[tlug] WAN fail-over configuration in Linux-based router

[Jianshi Huang <jianshi.huang@example.com>]

Hi,

Could somebody tell me what's the best way to achieve WAN fail-over
(backup) in a Linux-based router, e.g. openwrt or Vyatta open
networking.

Since full fail-over also needs support from ISP side. Any established
connection can allowed to be dropped if one line drops. New
connections would be routed to the backup line.


Cheers,
Jianshi
