Firewall questions - a phone device Positron - is in the DMZ but I want to only allow certain IPs
Posted on 2014-01-30
a positron? phone system is on the lan. someone put it on the dmz - it needs to get data? from the Voip provider? but others are hacking into it. the voip provider is saying to white list their IP addresses.
a) can't do that when it's in the DMZ, right?
b) moving it back behind the firewall, I need to know what ports to forward to it, right? they should be able to tell me that?
c) then I have to hope the router will allow enough port forwarding rules?
