1Host Identification
The SSH client sends a connection request to the SSH server. The server identifies itself with a host key. The
client encrypts a randomly generated session key with the host key and server key and sends the result
back to the server.
The client automatically saves any new server public keys. In subsequent connections, the server public
key is checked against the saved version on the client computer.
2Encryption Method
Once the identification is verified, both the client and server must agree on the type of encryption
method to use.
3Authentication and Data Transmission
After the identification is verified and data encryption activated, a secure tunnel is established between
the client and the server. The client then sends its authentication information (user name and password)
to the server to log in to the server.
6.3.2 SSH Implementation on the NSG
Your NSG supports SSH version 2 using RSA authentication and four encryption methods (AES, 3DES,
Archfour, and Blowfish). The SSH server is implemented on the NSG for management using port 22 (by
default).

Misc setting
Continuously capture
and overwrite old ones
Select this to have the NSG keep capturing traffic and overwriting old packet capture
entries when the available storage space runs out.
Captured Packet Files When saving packet captures only to the NSG’s onboard storage, specify a maximum
limit in megabytes for the total combined size of all the capture files on the NSG.
When saving packet captures to a connected USB storage device, specify a maximum
limit in megabytes for each capture file.
Note: If you have existing capture files and have not selected the
Continuously capture and overwrite old ones option, you may need to
set this size larger or delete existing capture files.
The valid range depends on the available onboard/USB storage size. The NSG stops the
capture and generates the capture file when either the file reaches this size or the time
period specified in the Duration field expires.
Split threshold Specify a maximum size limit in megabytes for individual packet capture files. After a
packet capture file reaches this size, the NSG starts another packet capture file.
Duration Set a time limit in seconds for the capture. The NSG stops the capture and generates the
capture file when either this period of time has passed or the file reaches the size
specified in the File Size field. 0 means there is no time limit.
File Suffix Specify text to add to the end of the file name (before the dot and filename extension)
to help you identify the packet capture files. Modifying the file suffix also avoids making
new capture files that overwrite existing files of the same name.
The file name format is “interface name-file suffix.cap”, for example “vlan2-packet-
capture.cap”.
Number of Bytes to
Capture (Per Packet)
Specify the maximum number of bytes to capture per packet. The NSG automatically
truncates packets that exceed this size. As a result, when you view the packet capture
files in a packet analyzer, the actual size of the packets may be larger than the size of
captured packets.

CHAPTER 8
Troubleshooting
This chapter offers some suggestions to solve problems you might encounter.
None of the LEDs turn on.
Make sure that you have the power cord connected to the NSG and plugged in to an appropriate
power source. Make sure you have the NSG turned on. Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you should contact your
local vendor.
Cannot access the NSG from the LAN.
• Check the cable connection between the NSG and your computer or switch.
• Ping the NSG from a LAN computer. Make sure your computer’s Ethernet card is installed and
functioning properly. Also make sure that its IP address is in the same subnet as the NSG’s.
• In the computer, click Start, (All) Programs, Accessories and then Command Prompt. In the
Command Prompt window, type "ping" followed by the NSG’s LAN IP address (192.168.1.1 is the
default) and then press [ENTER]. The NSG should reply.
• If you’ve forgotten the NSG’s password, use the RESET button. Press the button in for about 5 seconds
(or until the SYS LED starts to blink), then release it. It returns the NSG to the factory defaults (password
is 1234, LAN IP address 192.168.1.1 etc).
• If the NCC has managed the NSG, check the NCC's Site-Wide > Configure > General setting screen
for the NSG's current password and the NCC's Gateway > Configure > Interface addressing screen for
the NSG's current LAN IP address.
• If you’ve forgotten the NSG’s IP address, you can use the commands through the console port to
check it. Connect your computer to the CONSOLE port using a console cable. Your computer should
have a terminal emulation communications program (such as HyperTerminal) set to VT100 terminal
emulation, no parity, 8 data bits, 1 stop bit, no flow control and 115200 bps port speed.
I cannot access the Internet.
• Check the NSG’s connection to the Ethernet jack with Internet access. Make sure the Internet
gateway device (such as a DSL modem) is working properly.
• Make sure that you enter the correct settings in the Configuration > Interface > Ethernet screen. Use
the same case as provided by your ISP.

My packet capture captured less than I wanted or failed.
The packet capture screen’s File Size sets a maximum size limit for the total combined size of all the
capture files on the NSG, including any existing capture files and any new capture files you generate. If
you have existing capture files you may need to set this size larger or delete existing capture files.
The NSG stops the capture and generates the capture file when either the capture files reach the File
Size or the time period specified in the Duration field expires.
My earlier packet capture files are missing.
New capture files overwrite existing files of the same name. Change the File Suffix field’s setting to avoid
this.
I cannot access the NCC portal.
• Check that you are using the correct URL:
• NCC: https://nebula.zyxel.com/
• Make sure your computer’s Ethernet card is installed and functioning properly.
• Check that you have Internet access. In your computer, click Start, (All) Programs, Accessories and
then Command Prompt. In the Command Prompt window, type ‘ping’ followed by a website such as
‘zyxel.com’. If you get a reply try to ping ‘nebula.zyxel.com’.
•If your Nebula Connectivity Status on the Dashboard shows Disconnected (Server unavailable), check
your Internet connection.
•If your Nebula Connectivity Status on the Dashboard shows Disconnected (DNS queries fail), check
your DNS configuration.
• Make sure you are using the correct web browser. Browsers supported are:
• Firefox 21 or later
• Chrome 26.0 or later
• IE 10 or later
• Internet Explorer 9.0 or later
• Safari 6.0 or later
I cannot log into the NCC portal.
• Open your web browser and go to https://portal.myzyxel.com. Sign in with the correct email and
password. Click Not a Member Yet if you don't have a myZyxel.com account and create an account.
• Then go to https://nebula.zyxel.com using a supported web browser.

The NSG can’t be managed by the NCC.
• Make sure you have registered the NSG to a site and an organization in the NCC at https://
nebula.zyxel.com.
Register the NSG by entering its MAC address and serial number. The serial number and MAC address
can be found in the Status screen or the device back label on the NSG.
• Check that you have Internet access. In your computer, click Start, (All) Programs, Accessories and
then Command Prompt. In the Command Prompt window, type ‘ping’ followed by a website such as
‘zyxel.com’. If you get a reply try to ping ‘nebula.zyxel.com’.
8.1 Resetting the NSG
If you cannot access the NSG by any method, try restarting it by turning the power off and then on
again. If you still cannot access the NSG by any method or you forget the administrator password(s), you
can reset the NSG to its factory-default settings. Any configuration files or shell scripts that you saved on
the NSG should still be available afterwards.
Use the following procedure to reset the NSG to its factory-default settings. This overwrites the settings in
the startup-config.conf file with the settings in the system-default.conf file.
Note: This procedure removes the current configuration.
1Make sure the SYS LED is on and not blinking.
2Press the RESET button and hold it until the SYS LED begins to blink. (This usually takes about five seconds.)
3Release the RESET button, and wait for the NSG to restart.
You should be able to access the NSG using the default settings.
