This is not the right way to go about it.

Mark packets coming in over the internet with either ipchains or netfilter.
This needs 'shape on fwmark' or something like that enabled in the kernel
configuration.

If the packets traverse your router untouched (ie, don't go via the proxy),
the mark will remain on them. Then you shape outgoing packets in eth0 that
have this mark on them, and don't shape other packets.
