Dual NICs 1-Internet 1-Switch

Our compnay doesn't have an IT dept. We do however have myself and
another technician who are technically savvy, but this, we are stuck
on. We have a new server with 2 NICs.. One takes the internet from a
router. The other sends it to the hub/switch. Laptops connected to the
hub get IP addresses from DHCP, but they cannot connect to the
internet or PING any IP address. The server has internet.

Internet --> Router --> NIC1 # NIC2 --> Hub/Switch --> Computers

Router- 10.20.0.z
NIC1 IP- 10.20.0.x DG- 10.20.0.z
NIC2 IP- 10.20.0.y DG- 10.20.0.x
Hub- Unmanaged
Laptops IP- DHCP DG- 10.20.0.y

Help....

Thanks,
Joe

First question has to be, why do you feel you need to have two NICs in the
server to begin with? Unless you're running ISA or other proxy server, or
RRAS (which I wouldn't recommend generally), this is not a recommended
config.

That said, if you're going to have two NICs connected to two different
device they would at least need to be on different IP subnets. You're using
10.20.0.0 on both - this won't work. Then you'd need RRAS or something on
the box. Again, I don't recommend this unless you have some compelling
reason to use it.

I'd disable one NIC, plug the router into the switch, plug your server & all
your workstations into the same switch,and leave it that way. Your server
should be doing DHCP, usually (this is especially important if you run AD &
your own internal DNS server). This shold be a simple, straightforward
thing.

I agree 100%.
