    Thanks for the input, I tried it, even tried leaving the destination port blank so that all traffic outbound from that server would be directed out via it's public address. Still doesn't work, as a matter of fact, no internet connections work at all not even inbound. But when I change outbound back to automatic, internet connections work again but I am back to square one with all outbound traffic going out via the wan interface ip and not the server specific public ip's (virtual ip's) I assigned and active sync of course doesn't work then. I am not using 1:1 nat, just some virtual ip's on the wan interface for my public ip addresses and some port forwarding. Very simple configuration that has me stumped lol

    If I have overlooked something please feel free to correct me, my ego is not a concern at this point in time LMAO

    Thanks again,

    @cmb:

    …as NAT reflection in general sucks ...

    Maybe a dumb question: What would you prefer to use in such a scenario?

    It won't work, if you do not disable captive portal on OPT1.

    If you do, so does NAT.

    Well, I made progress, but I believe that I do need ICMP to be routable from both the Internal and External interfaces to the DMZ server.  I simply don't see a way to do this with port forwarding, while 1:1 NAT creates issues with SIP and the source address of the DMZ server when communicating with Internal network devices.  I'm just going to use a different router until I can figure this out.  It's a shame that testing on this particular deployment requires as much preparation and down time as it does.  It may be that I can do this by editing IPtables directly, but i'm not sure when I will be able to spend more time testing.

    Thank you for the advice.

    I seem to remember that there were PPPoE problems in an early 1.2 version.
    Update to 1.2-release or one of the 1.2.1RCs and see if your problem goes away is my best bet.

    You are going to have to give a bit more detail on this if you want someone to help. Do all port-forwards from all secondary WANs initally work, but stop working? What do you see in the logs when the port-forwards stop working? What do the state tables look like? What you are saying doesn't make any sense logically.
    BTW- you should not use registered ports for external port shifts. (tcp/udp 2000 is Cisco SCCP.)

    Ok. Problem solved (in part at least).

    I've disabled NAT reflection, created some DNS forwarder and Port forward entries and it works as expected. Well, the only drawback is not being able to ping server from LAN, but it should be enough.

    BTW. I've encountered strange thing (bug) in Firewall Aliases. As all of us I'm lazy so I tried to create alias for all ports my server should provide and then create just one Port Forward entry using alias created earlier. But it didn't work, I couldn't connect to server. So I've removed alias and created 5 separated entries in Port Forward (one for each port) and it works! Is this a bug or just my misunderstanding what is a purpose of port aliases?

    BTW2. I've encoutered another problem with strange HTTPS lags which I describing here: http://forum.pfsense.org/index.php/topic,12343.0.html

    Best Regards,

    NAT and firewall are separate rulesets.
    So yes if you delete the "allow all" rule you block everything.

    Although i dont think 1:1 NAT is easier.

    1:1 NAT approach:
    1: set the 1:1 mapping.
    2: create an alias containing all the needed ports.
    3: create a firewallrule allowing the alias for the server in question

    normal port-forward approach:
    1: create an alias containing all the needed ports.
    2: forward the alias to your server ports. The corresponding firewallrule gets autocreated.
    3: enable AoN and set the outbound mapping.

    You just the do "about" the same thing at different places.
    IMO the second is "better" because it works with NAT-reflection (see link above).
    Also you dont forward everything per default leaving the option to use a single IP for multiple Server.

    @GruensFroeschli:

    If you can access it via a browser, the portforward itself is working.
    –> Not a problem on the pfSense side.

    Doublecheck if your client is correctly configured.

    I did that yesterday (rebuilt the client) and it didn't make a difference.

    I tried AGAIN today, and guess what, it started working again. I am not sure if a patch was applied to the client overnight to fix something.

    The fact that the repository was accessible by the browser and not via a client made me think that the client used a different set of HTTP methods to get to the repository.

    In any event, thank you everyone for your help, I appreciate everyone's input.

    You cannot have a /32 as WAN (unless you have PPPoE WAN).
    And from what you desribe it seems that you just can use the 24.x.111.143/29 block.

    You could go with the "transparent bridge" approach where the pfSense has no IP out of this range.
    In fact the IP you have on the pfSense is only to manage it.
    The clients have then public IP's out of your usable range.
    They have the gateway you have now on the pfSense directly.
    –> The will not send traffic to the pfSense and pfSense will not NAT it.

    Make sure you set the correct gateway and the correct subnetmask
    (are you sure you mean 255.255.248.0? this is a /21 subnet instead of a /29 --> 255.255.255.248)

    Search the forum and the tutorials on how to set this up.

    It won't delete any rules already there but if AoN is enabled no rules will be automatically generated for new LAN type interfaces, just like it states.

    Take care!
    What routers like the afore mentioned do with one of the hosts on a switch port is far from being a DMZ!
    This is called an "Exposed host". Only SOHO marketing calls it a DMZ…

    Once you have a host exposed to the untrusted network (internet) completely, this machine can be compromised. Since it resides within the other machine's subnet it can easily spread malware or access other resources on your LAN. Make sure this host is really safe and locked down…

    An option you could choose is to get a VLAN capable switch and define virtual subnets. This way you can setup a real DMZ and filter or block traffic between your subnets.

    Wikipedia has an article about it:
    http://en.wikipedia.org/wiki/Demilitarized_zone_(computing)

    but the german article describes the "exposed host" way better (it isn't mentioned in the english version at all...).

    Thank you for the layout, in the mean time:

    Figured it out, evidently VMware infrastructure WON'T work on a NAT'd port forward!  So in order to make it work I either have to build a VPN, or give up an external IP (yuck!), unless someone has a bright idea.
