Exchange 2007 OWA on NLB not working from the internet
Posted on 2009-07-02
I am in the process of transitioning to Exchange 2007 and everything is pretty much set up. Except I can't get to OWA from the internet. This is on two server 2k8 boxes with network load balancing set up with the CAS role, two more servers with NLB and hub roles then two more with the mailbox roles.
I know, firewall, I've been all around accusing the firewall. But, if I set a public IP and open ports for an individual server it works great on the internet, atm all ports are open and it does work 1 out of 50 tries from the internet.
On campus everything works great I can connect to OWA using the NLB cluster IP. I'm thinking something is setup incorrectly with the NLB but I've tried every different config I could find. Anyone have any ideas?
