Network routing for exchange server are properly working traceble and pingable.
High TCP port are already defined in firewall (High TCP port number between 1024 - 65535)
Opened port 135 TCP

    Its not supported to have any firewall rules between Exchange Servers other then ANY/ANY

    Having said that, you should prob open 443/80 ports as well between the servers if they are not already
