No, actually it doesn't matter _where_ the client is.  DynDNS records
the "public" point where the client is talking to the network, not its
internal address.  Whereever RR gives you your IP address ( whether the
modem, the router, the firewall ) is the point that DynDNS is concerned
with, not the internal configuration of your network.
