Hi, I have Exchange 5.5 running behind Proxy server. Recently we have configured ISA EE in Integrated mode and it is running smoothly. I want to publish the same Exchange behind ISA and test the connectivity and communication; at the same time I dont want to divert all the SMTP traffice from Proxy to ISA. Is it possible to configure like mentioned? If yes, please provide me a detailed description. If not, please give me the reasons. I would appreciate your concern. Thanks Santhosh
