Cannot change gateway on two different interfaces?


I'm working with a 9111-520 and I am trying to set the gateway on en0 to 10.0.18.1 and on en1 to 172.31.1.10. However, upon changing the gateway on one interface it automatically changes the gateway to the same on the other interface. Why is that? It seems to me that if I have two separate interfaces that I should be able to set the gateways independently.

If you use the "lsparent -C -k ent" do you see a ent2? Are your adapters using Link Aggregation for either failover or load balancing?

No, I see ent0 and ent1.

Quote:
ent0 Available 09-08 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent1 Available 09-09 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
And then we have the interfaces associated with the adapters -

en0 Available 09-08 Standard Ethernet Network Interface
en1 Available 09-09 Standard Ethernet Network Interface
I'm not using link aggregation for this setup.

Do you have the "Dead Gateway Detection" active?

No, dead gateway detection is not enabled.

I'll explain what I'm trying to accomplish here to hopefully make this a bit clearer.

I'd like to use en0 on the 10. network for client access to the box. I would like to put en1 on the 172. network for any remote access. For example if the vendor comes into our VPN concentrator, they would then SSH over to 172.x.x.x . This would allow me to disable en1 and prevent remote/vendor access unless we were aware of the logging in. It may be easier to prevent access at the user level, however, trying the other way makes me curious as to why I cannot have two different interfaces on two different networks. (it could just be my lack of networking knowledge)
