[Ddclient-support] DDClient Detecting a Second Gateway (Provider)???

[Larry H. <la...@gr...>]

DDclient Support:

Currently evaluating a "New" Provider, but had left both Gateways left 
connected to our LAN's Switch.  I had assumed that I could just modify 
Static Gateways on all Computers to switch between "Providers", but to my 
surprise the DDclient (3.7.3 under Ubuntu 8.04) on occasion would use the 
Gateway of the "Old" Provider and consequently use that for its IP Address 
Determination and update my DynDNS Entry accordingly!!!  Effectively 
"Flapping" between Providers, switching back to the "New" Provider 5 
Minutes after updating the DynDNS Entry to reflect the "Old" Provider's IP 
Address...

Although I have now disconnected the Router for the "Old" Provider from 
the LAN's Switch and expect the "Flapping" should stop, I am curious to 
know by what mechanism the DDclient would have been able to "Discover" the 
Second Router (Provider) without that being specified as a "Static" 
Gateway???  To my knowledge I am not running any Routing Protocol Services 
on the Ubuntu Server...
