I don't know about HSDPA; with EVDO, my connection will drop if the
machine tries to emit packets with the "wrong" source address. (This
is apparently in the EVDO spec.) So -- a connection drops, I dial
back, open TCP sessions resend, causing the connection to drop, ad
Instead, I have an ip-up script that creates an IPF filter to block all
other packets from the link; this is removed via ip-down. It's worked
quite well. You may want to investigate that option.
