Hello Community,
today i have a more specific requirement.
Maybe there is a tested documentation at ZYXEL, which I don't know yet ;)
 
Requirement
During office hours (9 a.m. to 6 p.m.), a connected UTMS stick to a USG should dial in if the broadband connection fails and take over operation until the broadband is reactivated.(for dedicated vLANs - not for all vLANs).
 
It should not be dial in if the broadband is dieconnected in the 24h cycle. :'(
Is there any documentation/handout availible for this type of configuration ?

thx and best regards
Christian

    Hi @ChristianG,
    It does not support dial in within a specific time frame. We only can set “Nailed-Up” to control the connection is always up or dial on demand.

    Hi @Zyxel_Cooldia
    thanks for the quick response. If it's not possible by a USG. Is it possible to connect a ZYXEL LTE 4506 to WAN2 and configure the described requirement ?

    The SIM Card has no flatrate :) it's only to have a backup for VOIP and dedicated vLANs until broadband is down, or the USG wouldn't reconnecte in the night and require a manualy reset by a manualy powercycle ;)

    thx forward

    Hi @ChristianG,
    ZyXEL LTE 4506 does not have schedule dial in.
    Maybe we can try another method, how about create 2 scripts on USG.
    The 1st script is running to shut down the cellular interface at 6 p.m.
    ~~~~~~~~~~~
    configure terminal
    interface cellular1
    shutdown
    exit
    ~~~~~~~~~~~
    The 2nd is cellular interface no shot down at 9 a.m.
    ~~~~~~~~~~~
    configure terminal
    interface cellular1
    no shutdown
    exit
    ~~~~~~~~~~~
    Please note that “Nailed-Up” must enable on cellular interface.

    Hi @Zyxel_Cooldia
    the script idea looks good ;)
    there is a way to add "dependencies" to zyash scripts, e.g.

    if WAN1 changed from "connected" to "disconnected" raise the "no shutdown" script to activate celluar connectivity if required and not permanent ?

    thx for your service

    Hi @ChristianG,
    It does not support flow control on Shell Script.
    e.g. IF else, for loop, and select case.
    But we can add policy route with wan trunk, wan 1 is active mode, cellular is passive mode, then the traffic most time goes to wan 1, unless the wan 1 connectivity check fail.
