Routing Problem?

[sej111]

I’m trying to route Timbuktu connections coming in from my DSL WAN to a network Macintosh on my LAN. The network Mac has a reserved DHCP IP (192.168.0.14) and I’m using a Win. 2K Adv. Server.

I have Network and Internet NICS.

I tried setting the TCP/IP for the Network NIC as Follows: TCP/IP - Advanced - Options - TCP/IP Filtering - Properties - TCP Ports to 407,1417,1418,1419 and 1420 (Timbuktu primary port is 407, 1417-20 recommended by others).
I entered 192.168.0.14 in Wins (this feels wrong). Timbuktu couldn’t find the target Mac. Either the above isn’t correct or the problem is elsewhere, but I need to eliminate some variables.
Thanks in advance,
SEJ111

Are you using the Win2k server to do your NAT?

And are you expecting the entry you made to do a one to one NAT? or port redirecting?

To clearly describe your setup, use the term "public" for an IP address that is routable on the Internet. And use the term "private" for your private local LAN.

If you are trying to get to the 192.168.0.14 IP address from the Internet, it will never work.

I have a little SMC Router I’m trying to phase out and let my 2K server do all the work. To point Public Port 407 data at a specific private network machine using the SMC Router, you log into the SMC firmware set-up program, click “Virtual Server” enter the private machine’s LAN IP address and 407 into both the “public” and "private" port spaces...Done. When you connect to my Public WAN IP using Timbuktu from a remote location, you are routed right to the designated private LAN machine. This is the “Master” machine for outside Timbuktu access, the Timbuktu on the “Master” can then be used to access other machines on my LAN.

If what I’m trying to configure is a NAT then at least I know what I’m looking for, Thank You. If you could point me at set-up info, this would be greatly appreciated.

sej,

The TCP/IP filtering options should be removed, they are not forwarding entries like in your router. Just pretend that part of TCP/IP Properties does not exist.

Second, make the entry in LMHOSTS, not WINS.

Poke around this site to see how to get port forwarding under Windows ICS:

Unless I missed something, LMHosts led me to static mapping the Macintosh so the 2K server’s Wins could see it. All the Macs on my LAN have “Dave” installed so they are running NetBIOS (the server itself is also running PC MACLAN appletalk). The Macs and PC’s share all drives, printers, etc. Client for Microsoft Networks will access the Macs as easily as the PC’s. I went ahead and did it anyway (I also set filtering back to “permit all”). I’m using an AOL dial-up “Try Us” acct. for testing. Timbuktu still couldn’t get past the server - but it routes through the cheapo SMC router no problem. By the way, the website you suggested didn’t solve this problem, but did solve another with SBC/PACBELL DSL I was also having...Thanks.

I keep coming back to “NAT” and “Routing and Remote Access” even though it seems like a TCP/IP issue. I tinkered with activating Routing and Remote Access and my server’s DHCP died, I obviously did something wrong although I was reading instructions off a “Help” screen, so I deactivated it again. Networking has one hell of a steep learning curve doesn’t it. Any more suggestions?

Here is the port forwarding side of Win2k:

The Answer:
Two NICs, one Internet (WAN), one Network (LAN), Internet NIC shared to Network NIC. (If only one NIC, still the same? I don’t know.)

GO TO: Network and Dial-up Connections/Internet NIC, Properties/Sharing/Settings/Services/click Add, enter:
Name of Service: Timbuktu
Service Port Number: 407 (NOTE: I’ve heard Ports 1417-1420 are required for PC Timbuktu)
Name or address of server computer on private network: (Enter LAN IP of target private network computer.)

That’s it, thanks for steering me to that webpage, the answer was there. I deleted the static mapping for the target Mac and it still worked perfectly. I strongly suspect NetBIOS is also irrelevent, if the target computer is getting it’s internet from the server, that’s all the connection required.

Leave the Netbios alone

Glad it worked out for you.

Best.
