  Yes, we did.  And it did perform much better, but it would still bog
down the network when allot of packets where trying to get through,
which is natural when several active TCP connections are being NATed.
One of the params which OpenWRT would let us tune is how long to keep
TCP NAT tunnels open, and lowering it to say, 5 minutes helped alot,
but at the same time, hurt applications which may keep a TCP
connection open for long periods in time with no activity over that
connection.  :-)

  Another thing to add is that the number of connections that the WRT
was happy with went down dramatically when VPNed into the network,
which I simply wrote off to the CPU overhead of encryption/decryption.
