I am running Asterisk on a linux box in the DMZ of a D-Link 504g modem/router and am experiencing huge latency. The delay is about 5-10 seconds and results in an unusable service.
I’m sure its a D-Link thing because previously I used the linux server running asterisk for pppoe and dhcp so it was open completely to the net, and this worked fine.
I have changed my network arrangement due to over-dependance on the linux server in an effort to increase security and manageability.
I expected to have problems like this, but i’m not sure how to trouble shoot as the server is in the DMZ so it should be fine. I’m thinking perhaps its a problem with the phone with is a budgetone plugged into the D-Link so this device is not in the dmz…
