One of my cow-orkers had a bright idea the other day: Simplify the configuration of tunnel configuration for Cisco routers. By entering 5 IP addresses, it would spit out configuration lines for both sides of the tunnels, auto-incrementing the IP addresses for the tunnels that were required for each line. I ended up hacking something together before coffee break and had the whole thing fine-tuned and running before afternoon coffee. Tools of choice: jQuery and plain HTML. I stayed away from the C#, VB(A), Java Struts or Perl some of my friends would use and chose (hopefully) the cleanest and quickest way.
