I understand, I have set up many Mitel Firewalls before. It's just this time I am having issues. First it was "Error adding IP input Rule: Invalid IP." I knew I had it correct, Then it tells me "Error adding IP input Rule:" Error executing command" below it says "No rules are defined. Accepting all packets. Yes, you would do this on the router firewall, but I don't trust other peoples IT providers. I like to make sure the phone system is solid.
