SIP on FTTH systems

Rather than assign residential and business customers their own /30, to conserve space we give those customers a /32 out of a /24. But when one of these static IP customers wants to send email to another, or the employee wants to VPN into work, they can't. MACFF is supposed to solve that (we haven't turned it on, yet, because the vendor's implementation requires us to do some work on our provisioning system to make it easier).

In my not-at-all humble opinion, in an eyeball network, you almost *never*
want to make it easier for houses to talk to one another directly; there
isn't any "real" traffic there. Just attack traffic.
Well, ok; slim chance of P2P, but carriers hate that anyway, right? :-)
