Problems connecting to servers hosted on wingate PC

[danzeal]

I am hosting a game server for some older game (JJ2).
Using ports 10050 - 10060.
This is how the configuration for my server looks like:

OS: Win7 x64
NIC 1, NIC 2, NIC 3, NIC 4 and NIC 5 is connected directly to the internet.
NIC 6 is connected to the LAN.

Wingate shares NIC 1's connection to NIC 6.
All computers connected to NIC 6 has working internet connection.
But I can't join my game servers that is hosted on the server.
If I use the server PC to connect to any of the games using NIC 1, it works.
I can connect to other game servers even if I host and use the same NIC on some other PC, using same IP and is not connected to the LAN.
Sharing files from the wingate PC to the LAN works without problems.
So how should I configure wingate to make the LAN able to use the games hosted on the wingate PC?

Hi

those 5 NICs with internet connections - how are they connected? What sort of internet connection are they?

Normally this will cause a number of routing problems, since by default windows chooses the default route with the lowest metric for all outbound traffic, including response packets received on other connections. This causes packets to go back out the wrong interface.

Also, what OS is this on?

We've had some success in the past if you can get all the default routes to have the same metric.

Thanks for the reply.
External NICs is connected to a switch which is connected to 100/100Mbit fiber.
OS: Windows 7 home premium x64

How to change those metrics?

[adrien]

any particular reason you need 5 NICs? 1 NIC will handle that fibre bandwidth, you could assign it all 5 IPs. That could quite possibly solve the problem, since you'd only be dealing with 1 interface and 1 default gateway.

[danzeal]

Would be nice if that was possible, but the ISP/DHCP dosen't allow me to set a static IP.

[adrien]

so does that mean the connection is PPPoA, or PPPoE? Do they show up as dialup connections?

To change metric, normally edit the advanced TCP/IP parameters for the adapter.
