I have a simple cable modem (Thomson TWG870).
I've looked in the manual, but there is no option to select the NAT type the router uses. Can I conclude that the only - and default - mode is port-based?
The computers on the LAN can access the internet by default (without any configuration required to the router). Does this mean the NAT functionality is enabled by default?
Sorry but Your answer doesn't target my questions absolutelly. I know that for WAN initiated connections i have to explicitable setup port-forwarding but i've asked about LAN initiated connectins. If In such a case port-forwarding is enabled by default (without any setup)? – Mulligan – 2016-06-10T14:32:12.193
The fact that you included
NAT
in both of your questions lead me to assume that you knew what it meant. Connections initiated internally will indeed get forwarded back to the initiator automatically. – Julie Pelletier – 2016-06-10T15:55:53.410
