Change Exchange 2003 Standard Change IP for E-mail and OWA Usage?
Hi EE Kids,
We have a T1 circuit with two public IPs. One IP is for OWA and the other is incoming/outgoing e-mail. The T1 and our e-mail filter are being replaced. I need to migrate OWA and the filter off that T1 to a new circuit. We are using Exchange 2003 Standard.
220.127.116.11 is used for OWA. After NAT it goes directly to Exchange.
18.104.22.168 is our MX record for mail.mybiz.com. After NAT it goes to our e-mail filter then the e-mail filter forwards it to Exchange.
What would I need to change in Exchange System Manager to make the changes successful so OWA still works and incoming/outgoing e-mails send/receive from the new e-mail filter? I know I need to talk to our ISP about changing the sub-domain IP for OWA and the MX e-mail record. Does the ISP need to do anything else? When I tell me ISP to make these changes does it really take 2-3 days?
All I see in ESM is Administrator Groups -> Routing Groups-> Connectors. With a Connector pointing to our e-mail filter.
