My first foray into a useful RouterOS script, but it was much more difficult than I expected. First off, this gitlab project pre-parses Mullvad's servers from their API on a daily basis. This is required because the entire server list surpasses the variable size limit of ROS, at least on my router. The ROS7 script, also in the repo, will then pull down files from gitlab based on the preferred countries, applies some filters, and randomly selects and sets a peer for the named wireguard interface. Testing has been limited to my preferences, so YMMV. I currently have this scheduled weekly and triggered by netwatch when pinging the SOCKS5 proxy fails.
