Dynamic and static IPs to the same domain

[Mol]

We´ve got a Win2000 Server as a proxy and a NT4 Server as a fileserver and DC. The proxy supplies the computers on the local net with IP-addresses.

All machines using DHCP can browse the network, seeing other DHCP-machines, but we also uses some static (public) IP-addresses, that also needs access to the machines using dynamic addresses.

How do we get this to work? Today, the fileserver has a public IP, and is plugged in directly to the switch (connected to a router).
The FS has a snd NIC, going to a hub where the proxy is taking care of the dynamic addresses.
The only way I can get the public addresses to work is to plug them in directly in the switch (same as the fileserver), I can´t use any public addresses in the hub on the other side of the proxy.

Is there any way around this? Maybe we´ve just forgotten to turn something on in the proxy...?

Presumably the DHCP clients are using a series of IP addresses in a different range to the clients with static IP addresses?

I would also assume that the Master Gateway set in the IP stack of the static clients would be the other NIC in the Fileserver that appears to be acting as a router.

If this is the case, then maybe IP forwarding isn't activated on the dual-homed fileserver - that would explain why one network can't see the other.

I hope I've read you correctly

Thanks CE,
The dynamic IP addresses aren´t in the same range as the public addresses.

Yes, the snd NIC in the fileserver has a static, public IP.

IP-forwarding is "checked" on the fileserver. If I put a cable in the switch (connected to the router to the Internet) I am able to resolve name of the computers using the dynamic IP addresses.

Do I have to enable some sort of "static route" to be able to connect computers directly to the switch instead of to the hub on the local net?

Is the Gateway configured in the client's IP stack?

As long as the clients can see the Gateway, and it can see both networks, then you should (in theory) have a connection!
