PIX will not forward properly

[splicerguy]

Hey guys,

I've got a PIX515E.

I'm hosting services in both the Inside and DMZ networks.

In the DMZ I've got a DNS and Web server and both are accessible from the Outside.

In the Inside I've got an Exchange and test server. I cannot access any port on the exchange server (ftp,smtp, etc) yet when I set up a test server I can connect to its ports - in my current config its port 89 (a web server).

The exchange server is not blocking any ports since I can connect (from inside the network) via telnet to any of its ports.

Any ideas? Here's my PIX Code:

You try a clear xlate ?


pix# clear xlate <enter>

 

[splicerguy]

Tried it. No luck. I did a complete erase of the PIX config. Still no luck.

 

[brianinms]

Are you trying to connect to the public IP addresses from a connection outside your network?

 

[splicerguy]

Yes, I'm trying to connect to the public IP from outside my network.

 

[brianinms]

I dont see anything wrong with your configuration. I assume you have tested the exchange servers connectivity to the internet and you can telnet to it on port 25?

 

[splicerguy]

Yes, exchange server works fine. It's got internet access and I can telnet to port 25 without a problem.
