Use this screen to configure through which interface(s) and from which IP address(es) users 
can use various protocols to manage the ZyXEL Device. See 

 for 

background information. To open this menu, enter 11 in menu 24.

Start Date

Configure the day and time when Daylight Saving Time starts if you selected 

Enable Daylight Saving. The o'clock field uses the 24 hour format. Here are 

a couple of examples:
Daylight Saving Time starts in most parts of the United States on the first 

Sunday of April. Each time zone in the United States starts using Daylight 

Saving Time at 2 A.M. local time. So in the United States you would select 

April, 1st, Sun., 2.
Daylight Saving Time starts in the European Union on the last Sunday of 

March. All of the time zones in the European Union start using Daylight Saving 

Time at the same moment (1 A.M. GMT or UTC). So in the European Union 

you would select March, Last, Sunday. The time you type in the last field 

depends on your time zone. In Germany for instance, you would type 2 

because Germany's time zone is one hour ahead of GMT or UTC (GMT+1). 

End Date

Configure the day and time when Daylight Saving Time ends if you selected 

Enable Daylight Saving. The o'clock field uses the 24 hour format. Here are 

a couple of examples:
Daylight Saving Time ends in the United States on the last Sunday of October. 

Each time zone in the United States stops using Daylight Saving Time at 2 A.M. 

local time. So in the United States you would select October, Last, Sunday, 2.
Daylight Saving Time ends in the European Union on the last Sunday of 

October. All of the time zones in the European Union stop using Daylight 

Saving Time at the same moment (1 A.M. GMT or UTC). So in the European 

Union you would select October, Last, Sunday. The time you type in the last 

field depends on your time zone. In Germany for instance, you would type 2 

because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
