And this generally applies to services that operators have decided to
run behind a dedicated APN, such as WAP, MMS, Push over Cellular (PoC)
and others. For example, Elisa in Finland seems to be running their
MMSC behind an "mms" APN, with public IP address space, but firewalled
from the rest of the Internet. oFono should isolate such an access
from the rest of the system, since only the MMS client would know how
to work with it properly.
