LARTC - May 2007 - Re: DGD patch not detecting dead gateway

I have a doubt. If you use such a script monitoring the link status with
ping and then reconfiguring, why do you need the DGD patch? You need to
do some reconfiguration (change multipath to a single default route)
anyway if you use the script, right?
 
Also, the DGD patch uses src to lookup the routing table entry, but if
you have a dynamic IP for the WAN interface (PPPoE, DHCP etc), this
approach is bound to fail, right?

The patches take care of many other issues also. Please refer to the

I had followed that discussion, but my doubt remains. For MASQUERADE
too, it depends on the ''src'' parameter, which was configured
statically.
But after the interface comes up with a new address, the initial
configuration will be invalid because ''src'' is not correct
anymore, it
seems...Or have I have misunderstood the concept?
