No, I haven't configured the Exchange server for use with the Dachstein router. I assumed that since the firewall had an internal address that the Exchange server would accept connections from it. Currently Exchange is configured to accept unauthenticated connections. > Is the Dachstein router replacing a prior router of some > sort?

I am still running a Proxy Server 2.0 at that address and it shows port 25 and 80 being open. Running a port scanner from outside the network against the Dachstein router shows only port 80 (and 22) as being open. You can try scanning against 216.70.236.236 (Dachstein) and see for yourself. Try the same scan against 216.70.236.235 (the Proxy Server) and you will notice that ports 25 and 80 are open. All evidence points to the Dachstein router. Ray, I understand what you're saying about the firewall being correctly configured- it does seem like it is. But the port scanner isn't reporting port 25 as being open. ~Doug ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html
