I've got a Tandberg 6000MXP on the inside of my network, this is NAT'ed out on the internet and all ports are opened for initial testing purposes using this command:
permit ip any host 18.104.22.168. (IP has been changed)
If i get a call in from a external system i get connected and the external guest can see picture from our VC unit, but we cannot see the external guest.
Are there any settings i can check? Or anything else i need to do on the router side?
