Rooted/Custom ROM Android devices can have real iptables running. You
need a kernel with netfilter obviously which some OEM kernels won't
have but most Cyanogenmod ROMs should. There's an App called DroidWall
(http://code.google.com/p/droidwall/) that acts as a GUI for iptables
and it's open source so you can just see it running a bunch of
customised shell scripts:

Stock Android also supports HTTP proxies through the Access Point
Names settings (although that wouldn't affect wifi). There are
existing apps to run proxies on the device that alter user agents in
this way http://www.androidsoftware.us/Applications/Filter-Proxy.html
