Firewall blocking mail server webmail



  • Hello

    I have a mail server behind a pfSense firewall. I have port 8100 open to allow access to the SSL cert protected  application. I have pointed the domain name to the mail server in DNS. I should get the WebMail page when I put in, as an example, https://acme.com:8100. Here are my NAT and Rule entries:

    NAT WAN
    WAN TCP      *            *              xxx.xxx.49.33  8100      192.168.31.35  8100

    Rule
    IPv4 TCP      *            *              192.168.31.35  8100          *          none

    Is there something else I need to do, so that the name will resolve to the correct location? When I put in the https:://acme.com:8100, I get "Site cannot be reached ERR_CONNECTION_TIMED_OUT.

    I can connect if I do the https://xxx.xxx.49.33:8100, but it gives me the certificate not safe screen, since the certificate is for acme.com. I have a person on the server who needs things kept simple.



  • Based on your explanation, there is a problem with the DNS configuration.
    Make sure that you can resolve the name into the expected IP address first.



  • Thanks. Did a nslookup from where I was working and realized the DNS return was incorrect. It had not updated since the change. Went to a station outside my network, and the IP was correct.

    Thanks again.
