machine with multiple IPs how to set source IP for certain traffic?
Posted on 2011-03-24
I have a question regarding routing and IP addressing on a host. I have a particular situation that I'm trying to resolve.
I have a partner company that has a very strange network setup in which requires us to use a secondary NAT address before our traffic leaves our system. Depending on what NAT address we send as our source, will depend if we have access to a resouce on the other end. Due to even more complexity there's situations that a certain NAT say 10.0.6.1 cannot talk all the hosts on the other side of the tunnel.
My question is this. If I assign two IPs to my NIC card say 10.0.0.1 (primary IP) and 10.0.0.2 (secondary IP) and I have a host that I'm communicating with such as 10.0.6.10. in order to get access to that host I need to send to 10.0.6.10 as 10.0.0.2 instead of 10.0.0.1 how would I accomplish this? I'm assuming I could somehow add a static route through windows but not sure how. Any ideas?
