Greetings, I am Mikrotik user for about 5 years approx, and is a great team but I've run into a problem that I have not been solved, anyone know how to solve really appreciate it, I will describe below what it is intended to:
There is a mail server with two network cards, one has set out to internet with IPS valid and fixed internet to send emails to the outside and the second internal network IP.
They had a linksys router that I had configured a static route pointing all traffic to go to the mail server IP was redirected to the internal network IP, and it worked properly.
Mikrotik is configured the same way that the Linksys and it do not work that was tagged on ports MANGLE mail route marks to generate traffic on the SMTP and POP Traffic this in order to tag the traffic for static routes and not duplicate routes.
and this did not work.
Also try to redirect the traffic with NAT NetMap SMTP and POP traffic to the IP address of the card's internal network server and neither worked.
Someone would know as I could do this? they would appreciate much
