67534b228a Allow PacketAliasSetTarget() to be passed the following:
INADDR_NONE:   Incoming packets go to the alias address (the default)
  INADDR_ANY:    Incoming packets are not NAT'd (direct access to the
                 internal network from outside)
  anything else: Incoming packets go to the specified address

Change a few inaddr::s_addr == 0 to inaddr::s_addr == INADDR_ANY
while I'm there.

942ce5d318 When an incoming packet is received that is not specifically
redirected and when no target address has been specified, NAT
the destination address to the alias address rather than
allowing people direct access to your internal network from
outside.

d8acaf9b94 Properly handle the case when either the aliasing or source address of
the link are equal to the default aliasing address.  Do not zero them!

This will fix the problem with non-working links added with the source
and/or aliasing address equal to the default aliasing address, but the
default aliasing address is set later, after the link has been set up,
like both natd(8) and ppp(8) do (for objective reasons).

fbd7c04554 ReLink() partial links in FindLinkOut() in the same manner as we do it
in FindLinkIn().  This will make TcpMonitorIn()/TcpMonitorOut() happy.

ad9a3de54d Restore previous version of FindLinkIn().
Instead, natd(8) should be fixed to call PacketAliasSetAddress()
as part of initialization, as required by libalias(3).

eb97f5a4de - Make partially specified permanent links (without `dst_addr' and/or
`dst_port') work for outgoing packets.

- Make permanent links whose `alias_addr' matches the primary aliasing
  address `aliasAddress' work for incoming packets.

- Typo fixes.

e33f0286b1 1) in CleanupAliasData, don't nullify entry in linkTableOut
since there might be permanent entries still left after
   calls to DeleteLink (it will be nullified by DeleteLink
   if all entries are deleted, won't it ?)

2) in PacketAliasSetAddress, set the aliasing address
   even when PKT_ALIAS_RESET_ON_ADDR_CHANGE is in effect.
   Just don't clean up links in this case.

cf067e235a Create the alias library. This is currently only used by
ppp (or will be shortly).  Natd can now be updated to use
this library rather than carrying its own version of the code.
