routing issue?

[rage]

I need another pair of eyes checking me on this. I'm not a networking guy, but trying my best.

I get 2 MB/s on average throughput when the NFS client in the 10.190.160.0 network is writing data to the NFS server. But when an NFS client within
192.168.2.0 network writes to the NFS server, I get gigabit performance as expected. Can anyone see a reason why?

vlan 1 vlan 1

| NFS client

| Default gateway: 10.90.160.129
| Static route to the 10.42.200.120 network)

Router
(FreeBSD gayteway/nat/ipfw
WAN: 10.42.200.120
LAN: 192.168.2.1
Default gateway: 10.42.200.96)

vlan 4

NFS server
(Public IP: 10.42.200.125
Private IP: 192.168.2.15)


Background info:

Everything is gigabit in this network. The NFS client is on a different IP network then the NFS server is.
I added a static route on the NFS client so that traffic stays on the local network.

1. Please put the netmasks for your networks on your diagram.
2. Where is the nfs server 'public' address - 10.42.200.125 - configured? Is there a second interface on the server, connected to vlan1?
3. How many physical interfaces does the router have? Is it a router on a stick (= one interface trunked to a switch port)?
4. Show us the nfs client static route definition, please.

By the way, 10.0.0.0/8 is a private class A network, as of rfc 1918.
