hello there guys!
i have a bit of a problem here..
i've been using IP masquerading for a while now, and it all worked
perfectly until last saturday...
that's when the company it people decided to change the firewall rules
and don't accept requests with source ports as high as 60000 ( read IP
masquerading... ;-) ).
so now, i'm faced with the problem... people can't read email anymore...
the company is divided in different countries, and everybody gets their
email via POP3.
but now the network firewall in New York does not let people inside my
network ( in brazil ) connect to the mail server, since the connections
are comming from the linux box i've set up to be the gateway with src
port > 60000.
can anyone please explain to me, how to configure the linux box so the
requests are to be made from the same port as the destination?
like this...
192.168.0.1 ----> linux box ---> email server
office win95 RH 5.2 WinNT
the request must come from the linux box to the mail server with the
same destination port, as if in a normal connection.
the gateway box is ONLY for gateway purposes... the only ports that it
listens to is 22 ( SSH ) and 53 (domain).
i really need an answer from you asap... please!
i have a bunch of directors trying to kill me because they can't get
email!!!! ;-)
thanx so much for your help!
in case you have any doubts bout what i just explained please contact me
directly by email:

thanx again!
