Normally, I would agree. However, in this case, the environment is an existing one that I do not want to tamper with for technical reasons (temperamental enough as is).
My only option is to setup as outlined. Thanks, Danny -----Original Message----- From: Steve Leach [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 10, 2003 12:18 PM To: Cox, Danny H. Cc: [EMAIL PROTECTED] Subject: Re: [gb-users] Port translation? Danny, Without trying to be clever (and not understanding how your setup is put together), would it not be better if the application sat on port 25 - despammed etc, and then sent to itself on the loopback interface 127.0.0.1:1234 ? That way you collect all traffic coming into the server from inside or outside, and also can submit to a 'known good IP:port'. -- Best Regards, Steve Leach Network Manager MI International Ltd DISCLAIMER Any opinions expressed in this e-mail are those of the individual and not necessarily of MI International Ltd.
