From the version 1.1, SafeFire includes experimental
transparent proxy support in NAT engine.

To use this support, add "proxy=command" lines to
your [nat] section.

This function takes command strings of the form:

  map_to <addr>[:<port>]
  [port <port>]
  [rule n]
  [proto tcp|udp]
  [src <addr>[/n]]
  [dst <addr>[/n]]
  [type encode_tcp_stream|encode_ip_hdr|no_encode]

  delete <rule number>

Subfields can be in arbitrary order.  Port numbers and addresses
must be in either numeric or symbolic form. An optional rule number
is used to control the order in which rules are searched.  If two
rules have the same number, then search order cannot be guaranteed,
and the rules should be disjoint.  If no rule number is specified,
then 0 is used, and group 0 rules are always checked before any
others.

Please notify Link Guard Solutions with successive (of failed)
usage of this feature.
