It can - depending on how broken the "firewall" :-)

You can use nicer and safer url like:

http://www.mydomain.com/update/123456

On the server side, you configure the server to handle any url that 
starts with /update with the script update.php. If the url has one 
path component, treat it like the serial number. If not, return 404.

This way you can also change your implementation later (e.g. replace 
with a Python or Ruby script) without changing the interface for the 
clients.
