Remote Auth Suggestions ~~~~~~~~~~~~~~~~~~~~~~~ Found these very interesting security methods/topics.
< authpf > Allows a secure remote auth, kind of reverse "Captive Portal" only from WAN. (short explanation taken from FreeBSD Manual Pages) "authpf is a user shell for authenticating gateways. It is used to change pf(4) rules when a user authenticates and starts a session with sshd(8) and to undo these changes when the user's session exits. Typical use would be for a gateway that authenticates users before allowing them Internet use, or a gateway that allows different users into different places."
< Port Knocking > Port Knocking allows a firewall to protect private IP 'LAN services' by keeping all ports closed until a specific sequence of network traffic is sent.
Being a FreeBSD based firewall, is there any chance of seeing these implemented in SmallWall any time soon ?
Well, the first one is out because we do not use pf for the firewall. That was actually the basis for the original split from m0n0wall to pfSense, and the plugin architecture came later.
Port knocking might be able to be done, however, but it would NOT be a small project. If you are interested in looking into this, I can help you with development. But right now I am way behind on my own projects!
