Mail Server behind pfsense

[j90785859]

Hi everyone,

I am new to pfsense and firewall issue, so I hope someone here can give me a hand about this issue.

The environment is the following:

Pfsense IP: 192.168.1.1  –> Firewall
Mail Server 1: 192.168.1.2  --> currently hosting my company emails
Mail Server 2: 192.168.1.3 --> just for smtp service

Pfsense NAT: External 25 --> 192.168.1.2 port 25
                      External 1025 --> 192.168.1.3 port 25

Here is the situtation.

Mail Server 1 can send out emails to other domains and receive emails from other domains.
Mail Server 2 can send out emails to other domains as well, however it has problem to send emails to Mail Server 1 and it has the following error msg in mail log

45EB062CB5: to=tsuser1@xxx.com, relay=none, delay=29822, delays=29790/0.01/32/0, dsn=4.4.1, status=deferred (connect to mail.xxx.com[x.x.x.x]:25: Connection timed out)

remarks: xxx.com is my company domain, x.x.x.x is my company public IP(Pfsense External IP)

In this situation, I believe there is a connection problem from Mail Server 2 to external IP port 25, I think there should have some Firewall Rules I need to add to solve this problem.

Thanks./tsuser1@xxx.com

Make sure that you have NAT reflection turned on (though I think I read somewhere on the forums that it is currently broken).

I had the same problem with my mail server, NAT reflection fixed it perfect.
