Replication uses one of two transport mechanisms, RPC over IP or SMTP. So
when you list your transports as either IP or RPC those two things actually
mean the same thing. All you replication will be done using RPC over IP.
SMTP transport can only be used between DC's in different domains. That's
just a terminology thing, you don't have a problem here. Use RPC over IP for
everything which is what you are doing anyway.

Your intra-site replication times are a little mean. Twice per hour for
servers in the same site is a little low. Unless you have a very slow LAN I
would look at bringing this down to something like every 5 minutes.

What replication problems are you actually having?
