I have a topology where my machine sends tftp traffic to tftp server[linux machine] on one IP address and receives reply from another IP address [2 NIC on tftp server] and there after uses second IP address for entire transfer. but i want to know how can i configure this rule[on tftp server] that when it replies it should be from second IP address.
what kind of rules do I need to configure is it IP tables? please assume the routes are configured on linux machine.
