The masqd code now works. It passes the packet to PacketAlias{In|Out}()
with a potentially zero'd ip_sum (PacketAliasIn() packets) and recomputes
a zero sum afterwards. The only other thing needed was a call to
SetAliasAddress().
Any feedback from people would be great - the code can be found on
www.awfulhak.demon.co.uk.
Perhaps it might be a good idea to make an "alias" library out of this stuff,
that way, it can be ported to different environments easily. So far, the
code written is rather trivial - it screams to be a library !
I'll write again when I've polished the code (and maybe written a man page).
I havn't seen the natd code yet - I've seen reports that it's difficult to
get to the web page it's on ;( However, I like masqd hugely as it's so
simple.
