Re: [pfSense-discussion] Dynamic DNS

2006-10-16 Thread Bill Marquette

Some dyndns providers require us to supply an IP, some don't.  I think
DynDNS isn't one of those, but it does allow us to enter an IP, which
we do - the only one we know.  FWIW, traffic sourced from pfSense will
always (for now) go out your primary WAN interface (the one with the
default route), regardless of what policy routing says.

How can I report an IP other than the WAN IP? I understand that in many

a router between pfSense and the Internet. In this scenario, reporting the
WAN interface IP makes absolutely no sense. I should be reporting the
router's public IP.

Of course, a solution might be to install the client software provided by
DynDNS on some other machine and route this traffic via an appropriate
firewall rule through my WAN interface. But doing it with pfSense would be
much cleaner.

The dyndns client only works at WAN interface and is always reporting the
WAN interface IP. We have code in the next version do dyndns per interface.

Are you talking about  the integrated dyndns client or a client that is
running inside your LAN on a workstation or server?

Hi there!

I recently set up my first pfSense firewall into production.

I am using the load balancing feature. One of the two ADSL connections I'm
using has a dynamic IP address. The loadbalancing itself is working fine,
but I'm having trouble with the Dynamic DNS client set up.

I have created an account with DynDNS and set up pfSense accordingly.

The problem is that pfSense reports the IP address of the WAN interface
instead of providing the public IP of my router.

The second issue is that I don't want to "balance" this url from one
interface to the other. I want to use just one of the WAN interfaces I've
set up. Curiously, pfSense always checks the same interface, which is the
one where I have dhcp set up between WAN and the router.


Any comments on this would be appreciated.

regards.

2006-10-16 Thread Holger Bauer
It only supports reporting it's interface IP (which is in your setup already a 
natted IP behind another device). Either connect the pfSense directly to WAN or 
use dyndns at the host in front of you that is connected to the real wan or use 
a dyndns update client on LAN that frequently checks for the changed IP and 
send it's request out the appropriate wan by utilizing policybased routing.

Re: [pfSense-discussion] Policy Enforcement: Can pfSense beat it?

2006-10-16 Thread David W . Hess
I did a quick search on Cisco policy enforcement and apparently they have user
agents available for Windows and Linux systems.  You say Linux is exempt which
could be for any number of reasons and if so, I would expect BSD to also be
exempt but I would never count on consistency in policy from a college
information services department.

The more recent of these systems have been designed to deal with firewalls and
NAT with various degrees of success (hence the switch to user agents instead of
network scans) but whether your friend could use a BSD firewall to protect his
Windows system from detection depends on the details of what the college is
implementing.

I would think twice before attempting to disguise my Windows machine without
more information.  The use of external firewall devices is common enough however
that trying it as a matter of course should be safe and unremarkable.  pfsense
or m0n0wall should at the minimum just look like any other external NAT/firewall
device.

The policy-enforcement probably only works with either some kind of 
agent allready installed on the PC or via Windows Group Policies forcing 
the installation of such an agent.

It's impossible to to fool such a system, IMO.

Maybe also some kind of captive portal that checks for the existence of 
the above.

Then, with a bridged pfSense, you might be able do it.

 
I ask because you are the experts. I no longer have the free time I 
once had to research this myself (being a student also), so I am 
asking for the knowledge that comes with experience in the field.
 


Trying to circumvent the policy is not a good idea. He should be 
positively sure that he can get away with it (e.g. because he "can't" be 
fired).

Re: [pfSense-discussion] Policy Enforcement: Can pfSense beat it?

2006-10-16 Thread sai

nothing is immune to fingerprinting, but the Cisco device is probably
just looking for Windows boxes. If it isn't a Windows box then it
should ignore it. It might even recognise a BSD box and skip it.  If
ll else fails he can just claim that it is Linux.

What is the Cisco device that is doing the checking?
