96.36.199? in this example.
Up until recently, I’ve had ADSL at home for some years. For the last year or so, I’ve used a Cisco 1812 as my router (the ISP-router was put into bridge-mode). A few weeks ago, when I got a 10/10Mbps fiber-connection, it suddenly became more relevant to host some services at home (why pay for web-hosting, when you can host it home, for free?). As a result of this, I stumbled upon a “problem” that annoyed me a bit; loopback-support – the ability to reach your services using your external IP, and hence applying port-forwards (this way you could use
ssh externalip -p "some odd port number" regardless if you are home or not). This is quite useful if you move between different networks a lot (e.g. using a laptop – which was the case for me). This feature is known as tromboning, or hairpinning, and is something that often works on cheap routers you get from your ISP. So, why shouldn’t this work on a Cisco-device?
