I’m all about saving time especially with this useful VPN profiler. My more ‘techy-for-the-sake-of-it-chums’ will say the following is cheating, and your ‘not a technical super-god unless your wading in line after line of code’. I however, argue if you had a job you’d worry about time instead of technical bragging rights, so below is a very useful spread sheet which let’s you put in your plain English VPN IPsec requirements for a router > router connection, and it will generate the appropriate config for you, you can cut & paste into IOS. You need to specify things such as IP address ranges at both ends and such like, but its a very quick way of building a working tunnel.
So download the Spreadsheet and get going – its awesome. The file is also available via ‘MariosCloud’ (here)
