As mentioned by the people above, the key to your problem is port mapping. This needs to be set up on your router, or you can download something like "Huashengke" to solve it.
As for the router settings, if your router uses the viking's fw, you can refer to some content in . But you said you just bought a new router, and I think it probably doesn't use the viking's fw.
Appendix:
Some Telnet commands: (mainly for Vinking series chips)
MAC address list clearing:
Run CMD, enter arp -d and press Enter
Backing up FW:
tftp -i 192.168.1.1 get TEimage.bin
Upgrading FW:
tftp -i 192.168.1.1 put TEimage.bin
Setting method of TELNET console:
Login port setting
modify nbsize httpport <decvalue>
modify nbsize telnetport <decvalue>
modify nbsize ftpport <decvalue
Turning off SNMP
modify snmp trap disable
If it is not completely turned off, and the SNMP vulnerability can still be found with a scanner, it is best to add the following two sentences:
$delete snmp comm community private
$delete snmp comm community public
Modifying the MTU value in the telnet console:
modify ppp intf ifname ppp-0 mtu 1480
ifconfig eth0 mtu 14xx (Linux Shell)
Setting VPI and VCI values (provided by the ADSL operator, assuming: VPI is 0, VCI is 33)
add interface atmpvc
set interface atmpvc0 vpi 0
set interface atmpvc0 vci 33
Specifying the line mode (assuming 2: G.dmt)
set interface adsl standard 2
Setting the encapsulation type (5 is PPPOE)
set interface atmpvc0 encap 5
Setting the username and password during dial-up (provided by the ADSL operator, assuming: username is adsl, password is adsl)
set interface atmpvc0 user adsl
set interface atmpvc0 password adsl
Enabling NAT (Network Address Translation)
set interface atmpvc0 nat on
Turning off bridge mode
set interface atmpvc0 bridge off
set bridge off
Saving settings
save
Rebooting
reboot
After the startup is complete, when the modem is synchronized, you can surf the Internet normally.
Entering the WAN IP address and subnet mask (provided by the ADSL operator, assuming the IP address is 202.106.69.75 and the subnet mask is 255.255.255.0)
set interface atmpvc0 ip 202.106.69.75 255.255.255.0
Entering the NAT IP address and subnet mask (the same as above)
set interface atmpvc0 natip 202.106.69.75 255.255.255.0
Entering the NAT gateway IP address (provided by the ADSL operator, assuming the IP address is 202.106.69.71 )
add route 0.0.0.0 0.0.0.0 202.106.69.71 atmpvc0
Turning off bridge mode
set interface atmpvc0 bridge off
set bridge off
Opening the bridge command line setting method: (without resetting the modem)
delete ppp intf ifname ppp-0
create eoa intf ifname eoa-0 lowif aal5-0
create bridge port intf ifname eoa-0
modify bridge mode enable wan2wan enable
commit
Then you can immediately try dialing with the PC
After the PC dialing is successful, you can turn off unnecessary things like IP filtering and NAT on the modem (it's okay if you don't turn them off), and then connect to the wireless router for settings.
Setting IP session
modify nbsize maxipsess XXX
Note: XXX is the value you want to modify
Method to adjust the time in ADSL
1. Log in to ADSL with telnet:
2. Type the following commands:
modify sntp cfg disable
modify system timezone "CCT"
create sntp servaddr dname time.nist.gov
modify sntp cfg enable
commit
reboot
Enabling the UPnP function:
After logging in to the device with telnet, enter
modify upnp cfg nbstatus enable
commit
reboot
The device will restart!
To check whether the device's upnp is enabled, you can do this
After logging in with telnet, enter
$get upnp cfg
Get
Next Boot Status : enable
Advertisement Cache Age(sec) : 1830
Removing the setting of the USB interface
Log in with telnet and execute the command
$delete usb intf ifname usb-0
$commit
即可。
Current Status : enable
Saving settings
Save/ commit
Rebooting
Reboot
Postscript: Even if your router does not use the viking's fw, some of the commands may be similar, and you can still refer to them. As for more commands, you can back up the fw to the local computer and open it with a hex editor to view directly.
