PFsense home firewall, users can not pull any webpage or ping any outside host.

It's a very long story but last night I tried upgrading my PFsense hardware.. it did not work out because of a nic compatibility issue.  So after reverting back to my original hardware in the wee hours of the morning I discovered that the firewall itself can get outside, but no client can.

I booted it up one of the last times and it was able to check and see that there was an update avail for it.. Curiously I told it to update and it successfully did.

I go to my Win8.1 pc and it cannot surf out anywhere.. it cant even ping any external host by UNC or IP.  I have double checked the DHCP settings and they are correct.  I test my ipad.. nope over wifi it cannot access the internet either.

And this morning.. the PFsense box is still able to get outside itself but no one else can.

I'm not a noob to home or business networking but holy crap this is driving me nuts!  I need a different set of eyes..

    Did you load configuration backup after upgrade?

    I did not but the configuration only really had past statistics, like 3 firewall rules and a traffic shaper (very generic).  I actually figured it out late saturday night... PFsense does not like my on-board realtek nic.  So much so that while physically recognized it refused to pass any traffic.  I tried both interfaces on both cards.. the problem followed the card.

    I figured out the issue was one of my two nics.
