Possible to setup pfsense with 1 NIC? Serving IPsec VPNs to remote users
-
Hello,
Iam interested in configuring pfsense on a box only with 1 NIC and 1 Public IP. The reason is that I want this server to recieve VPN connections through ipsec from users through the internet.
So in other words incoming and outgoing connections can all happen on 1 NIC because of this nature.
Question:
a.) Is this possible?
b.) When setting up the vpn it asks for a range of IPs to use for the clients. How can i solve this if I want my users to share the public IP. How do I "create" the rest of ips it will give the clients?Thanks

It should be possible to do that. I have heard of others doing similar setups, just configure WAN to be in your local network, and set LAN on an unused subnet and let it sit unplugged.
On 2.0 you can disable LAN and run in a single-nic mode, aka "appliance" mode.

Hello,
One quick question. Is the implementation of ipsec based on l2tp for this manner? Thanks again.

in 1.2.3, IPsec is just IPsec, no l2tp. In 2.0 it should be possible to use l2tp+ipsec.
