Port-blocking via the firewall can do that but, depending on the service, you may end up playing whack-a-mole. Depending on how tight a network you want to run, you could block everything outgoing except approved ports, and even that's not perfect.
pfBlocker -> dead. 2.1.4 -> dead. Good luck.
Thanks for the prod, now running 2.2.1 and pfblockerNG. The upgrade went quite well, my IPTV multicast over the iGMP proxy is still working which is what I was scared of.
To set up the UML295 you should do the following:
On your Windows 7 PC follow these instructions to enable IP passthrough: http://pcdn2-download.vzw.com/win/UML295/UML295_IPPT_UserGuide-v2.pdf
1. Plug the UML295 into the pfsense box
2. Go to the Interfaces drop down and click (assign)
3. Select the ue0 Interface from the Available network ports dropdown and press the add button
4. Enable the interface'
5. Select DHCP for the IPv4 dropdown and save
6. Apply the configuration
At this point the interface should work.
You may want to ensure that it still works after a reboot, as I've found that it will not.

Let me know how it goes for you.
What version of OS X Server?
What is your end goal? Not what certificates you think you want where, but what do you want to be able to do with them?
Certificate handling in OS X Server has always been, shall I say, squirrelley.

you'll soon notice that it's a pain and not "easy' :))
Jumbo frames are totally pointless on any remotely modern network. Building TCP/IP headers for lots of packets hasn't been a CPU bottleneck issue for ages and routers can do much more PPS now than they could 10 years ago. Same for switching hardware.
Either it has some CPU/cache/memory hardware problem that is causing page table references or some critical bit of the kernel got corrupted on the CF card - "page fault while in kernel mode" should never "just start happening".
The easiest thing to do is to take out the CF card and re-write it a new good pfSense nanoBSD image. If that works then you are in luck. If the CF card gives errors when writing it, then you know to get another CF card.
If you still get "page fault while in kernel mode" on a clean pfSense boot, then there has to be some hardware problem on the board. Since the CPU, memory is all fixed to the Alix board there is not much benefit in knowing if it is CPU or memory or…
I am using 2 to test currently, although will be using 3 when I go live.
At the moment I have set the non-active one to not be in the "allconnections" gateway group so only the 2 active ones are in there.
