Router - TG582N - 3G: Difference between revisions

=== Enabling 3G fallback ===

The most common usage of 3G with the [[TG582N|TG582n]] will probably be to use 3G as a fallback link in the event of the ADSL link going down. There are several ways of achieving this, depending on the degree of automation required and the network/tariff used for 3G. The following notes are intended to provide guidance, but are unlikely to result in resiliance on a par with the Office::1 product.

To configure the 3G link to be permanently up, but traffic only routed when the ADSL link is down, follow the instructions above but then do:

{Administrator}=>ppp rtdelete intf=mobilebroadband

{Administrator}=>ppp rtadd intf=mobilebroadband dst=0.0.0.0 metric=20

{Administrator}=>ppp ifconfig intf=mobilebroadband dnsmetric=20

(This assumes that the routing metric and dns metric for the ADSL link are both set to 10. Larger numbers represent a higher "cost", so interfaces with lower costs will be preferred).
