The following stuff is dead-simple in FreeBSD/ipfilter, but seems to be complex in PIX.
Because the design (no matter which brand of packet filter) applies to all IMGate/Imail 8.2x sites and will be explained later, please try to help with PIX syntax. Here are the pseudo-rules to be implemented in PIX syntax: 1. allow from any-IP to Imail-IP port 587 tcp ... is just opening PIX to allow Internet access to Imail port 587 (just like opening for port 25) 2. redirect from any-ip to Imail-IP port 25 => Imail-IP port 587 ... redirect access to Imail port 25 to port 587 Does PIX support the above and have you done it? Thanks Len
