Nokia Software Updater: Will it work under Proxy Server LAN Settings?

Hi there,

I want to update my N70's firmware to the latest one. Right now my
mobiles firmware is V 5.0616.2.0.3 (used the *#0000# to retrieve it).
I've installed the Nokia Software Updater v1.1.27en on my system. My
internet connection is not a direct LAN connection, there is a Proxy
server/Firewall.

Now my question is whether with this setup I can update my phone's
firmware?
