The ZyXEL VMG1312 has a web interface and a Command Line Interface (CLI). The CLI can be reached by telnet or ssh. Usually the CLI is not needed to be used as most of the config changes can be done from the Web interface. However, here are some useful commands for the CLI.
 
==== Show the list of commands: ====
?
 
The 'ip6tables' command is available from the shell prompt, but AAISP's config means getting a shell prompt is a little complicated.
 
==== Show running processes and CPU/memory information: ====
top
or
 
 
==== Change LAN address to be 192.168.100.1: ====
lan config --ipaddr primary 192.168.100.1 255.255.255.0
Note: Check your DHCP settings when changing the LAN address, the DHCP range may well change itself when you change the LAN address this way anyway.
 
=SSH access=
[[Category:ZyXEL_VMG1312]]
The ssh daemon on the ZyXEL is provided by 'dropbear', and (at least on AAISP's standard firmware) is an antique version dating from July 2005 and which only offers one key-exchange algorithm (diffie-hellman-group1-sha1), an algorithm which is no longer considered secure and might not be used automatically by clients.
 
The workaround is to manually specify their only available algorithm. E.g. for an openssh client:
ssh -o KexAlgorithms=diffie-hellman-group1-sha1 admin@192.168.1.1
