Default Connection Problem

Hi all, I am not sure exactly which forum to post this in so I will try it
here. Two servers involved, both are running NW6.5SP5, one of them has
BM3.8.

Server-d has a private IP of 10.10.1.5 and is running a program that we need
to access from outside of that network.

BM server has a private IP of 10.10.1.9 and a public ip address of
XXX.XXX.XXX.144. NAT is running on the public card and has XXX.XXX.XXX.145
resolving to 10.10.1.5.

We have a software program running on 10.10.1.5 for an alternative school
and wish to access it from our main LAN at the high school. I had to send
the company some config files and open up some ports. They are making a
"client cd" for us to install with at the high school. I put in the
necessary filter exceptions to allow the ports and they cannot access port
3306 which is what the sql is running on. I took the filters totally down
and they still can't get to it so I don't think it is filtering. I then
turned off the Symantec firewall, so that is not it.

If I am wanting to get to port 3306 from the outside, what could I be
missing. You can type either public ip into a browser and it brings up the
page, I can get to either one and run imanager and remote console. Filters
are down, firewall is off......any suggestions???

Thanks,
keith

Let me see if I understand what you said so far:

1. No filtering up, so filters are not the issue.
2. Static NAT is enabled.
3. You can access the internal server from the outside, so that means
the secondary public address is there, static NAT is working, routing is
working, and the internal server has a correct default route.

My guess is that you are doing something with a web browser that
involves a redirect coming from the internal server. That redirect is
embedding the server's private IP address, and so when the external
client tries to get to the server, it doesn't know how to send the
packets to it. Not a port-related issue at all.

In these scenarios, you must configure the application to use a DNS name
instead of an IP address. The DNS name must be available on the public
and private sides. The public DNS must point to the public static NAT
address. The private DNS must point to the internal address (though you
can cheat here by putting the name and private address in the BMgr HOSTS
file if accessing via proxy).
