Change The Mtu Size - NETGEAR Nighthawk X6 AC3000 R7850 User Manual

Note: The default setting of the Connection Mode menu is Always On to provide
a steady IPv6 connection. The router never terminates the connection. If the
connection is terminated, for example, when the modem is turned off, the router
attempts to reestablish the connection immediately after the PPPoE connection
becomes available again.
9. Select an IP Address Assignment radio button:
• Use DHCP Server. This method passes more information to LAN devices but
some IPv6 systems might not support the DHCv6 client function.
• Auto Config. This is the default setting.
This setting specifies how the router assigns IPv6 addresses to the devices on your
home network (the LAN).
10. (Optional) Select the Use This Interface ID check box and specify the interface ID
to be used for the IPv6 address of the router's LAN interface.
If you do not specify an ID here, the router generates one automatically from its MAC
address.
11. Select an IPv6 Filtering radio button:
• Secured. In secured mode, which is the default mode, the router inspects both
TCP and UDP packets.
• Open. In open mode, the router inspects UDP packets only.
12. Click the Apply button.
Your settings are saved.
