Hi Joseph, I didn't cover any back to back DMZ scenarios other then the unihomed Web Proxy for OWA publishing. Where is the SMTP relay located? Thanks!

It is amazing that from some sources I receive in email just fine on my own servers, but when I switched my isalist account to my own servers I received 3 emails then none, I'm unable to receive those items and had to switch back to my msn.com account. I would rather use my own mail servers. I made sure that I did not have SMTP 25 packet filters set and also made sure that protocols were set. I must be missing something. I will have to adopt the Missouri attitude. If someone has a simple Visio diagram showing the inbound from external isa > DMZ > Internal ISA sample setup please email it to me. And, what the possible protocols should look like I would appreciate it. Thank you, Joseph ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
