OpenBSD has relayd(8), a versatile tool which can be used here.
There is support for proxying TCP connections. These can be modified
in a few ways - socket options (nodelay, sack, socket buffer) can
be adjusted on the relayed connection, also SSL can be offloaded.
It works with the firewall state table and can retain the original
addresses. Parts of this are only in development snapshots at present
but will be in the 4.4 release.
