No INcoming mail

OldSchool
I do not have the SMTP proxy option, so I want just be able to open smtp port (25) on the UTM 425 and send mail straight through to my exchange 2003 server. I can send mail out of that server, ever mail that is coming in it port blocked, the live log show everything is red, therefore being dropped out. 

I have made rules to allow email traffic, and smtp traffic to my inter IP email server. 

any ideas?

    Hi, OldSchool, and welcome to the User BB!

    Also, in a NAT rule, it's a good habit to leave a field blank if not changing it.  In this case, since it's a single service with a single destination port, there's no problem.

    Cheers - Bob

    And one other note -- if you did not check the automatic packet filter checkbox on your corrected (as the others pointed out, your rule was incorrect) DNAT rule, you will need to create an inbound SMTP Firewall rule as well --- note that Firewall Rules are applied after NAT operations, so it would defined as  Internet (or ANY) -> SMTP -> .
