Please help me to configure NAT
  Posted by  Steve Zerobnick  on Wednesday, August 30, 2006 at 1:43:33 PM (EST)
Hi all

I wish for your help to configure NAT, since 602software guys don't want to help me with this, and there is no desent manual or step by step instructions.

I was using LS2004 as proxy server and now I want to use the NAT feature.

The instruction I found in the forum is this:
1. Access the TCP/IP settings for the appropriate interface on the client machine.
2. Change the 'Default Gateway' to use the 602LAN SUITE computer's internal (LAN) interface.
3. Add the appropriate DNS server IP addresses. These should be provided by your ISP.

I did it all, and also set the server correctly, but no NAT.

After I set all settings, I see at the log this line:
NAT: 0005 Route3

I have some questions:

a. server side
1) in addition to enable NAT and select NIC's, do I have to enable DHCP?
2) Inside NAT tab, there is a sub tab by the name of IP-Filter, do I have to set something there?
3) do I have to set something in the proxy tab?

b. client side
1) what to do with the Proxy Settings in Internet explorer settings, do I have to un-check the "use a proxy server"?
2) they said "Add the appropriate DNS server IP addresses", where to do this?
3) can I use auto DHCP, or do I have to use static ip?

No.

No.

3) do I have to set something in the proxy tab?

No.

Remove all proxy settings.

2) they said "Add the appropriate DNS server IP addresses", where to do this?

In your TCP/IP setup on the clients. The DNS servers will be provided by your ISP.

3) can I use auto DHCP, or do I have to use static ip?

You can use either.

So whats wrong?

I did every thing, and there is no result.

I get this "NAT: 0005 Route3" line in the log, and no access to web.

Maybe there is something in the ADSL modem?

The DHCP server is configured to populate range of address from 10.10.10.30 to 10.10.10.50

Please take a look at my IPCONFIG

---This is my "internal nic" I set the 10.10.10.100 ip address as the local address---

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 10.10.10.100
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :


----- this is the nic that is connected to the ADSL modem, parametes were given by the ISP -------

Ethernet adapter actcom:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 10.0.0.2
Subnet Mask . . . . . . . . . . . : 255.0.0.0
Default Gateway . . . . . . . . . :


---- this is PPPOE wan adapter, the ip address is my "real" IP address ------------

PPP adapter ADSL:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.115.xxx.xxx
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 192.115.xxx.xxx

-----------------------------------------------------

At the NAT configuration, I see the first and the second adapters (both are real adapters)

And internet is normally accessible form the pc running lansuite? You have no gateways set and I can imagine that might cause problem with routing. Try to set up gateway on your adapter connected to adsl modem (the internal IP of the ADSL modem - it's usually either 10.0.0.138 or 10.0.0.1)

Hi

Thanks for the reply

Well, The PC that run lansuite has a perfect connection to the internet (http, ftp ...).

I checked and found that the modem ip is 10.0.0.138, so I set the default gateway of the nic the is connected to the modem to this address, with no result....

This is the complete ipconfig /all result

Any other suggestions?
maybe to set a default gateway to the internal nic?
