HiCan we configure Edge transport server with one NIC on DMZ network, if we can then what could be network or network IP in send connector and receive connector (outbound & inbound) After configuring Edge transport with subcriptions what is the best way to test that our configuration are OK and mails from inside will go out and incomming mails will received by hub transport serverNagorimanagori

Nagori,It should work see this post:http://social.technet.microsoft.com/forums/en-US/exchangesvrtransport/thread/2604b68e-e6a3-4365-809b-44281fb4a776/If you set up the subscription the connectors are created automaticly. How you can test it, just send a mail from outside to an internal address and the other way and check if the e-mail arrives.Check this tutorial on how to set it up:http://johanveldhuis.nl/?page_id=697&lang=enRegards,Johanblog: www.johanveldhuis.nl
