One step at a time. Can you change the subnet from 172.60.0.0/24 to 172.16.0.0/24?
To do this, you can either enter configure mode and change every appropriate spot or you can use a text editor and replace 172.60 with 172.16 everywhere and then use the load command in configure mode to load the edited file. In either case you have to commit afterwards and save. Probably should use commit-confirm to make sure things work. And backup current config first by doing something like
save config.boot.backup
which will be written in your /config dir.
Then read my earlier post about web servers about 10 posts up.
