Hello, I apologize for the multiple posting, but I'm hoping someone out there can help me. Does anyone have Spectrum as their internet provider? If so, do you have their newest Wave2 router? It's the RAC2V1A Arris (TR4400-AC). If all this is yes or you can help me anyway, I am trying to get out to my server and use asterisk. My internet server is cloud based and has a public IP address. My IP here is also public and maybe static I don't know it hasn't changed in a while, but the router see above gives out 192.x.x.x addresses as it should. Here's the question, the point to all this, I am trying to get sip going so I can do more than connect and disconnect and can actually here some audio. There's some passthrough options under advanced, > wan, > nat passthrough, I've got the relevant ones on they were on by default I dchanged them to off didn't make a difference so I returned them to the default values. My current theory and I'm not sure why this is needed with the passthrough is I have to forward a port range from the router to my phone, which has a dhcp-statically assigned ip address. How do you navigate that form? It is a nightmare and I don't know the values to put in it. Any help appreciated, if you think necessary please email privately. Thanks. Dave.
