Ppoe dial-up Environment
When the brush is complete, the WAN will have two
"Wan" and "Wan6"
Where WAN6 uses the DHCPv6 protocol, which can cause conflicts, so I changed it to configure the protocol and save it.
Here you can directly achieve the effect of multiple dialing. But my line is forbidden to dial more.
Intranet environment
Also because the WAN has two reasons, the system log keeps reporting the following error
Fri 10:21:36 2016 Daemon.warn miniupnpd[2702]: SSDP packet-sender 192.168.1.253:49154 not from a LAN, ignoring
Fri 10:21:36 2016 Daemon.warn miniupnpd[2702]: SSDP packet-sender 192.168.1.253:49154 not from a LAN, ignoring
Fri 10:21:36 2016 Daemon.warn miniupnpd[2702]: SSDP packet-sender 192.168.1.253:49154 not from a LAN, ignoring
Google later found the reason for the repeated setting of Nat or UPnP.
So suspect to this wan6 port, after disabling it, no longer an error.
The reason is I shut down the firewall.
The correct mapping method is to add rules to the firewall to develop the corresponding port
Print server Settings
1, external network access to the intranet settings
Firewalls are going to release all WAN traffic.
Port forwarding is also set
2. Printer Setup
Install the driver first on the computer
You can add a printer.
