UMTS Fallback during business hours
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 flatrateit'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.
