If what you really mean is "behind an authenticating proxy", then it
does. It uses Microsoft's own wininet.dll, with resolution of proxy
settings determined by INTERNET_OPEN_TYPE_PRECONFIG, so if you have
configured Internet Explorer's proxy settings correctly on the local
host, then it should just work.
OTOH, if you really do mean "behind a firewall", and that is blocking
access to the required internet sites, then you will need to take the
issue up with your system administrator, because that firewall is doing
its job as configured, and there's not a lot mingw-get can do to bypass
it, if it is correctly configured.

I too have access from behind an authenticating proxy (squid). I've
never needed to set any environment variables, to kludge around proxy
settings which aren't inherited from Internet Explorer; mingw-get does
WJFFM, (discounting the occasional transient network glitch).

It should work just fine, with a properly configured proxy, when
Internet Explorer is appropriately configured for the user, on the
local host. It does WJFFM, in precisely this scenario. Thus, I have
no immediate plans to change it; if you believe you can improve it,
patches will be gratefully considered.

Were you really only trying to install libgmp-dll? Or have you elided
more of the diagnostic output than is apparent? If not, this looks
more like a transient network glitch than a proxy configuration issue.
Making mingw-get more robust, in its handling of such glitches, is one
of the many items on my to-do list. In respect of this, once again,
patches will be gratefully considered.
