Macintosh Routing Problems

By larryrh ·
I have a G3 Mac on the same TCP/IP network, (mostly windows NT) that is working fine. I can use Microsoft Mail Exchange and also use the Proxy server to surf the intranet. Now when I moved the Mac to another subnet, using a NT server as the router, not changing anything on the Mac, the Mac now can not use the proxy to get to the internet. The Mac is using DHCP and has a good address for the new subnet. I have tried using Mac-ping to ping the proxy, I do get a reply. When I use trace route to the proxy it also gets a reply thru the gateway. When using IE4.5 for Mac?s, I get a ?HTTP Error 403?, ?403.6 Forbidden: IP Address Rejected?. The new Mac address of the new subnet is in the "LAT" table on the proxy, also other windows NT pc's on that subnet are all using the proxy server without any problems. I also have modified the host file on the Mac to define the address of the proxy server. The Mac is using os9. As I said works just fine on the same subnet as the proxy server.

Macintosh Routing Problems

Some questions for you.

Is the NT PC that is acting as a router enabled to route Appletalk or Ethertalk? Is it enabled to tunnel appletalk in IP? Is it running the Ethernet_II or Ethernet_SNAP frame type?

If you answer these, you may solve your own problem.

Yes on the route Appletalk and also rip for tcp/ip. Don't know how to enable tunneling apletalk! Using nt4.00 tcp/ip for the router. with seeding turned on to both nic cards.

I know this is not going to seem like much of an answer considering you cannot get to the internet, but have you updated your OS reciently? There are some known issues with Open Transport 2.5.2 (original OS 9 version) and Macintosh has a newer version out. OT 2.6 fixes several issues with TCP/IP. This is free from Apple's home page

http://asu.info.apple.com/

Hope this helps.

I checked out the open transport, it's 2.6.2. Also applied the the patch 9.04 for the os. also did not help.. I brought the Mac back to this side of the router and the Mac still connects to the internet, go figure. The problem is on the NT 4.0 router not passing the Mac address but can't find the correct answer to fix the problem.Thanks

Long shot but??

Have you looked into the proxy settings on
I.E. ??

Consider trashing the TCP/IP Prep file in
the system folder, and TCP/IP Pref. file in
the Prefrences folder and restarting.
Appletalk should not be in play for this
issue.

Sometimes, when Macs are moved in a NT Network, the Mac will switch to another Mac zone, do you have more than one Mac zone?
One what subnet is the Seed Router located?

Yes, there's two zones now. I added the second zone to see if that would fix this problem. It didn't...The "seed router default zone" is on the second subnet. The seed router is on the subnet that the mac's will not connect to the Intranet. This has always been this way. did not change that at all. The "seed router" is also the same NT router that separates the two subnets. Keep in mind this has never worked on the second subnet, Mac's getting to the Intranet. The Mac's do change Zones depending on which side of the router they are attached. If you have read the past answers, other NT PC's can get to the Intranet fine from this second subnet.. Hope you have an answer!!!

You must be pretty frustrated by now. :-)

This is just a shot in the dark since you've probably checked this already but have you tried using different applications, i.e., Netscape Navigator? You said ping and tracert work so everything seems fine and dandy up to the network layer. . .

There's been a lot of good ideas posted up here. The only other thing I can come up with is double check your Internet control panel for conflicting settings and if available try using earlier versions of the Mac OS to see if you can duplicate the problem. (Not that you want to duplicate the problem but you know what I mean :-)

Tough cookie to crack. Good luck!
