[pfSense Support] IPSec Behind NAT Device

[tung.tman]

Dear all,

First I'm using pfSense 1.2.1-RC2
I've managed successfully IPSec VPN Site-to-site between  pfSense1 [PPPoE] <===>  [PPPoE] pfSense2. (Both Static PPPoE IP Address)
But when I need to create Site-to-Site tunnel between my pfSense1[PPPoE] <===> [PPPoE] Modem <-> pfSense2, It cannot create a tunnel. As I see, It failed may be it because of I can't define the Remote Identifier in the Phrase 1 (Default as the Remote Gateway-IP of Modem, but in this case it is the IP WAN of pfSense2). But in pfSense 2.0 Alpha I see this option.

So I want to ask you whether I can set this parameter in config.xml file? And with which tag?

Thank you so much.

Hello,

I've checked the release notes and I think that IPSec NAT-Traversal (feature you need here) is only supported in version 2.0.

Hope this helps.
