We have a Mitell Border Gateway in our DMZ configured to accept teleworker connections. I have it all configured, but I get one way com errors on the Mitel border gateway when i try to place a call to a teleworker(phone set up outside the firewall). The teleworker phone cannot hear audio from the internal phone. I was told by vendor all ports need to be open to the border gateway for it to function. It seems that for some reason tcp traffic headed from the dmz to the outside are beng blocked and I dont know why. Should tha traffice be allowed by default? What rule do I need to allow any traffic coming from my MGB IP to use any port to talk to any device on the outside network. I already have a rule allowing all IP traffic in through the nat'd address fo the MBG.
I have this problem too.
