Watchguard Firebox M200: Unblocking WeTransfer

If you are blocking “Personal Network Storage and Backup” at your Watchguard Firewall, users won’t be able to access wetransfer.com. In their own support documentation here, WeTransfer suggested creating the following firewall exceptions:

*.wetransfer.com

*.we.tl

*.amazonaws.com

*.wetransfer.net

However, this still doesn’t prevent the Firebox from dropping the traffic. Below is a table of exceptions I had to create to get things working properly.

Wetransfer #1 Pattern Match *.wetransfer.com/*
Wetransfer #2 Pattern Match wetransfer.com/*
Wetransfer #3 Pattern Match *.we.tl/*
Wetransfer #4 Pattern Match we.tl/*
Wetransfer #5 Pattern Match *.wetransfer.net/*
Wetransfer #6 Pattern Match wetransfer.net/*
Wetransfer #7 Pattern Match *.amazonaws.com/*

Using Regular Expressions, this can be simplified further:

Wetransfer #1 Regular Expression (wetransfer\.((com)|(net)))
Wetransfer #2 Regular Expression (^we.tl)|(\.we\.tl)
Wetransfer #3 Pattern Match *.amazonaws.com/*
