YAMAHA Router filter entries
How it works
Imports only shared firewall-rule JSON and renders the documented YAMAHA Router ip filter / ipv6 filter entry subset using Rev.14-era syntax. Entries are allocated deterministically from number 100. The subset is an unattached ingress convention only: it rejects interfaces, chains other than input, connection state, log prefixes, and comments because those meanings are not preserved. Logging is rendered with the documented pass-log, pass-nolog, reject-log, or reject-nolog action. The model's drop (a silent discard) becomes reject-log or reject-nolog. YAMAHA documents these only as discarding the packet and does not say whether anything is sent back. In a device test on vRX Rev.20.01.03 they sent no ICMP message or TCP RST, for IPv4 and IPv6; other models and revisions are unverified, so check the target router if silence matters. Confirm command support and filter-number availability on the target firmware; nothing is applied.
