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

Can you ping the Mac from the Proxy Server when they are separated by the router? If the proxy can't send back the authentication to the Mac, that might explain why you are getting connections refused? I've also run into issues with the Macs and Proxy setup. I also noticed you use intranet and internet throughout your description of the problem: are you only accessing the internet, or are you accessing local internal web servers and hosts?

I think the issue is on your router setup. Although the PCs are working, it would appear that TCP/IP isn't working properly with your Mac and it's appletalk default protocol. WIth a PC, you can change the binding order...macs aren't as easy to manipulate. It will either use appletalk by itself,or tcp/ip by itself.

I understand your frustration: I would really take a harder look at the segements you have made, and check to see that you aren't limiting more than you need to between the two segments.

I'm not much help, but I just thought a fresh look at things might come in handy.

Good luck.

This has to be an issue with the access
configuration in either your proxy or the
website you are trying to access.

Does the HTTP error come from the proxy
or from the website you are trying to
access?

The 403 error is a client error, which is
returned if you try and access an area you
are not authenticated for. I suggest
setting static IP's on the mac, and see if
you get through the proxy. If you don't, try
and set the same static IP on a PC, and
see whether you are let through then.

If you are, then something really weird is
going on, because a router cannot see
any difference between TCP queries from
a mac or a pc, appart from the packet
size.

Also try and run debugging or auditing on
the proxy, to see how the connections are
recorded by the proxy. (Use netstat or
something like that to see whether the
incoming connection is actually
connecting to the proxy)

Try and configure static IP routes on the
proxy, and make sure there are no
conflicting routes anywhere.

If that doesn't work, try setting up a proper
router, rather than using NT, as NT's
routing services are quite bad.

I would try using a static IP instead of DHCP and also upgrade IE and the OS (which would be IE 5 and OS 9.1). I would say that for some reson the Mac doesnt like the Subnet/NT router combination.

The Mac is using a static ip and also using OS 9.1 now. I could not find IE 5.0 for mac but have the lattest of both IE and Netscape on the Mac.. I have installed a PC next to the users using Windows NT and the now can use the Internet.. Go figure, Macs do not like NT routers...
