Hello, i have a new Router - the DLink DSL-2641B with Firmware EU_4.01 Hardware-Version: B2. Behind the router is an Linksys PAP2. My telephone provider is sipgate.de One time - my telephone runs ok - but only for 1 day. I made screenshots from the router and the pap2. What shall i do. The pap2 have an static ip - 192.168.1.6 and this ip is in the DMZ of the router. Also i have put the filters on the ports - no effect. Please help - any suggestions?
