Cannot send email - Outlook behind pfsense



  • Hi all,

    We recently replace our very slow adsl modem/router for a faster internet by satelite connection.

    The satelite people (skydsl) only supply a modem. So we are using pfsense as a default gateway and router but a windows 2008 DHCP/DNS server
    We have LAN interface set as gateway . Attach to that lan port, we have a HP switch which redistribute the internet to our 10 office computers.

    On the LAN:

    • all desktop has internet access and correct ip/gateway info
    • Using windows remote desktop connection on the lan, we can access all computers and we can do maintenance
    • I can ping DHCP/DNS server
    • I can receive email on outlook

    The problem is that we are unable to send email from the office.
    If I plug the original router back, then the email problem goes away..
    We tried the suggestion from this link but didn't solve our problem

    We are on pfSense 2.3.4-RELEASE
