Client moved buildings and in the process replaced their old router. Now ActiveSync doesn't work on their iPhones. IP stayed the same. I can access webmail and OMA. Any ideas anyone?

Activesync only needs port 443 opened up and forwarded to your server.
What router is now installed and has port 443 been forwarded?
Some routers use this port to access the router remotely, so it may need to be reconfigured.
Port 443 is open. As I said, users can get to webmail and OMA.
