Can't receive emails - Can send emails

@DanishDynamite:

Hey there!

Can someone tell us if we are doing anything wrong?

Example:

TDCNET TCP * * TDCNET address 25 (SMTP) 192.168.1.254 25 (SMTP) SMTP til Exchange Server

Whats your wan firewall rule look like?

I am not sure what rule you mean, so therefor, i am gonna give you all our rules ;)

TCP * * TDCNET address 25 (SMTP) * none   SMTP Test

TCP * * 172.16.1.11 80 (HTTP) * none

TCP * * TDCNET address 110 (POP3) * none

TCP * * TDCNET address 143 (IMAP) * none

~~So you have a port forwarding rule.

TCP * * 192.168.11.2 25 (SMTP) * none

I can't tell for sure whether you have a matching NAT rule?

WAN TCP * * WAN address 25 (SMTP) 192.168.11.2 25 (SMTP)~~

Best to set up the NAT and let it generate the matching Firewall rule (bottom of NAT GUI page)

EDIT:  Sorry, misread your original post.  Last line above still applies though.

Okay . Didn't realise that! Going to change our rules, so they will be generated from the NAT, since it's easier :)
However, i doubt it will fix our problem.

Your rule should look like-

TDCNET  TCP  *  *  192.168.1.254  25 (SMTP)

not

TCP    *    *    TDCNET address    25 (SMTP)

You never mentioned your Port Forwardings before. Did you set those up?
Without an Inbound Port Forward your firewall rule never gets any traffic from WAN.

Yeah, we did set this up. The only difference was, that i created the rules first, and then configured the NAT. I didn't realise you could configure NAT, and then it would create the rule automaticly.

So now, my NAT looks like this:

TDCNET TCP * * TDCNET address 25 (SMTP) 192.168.1.254 25 (SMTP) Test SMTP NAT

And therefor it have created a rule that looks like this:

TCP * * 192.168.1.254 25 (SMTP) * none   NAT Test SMTP NAT

Does it work now?

[DanishDynamite]

It seems that way. We still can't receive emails, but we can see that we get trough the firewall now, and that didn't happen before. So the remaning problem is probably at the Exchange Server.

Thank you so much for your help :)

Just had this issue. Found a post back in 2011 that said to try adding a "To" and "From" rule in the Captive Portal Menu under Allowed IP Adresses Tab.

I did it, and now I can receive email.
Why is it that my server's IP needs to be input here.
Of course, in PFSense 2.03 you can't place a "To" and "From" rule, you have to select a "Both" rule.
But this is very wierd to me. I did not select a captive portal interface during setup.
When I do elect to install a captive portal interface, will I have to create different selections for the captive portal, and how will that affect my email server routing.
