I have two domains in two separate forests i.e Alocal & Blocal. Both forests have their own Exchange& AD. We have connected both sites(One Public IP) and I can ping servers by IP on both ends. I can not send email from exchange server at Alocal to Blocal because the emails are considering Exchange server at Blocal as an external server. I have track the email & emails are going out of the network and it can not reach the Blocal because it has the same public IP.
I created a secondary DNS ZONE on Alocal DNS server & created a static entry for Blocal SMTP but still emails are going out of the network.
How I can make both exchange servers local so emails from *@Alocal goes directly to *@BLocal
