NAT implementations get broken all the time (NAT slipstreaming attacks). If a manufacturer is incompetent enough not to have a firewall on by default, they are probably also shipping a vulnerable NAT.
NAT slipstreaming depends on confusing fragmentation assemblers and application aware parsers. Those exist in firewalls as well. It’s not NAT specific.
