Windows routing table

Hi all,

I have a single computer with a single NIC

I need to connect to device A from source IP A (default IP on NIC)

I need to connect to device B from source IP B (Alias IP on NIC)

I tried to create a route for the destination to device B, but when I set the gateway for that route equal to the alias IP, it defaults to “on link” and uses the default IP on that interface.

Any help?
