Updates for style

I updated the script a bit for myself, thought I'd contribute back.

Since the idea is to use this on a new (and ephemeral) server, it doesn't make much sense to take caution not to nuke existing files.

The only useful change is pushing down the route explicitly rather than relying on `def1`, and switching to TCP 80 since I ran into issues in Korea at COEX connecting via UDP 80.
