How do i get 2 different subnets to talk to each other?

cheater512

Hi

I have a main server (Windows) which shares the internet to my Wireless LAN and my second server (Gentoo) which is on a Wired LAN.

They are on 2 different subnets and to access the second server from my main computer which is on the Wireless LAN i need to TightVNC over to the main server then SSH over to the second one.

My internet connection (on the main server) is NATed (Micro$oft ICS) to the Wireless LAN. Currently my second server uses Squid on the main server to access the internet which is not good for a server.

As you can probally guess this is not a good way to administer a server or run one.

How can i get my Wireless LAN talk to my Wired LAN and get my net connection NATed to both networks?

Can you explain what your requirements are? I'm not clear why you want/need two subnets, why you're using ICS, etc.

Doesn't your wireless router provide NAT? Doesn't it provide a built in switch?

If you want to do internet connection sharing using a computer, why are you using ICS instead of the Gentoo computer with iptables and masquerade? How many computers do you have total?

No router. I use a Windows server to share internet.

My Wireless LAN and the Wired LAN are two different network cards in the main server.

I would love to make my main server Gentoo as well but currently I'm tied to Windows. :cry:

Enable routing in windows then

To enable TCP/IP forwarding:
1. Use Registry Editor (Regedt32.exe) to view the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

2. Set the following registry value:
Value Name: IPEnableRouter
Value type: REG_DWORD
Value Data: 1

NOTE: A value of 1 enables TCP/IP forwarding for all network connections installed and used by this computer.

Thanks a lot for that. Works beautifully :lol:

Only problem is the second server still cant access the net directly. I've heard that you cant have NAT running on 2 different adaptors for the same internet connection but there must be a way to get it to work.

Don't use ICS, try out a 3rd party app like WinRoute

I know you could do it on Windows ME, I'll have a quick looksee on XP...
