Pix and MCIS service

I have several SMTP services running on the same Server using MCIS. Therefore, there are SMTP services listening non-standard port (25). If I want to send a mail from one server to the other I cannot use the public address (the PIX does not allow it). The problem is that if you configure everything so that the connection goes to the private IP (192.168.x.y) it goes to the standard SMTP port. Is there any way to solve this?

Would it work to use something like this...?

static(inside,inside) tcp OUTSIDE_ADDRESS 5001 INSIDE_ADDRESS smtp netmask

Re: Pix and MCIS service

Yes, you can map ports to the same host or different hosts internally.

> static (inside,outside) tcp 5001 smtp

> static (inside,outside) tcp 5002 2001

> static (inside,outside) tcp 5003 2002

> static (inside,outside) tcp 5004 2003

You can't map the smtp pot to more than one internal port, but as long as all your port numbers are different then you should be fine. The can also be the keyword "interface" to map them to the PIX's outside interface IP address.
