Which adapter did I just receive this UDP packet?

Question

I am trying to write a BOOTP server in C #.

I receive and parse the BOOTP packet from the client, and I need to respond to my server IP address.

The problem is this:

• A computer may have several network adapters
• The client does not yet have an IP address

Is there any way to find out which adapter received the UDP packet?
