[pfSense Support] Reduce WAN NIC to 10Mbps?

2007-06-14 Thread Tortise
Hi

My ISP researching a problem with packet loss advises me to: Set your firewall 
for 10mbps full-duplex, auto negotiation off, and 
then run your tests again.  This is presumably to match their 10M Wireless 
Gateway.

Can we do this somehow?  I am running dc class NIC's.

Kind regards
David Hingston

Have a look at http://doc.m0n0.ch/handbook-single/#FAQ.hiddenopts .
These options apply to pfSense as well. You can hardcode the speed and
duplex by adding the appropriate flag to your downloaded config.xml and
reupload it again.

# interfaces/(if)/media and interfaces/(if)/mediaopt

If you need to force your NIC to a specific media type (e.g. 10Base-T
half duplex), you can use these two options. Refer to the appropriate
FreeBSD manpage for the driver you're using to see which options are
available (or run ifconfig -m).

Re: [pfSense Support] VPN NAT for hiding local addresses

Hello,

I am trying to track down some info on how to hide my private IP's when 
connecting to a remote VPN using pfSense. Can anyone help with 
configuration or give me some links to something that may help? 
Apparently the VPN I am connecting to won't allow private IP's as they 
have thousands of tunnels and conflicts always happen.


Thanks

Tim.



Tim,

I'm not exactly sure how you can accomplish this with pf. If I 
understand your problem correctly, you need to NAT the source address of 
traffic that originates from your private network before it gets 
processed by IPSEC. But 'many to one' NAT is performed as packets pass 
out an interface in pf. This would be fine if IPSEC processing happened 
after pf NAT processing but I think the opposite is true :(


If you own a block of public addresses, you could easily perform 1 to 1 
nat ( binat ) which can be applied to private network traffic as they 
pass in your private network interface. This allows the translation to 
happen before the packets are processed by IPSEC on the outbound path of 
your public network interface.


Hope this helps,

-Matthew
