=== 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:

Line 31:

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

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

and, to bring the 3G link up when the router is power-cycled:

{Administrator}=>:ppp ifattach intf=mobilebroadband

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. These can be checked with:
