NFS mounting and routing question

[Hanry Zhou]

CLIENT IP-1: 15.200.20.20
SERVER IP-1: 15.200.20.21

in this example, if I made the client to send NFS packets via the router 15.200.10.1, not the default GW, then when the server returns packets back to the client, will these packets go through the same router "15.200.10.1" then back to the client?

[Dave Olker]

The server extracts the client's IP address from the NFS request, looks at its routing table, and selects the most appropriate route.

The only way the server would send the reply back through 15.200.10.1 is if that route is configured on the server and the routing table instructs it to use that route instead of the default gateway for the subnet.
