Temporarily opening up all incoming WAN connections to a single host in LAN



  • I am having issues getting to configure one account on outlook as the account autodiscovery fails - I have done some reading, it has to be firewall related from pfSense.

    I want to temporarily disable ALL firewall rules and forward ALL incoming connection requests to a single host in the LAN from WAN.

    What is the quickest way to do this? I can do a single port forward but not exactly sure on the settings to allow all ports and all protocols .. just need to do this for 2-3 minutes, get the account configured and then remove the rule.

    thanks for your help!



  • Would probably be easier just to plug your device into the WAN Port and let it get DHCP and do all the magic you need and then reconnect the other device.

    Is there a reason you can't do that?



  • Autodiscovery? If your really mean the thing that tries to guess your account details based on the email address you input in the outlook client your problem has absolutely nothing to do with pfSense, the feature does not require incoming connections at all.

    the only thing that could come into play with pfsense is how your doing dns and if your doing overrides for specific domains/records that could cause a problem.  But concur with kpa there are no inbound ports required for such a discovery.  Its all based upon having the correct dns settings.



  • Why not look for the domains email server settings. Do a quick search, most services have a client settings page. Do it manually and be done with it.
    In my area the ISP of the modem or your service may block the smtp server anyway if it is going to a different ISP. Its a spam thing they have a problem with. So after initial setup and you can receive but not send your going to have to go into server settings anyway to fix.
    Save yourself the hassle and do it manually, the work pays off.
