Architecture question...can this be done?

All,
I have a question about setting up sql server in a particular
architecture. Below is a diagram of my situation:
[sql server] [XYZ server]
[clients A] -- [nic #1] [nic #1]
-- [clients B]
[nic #2] -- [nic #2]
The A clients can see the sql server fine. However, I want the B
clients to see the sql server also. The connection between the two
"#2" nic cards must be over a single tcp/ip port for security reasons.
Is there any way to do this? I am trying to avoid putting another
replicated sql server on XYZ server.
What about a proxy app on XYZ server? Couldn't I some how set up a
proxy to redirect a tcp/ip port traffic to the sql server? Is this
possible:
1. Set up the sql server to listen to both it's NIC's IP Addresses on
Port 1443.
2. Client B requests a connection from XYZ server's
NIC1_IP_ADDR,Port1443
3. The proxy redirects traffic to NIC2_IP_ADDR,Port1443 ... ?
Am I on the right track? If anyone has any other suggestions in
solving this problem, I would really appreciate it.
Thankssorry my diagram was to big:
[sql server] [XYZ servr]
[clients A] --[nic #1] [nic #1]--[Clients B]
[nic #2]--[nic #2]|||Have you asked your network folks to use the route add command to configure
a route between clients B and sql server?

No I have not. I looked at the route command and this is the command
for route add:
route ADD 157.0.0.0 MASK 255.0.0.0 157.55.80.1 METRIC 3 IF 2
destination^ ^mask ^gateway metric^ ^
Interface^
I am pretty sure the destination would be ip addr of nic#2 on the sql
server, but I am not sure about the other two parms (mask and
gateway). I assume that mask would be the subnet mask that could
identify the destination (nic#2 sqlserver). I am also assuming the
gateway would be nic#1 on XYZ Server, since it could reach the
mask... Am I on the right track?|||yes, you are correct. Your network admin should be able to help you here
though.
