Re: [pfSense-discussion] Dynamic DNS
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. --Bill On 10/16/06, Stefan Tunsch <[EMAIL PROTECTED]> wrote: I'm talking about the integrated dyndns client.

RE: [pfSense-discussion] Dynamic DNS
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?
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.

Re: [pfSense-discussion] Policy Enforcement: Can pfSense beat it?
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? sai On 10/16/06, DarkFoon <[EMAIL PROTECTED]> wrote: Hi everybody.
