[Gllug] IPSec and firewalls

[Jonathan Dye]

This is all theory for now but I'm looking into all this stuff. 

I want to set up a wireless network at home.  My home network is currently
like this:

INTERNET <--> 10.12.34.1 <--> 10.12.34.*

and I want to have a wireless network in 10.12.35.* with IPSec between the
wireless machines and the gateway.

SO

INTERNET <--> 10.12.34.1 <--> 10.12.34.*
              10.12.35.1
                   ^
                   |
                   \--> 10.12.35.*

So, IPSec between 10.12.35.1 and 10.12.35.* but I don't want the wireless
machines to access 10.12.35.1 without going through IPSec.  Is it possible
to firewall this access off on the router or is that going to stop IPSec?
If I just firewall off tcp and udp will IPSec still get though?
