Pretty much every consumer router has an inbuilt stateful firewall. That's why you need port-forwarding on your router if you want inbound connections to NAT'd devices on your LAN. Pretty much every commercial/business grade router (and even Layer 3 switches) can also act as firewalls, although in the corporate world it' s usual to have a separate firewall appliance at or near the edge of the network (and often also between network segments within a larger network). I personally run a Cisco business-grade router and it has quite reasonable firewalling capabilities, but even the ISP-supplied routers I've had in the past have firewalling enabled by default and need to have port-forwarding setup to allow inbound connections for e.g. ssh, vpn or other services I may want to expose. (These days I use a zero-trust vpn solution that doesn't require inbound port-forwarding, but that's another discussion altogether). -- ========================================================================================================== Rodney Baker rodney.ba...@outlook.com.au ========================================================================================================== _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
