Same reasoning as in bdedb798150a58ad7ce3c4741f2f31df97e84c3f; don't set
default firewall zone to wan as the firewall zone for the ipip interface
can be configured in the firewall config or it makes it impossible not to
specify a firewall zone for the ipip interface.

The package supports IP in IP by registering the ipip protocol handler
Following options are configurable
-peeraddr (IPv4 remote address)
-ipaddr (IPv4 local address)
-ttl (time to live of encapsulating packet)
-tos (type of service of encapsulating packet either inherit (outer header inherits the value of the inner header) or hex value)
-df (don't fragment flag of encapsulating packet)
-mtu (IPIP tunnel mtu)
-tunlink (bind tunnel to this interface)
-zone (firewall zone to which the IPIP tunnel will be added)
