Two networking cards

Hi there,

Here is an interesting question. We have two servers, each of them has two
networking cards, all of them connect Internet directly (two subnets,
155.57.19.xxx and 155.57.44.xxx), but only cards on 155.57.19.xxx sets up a
gateway, 155.57.19.254. My question is both cards on one of servers work
very well, computers on both subnets 155.57.19.xxx and 155.57.44.xxx can
access both cards, but one card on the other server works not well,
computers on 155.57.44.xxx can access 155.57.44.72, computers on
155.57.19.xxx can access 155.57.19.237, but computers on 155.57.19.xxx
cannot access 155.57.44.72.

Configuration of working one as
Windows 2003 Enterprise Version SP1
An Intel dual port networking card

Configuration of non-working one as
Windows 2003 Standard Version SP1
One Intel(R) PRO/1000 XT Network Connection and one Intel(R) PRO/100 S
Server Adapter

I don't know why one of them doesn't work. Is it networking configuration
problem, Windows 2k3 version problem or networking card problem? In fact, I
cannot figure out both two networking card connecting with Internet.

Please see the attached route tables, the top one is from working server,
the bottom one is from non-working server.

Thanks.

Wendel, sorry for confusion. I've given all information on 4 cards. All of
them connected Ineternet directly.

2 cards (in fact, it's a Dual Port card) on working one are, 155.57.19.210
with the gateway of 155.57.19.254 and 155.57.44.92 without the gateway (in
fact, the gateway of 155.57.44.92/24 is 155.57.44.254, but the gateway isn't
set because two cards are in win2k3 ). All computers on 155.57.19.0/24 and
157.57.44.0/24 can access them (including PING, we have file sharing
service). The OS is windows 2003 enterprise version SP1.

2 cards (two separate cards) on non-working one are, 155.57.19.237 with the
gateway of 155.57.19.254 and 155.57.44.72 without gateway either. Computers
on 155.57.19.0/24 can access 155.57.19.237 and those on 155.57.44.0/24 can
access 155.57.44.72, but 155.57.19.0/24 cannot access 155.57.44.72, vice
versa. The OS is windows 2003 standard version SP1.

The networking settings of the two servers are same (at lease I think), is
there an internal routing in a Dual Port card? Does 2003 enterprise support
more powerful on two cards? Or other setting I can configure? I never set up
a server with two cards before, so confused.

Thanks.

Ray

Ray,
Ok here is the thing you have a gateway of 155.57.19.254 Is this your
internet router?
do the workstations have this as their default gateway?
What is the gateway on the workstations in your 2 subnets?
This is key to understanding how the traffic is routed and by what.

If you want performance, load balancing or redundancy then you need to use
network teaming.
This gives you 1 virtual IP address over multiple network cards.

Yeah, the gateway of 155.57.19.0/24 for workstations and servers is
155.57.19.254 and that of 155.57.44.0/24 is 155.57.44.254, both gateways are
Internet routers. We wanna use them for load balancing not for redundancy.
Currently, it seems no routing between two cards in one server. What's
network teaming?
Thanks.

Ray,
What I think is happening is that your routers are routing all the traffic
between your subnets out through the internet and back in again. Unless you
have set up RIP or static routes on your workstations. Is that the case? Use
tracert to find out.
Network Teaming allows multiple network cards to share a single IP address
thus doubling or more your network bandwidth to the server. I don’t think
that's what you are after. Do you want to load balance the internet or local
network?

Wendel,

If so, it's weird, one of my servers works, the other doesn't. Is that
because it use a Dual-port networking card? And then is there a routing in
the card?

Although they are on Internet, in fact, I set up firework, only local
workstations can access them, so for the local network.

Ray,
It depends where the packets are being routed.
You really need to do some Tracert from workstation and servers in the .19
subnet to the servers in the .44 subnet and visa versa. Also tracert
workstation to workstation .19 to .44 subnet and visa versa. That will tell
you exactly where the packets are going and what is routing them.
It may be the dual port network card is routing packets, it shouldn't be so
may be that is the problem.
Do some trace routes and post them.

Wendel,

In fact, I did try tracert and said 155.57.44.0/24 could access
155.57.19.210 and could not access 155.57 19.72. Please see the following
result I tried on a computer in 155.57.44.0/24. Although I set up a gateway
(155.57.19.254) for 155.57.19.237, 44.xxx still cannot access 19.237. Please
don't be surprised 155.57.19.254 is the same router as 155.57.44.254, and I
cannot touch the router that belongs to the university.

Moreover, if I disable the card of 155.57.44.72 on the server, computers in
155.57.44.0/24 can access 155.57.19.237!

In fact, my problem may be how to configure two cards on a server. Thanks.
