The product does contain open source software under the GPL. We have some of the software on the VMG1312: Software page. A copy of the software should be available by contacting ZyXEL:

MTU 1508

An independent developer, unconnected with AA, has produced a custom build based on the open-source sourcecode from ZyXEL which offers MTU 1500+8=1508 so full IP 1500 byte packets can be sent and received. Support for multiple telnet instances is also another benefit. AA is not associated with this development, cannot guarantee its quality nor be responsible for any problems or damage resulting from its use. AA does not recommend the use of this code and has not reviewed it. You must understand that use is at your own risk. Source code can be inspected and you should do so and build it yourself. As this is a third-party development, do not ask tech support about this. Discussion and details can be found on the web site.
