But where?

In the home environment, the CPE is the logical place to exercise central
control over all access from the Internet to the home
e.g. IPv4 port-forwarding, and IPv6 permit to particular hosts.

But, in the cellular or WiFi hotspot environment, there isn't a nearby
firewall that you control.
And on WiFi, there isn't a place for a firewall between you and other
people sharing the same hotspot!

My ISP, Internode does have a basic ACL firewall service available for
ADSL, cellular etc
It can be on, or off per subscriber.  When on, it provides
*Increased protection against spreading network worms, viruses and email
- Outgoing email must be sent via mail.internode.on.net or
- Blocks vulnerable Windows network ports (135, 137, 138, 139, 445) inbound
and outbound.

*Increased protection against intrusion attempts to your broadband router
or server:*
- Blocks web, telnet, ssh and proxy ports (80, 443, 22, 23, 8080, 3128)
inbound (to you) only.
This isn't a "stateful firewall" that blocks all incoming connections.
However, I think this inbound and outbound ACL filter is quite a useful

In my opinion, mobile devices (cellular and WiFi) need to implement and be
responsible for their own security.
