Primary Interface:
You can select either:
11. Embedded modem (PPP link)
12. PPP over Ethernet (PPPoE)
13. Ethernet Port
Secondary Interface:
You can select either:
14. Embedded modem (PPP link)
15. PPP over Ethernet (PPPoE)
16. Ethernet Port
As you can see, there are
two
options for interfaces, primary and secondary.
If the “Fail over” feature is enabled, when the primary WAN interface is no longer available, the Bytton
LTE equipment automatically switches to the secondary interface.
Fail-over
: When Enabled, the equipment will automatically switch from the primary WAN interface to the
secondary interface, in case the main connection is broken . By default it is disabled.
Ping IP
: an external address that will be periodically pinged. If it does not answer, Rohde & Schwarz
Topex S.A. Bytton will decide whether the primary interface for the Internet is unavailable and it will switch
to the secondary interface.
Ping Interval
: the time period for pinging the respective address, for example ten or 25 seconds in the
above example.
If the interval is too small, even a momentary interruption will cause the unneeded switching from the
primary WAN interface to the alternate one.
But if the period is too long, for some time there will be no Internet connection available (the primary WAN
interface has failed but the secondary one has not yet been put in use).
Masquerade
:
Enable or Disable masquerading.
Click the link located at the bottom, above the “Save” button, to go to the
secondary page with settings for NAT (masquerade).
The NAT table is by default empty or contains just the most used outgoing interfaces, WAN and PPP, so
in the beginning you should use Add New if you need new entries:
