I need to setup a machine with the ability to switch between 2 different =
gateways automatically.
The system would need 3 nics ( I assume ).
LAN Interface:=20
ip: 192.168.1.1=20
nm: 255.255.255.0
Cable Interface:=20
ip: 24.x.x.x=20
nm: 255.255.255.0
gw: 24.x.x.254
Frame Interface:
ip: 205.x.x.x
nm: 255.255.255.224
gw: 205.x.x.161
Some sort of script that pings a remote host...cable provider's router =
maybe...
When it loses connect, change default gateway to frame.
When cable comes back up, change default gateway to cable.
Any ideas on this? I have a pretty good idea of what is needed but a =
good how-to is=20
certainly in order. Thanks in advance.
