Bug Selecting Interface based on Destination IP address

Hi all,

How an interface is selected based on the destination ip address.


Thanks in advance........

this only works if the two interfaces are in the same subnet and the other is not.

hai duke,

i don't think so, for example a host has two interfaces one is connected to lan and the other to internet, then how will select the right interface to reach u r destination.

for this the "defaultrouter" or "defaultgateway" setting is used... if you ping an address in your lan, the interface in your lan will be used. if you use a internet ip (and the defautroute points to your router) the other interface will be used...

have a look here:

if u r default interface is selected as lan interface and if u want to send the packet to the internet(destination outside the lan) then which interface will be selected.(source address is 0.0.0.0 -----binding is not done)
