IPsec wifi link in ad-hoc mode

Hello.

I set up my two laptops to communicate in wifi ad-hoc mode.???

One of the laptops (192.168.1.3) acts as a router and a DNS server for the
other (192.168.1.4).

As I don't want anybody to use my router as a gateway, I must secure it.

I enabled a WEP encryption key between the two of them, but it's hardly
extremely secure.

So I set up an IPsec link between them; it works ok, but I don't know if
it's enough to guarantee that nobody can hijack my connection, using my
gateway to spam/spoof/etc.

How can I make sure that only 192.168.1.4 connects to 192.168.1.3? Must
I/can I do IP filtering? MAC addresses filtering?

If yes, how do I do that?

Thanks!
