Re: [sipx-users] NAT Remote Workers

[Ewan McLean]

Oops, apologies. I must have misinterpreted what you said. It was this email that I was referring to: undo this: There's a home broadband router at .1 with various ports opened through the firewall/NAT for SIP. make sure that any sip ALG is off on the home broadband router.  sipx is already compensating for that, it will handle the nat, and you are not letting it. I undid the port forwarding and it started working so I put two and two together! No offence was caused, I just mentioned what you said to put my understanding in context. So I should re-enable port forwarding with the ports outlined on your diagram? There is no reference to ALG in the router interface so I assume it's off. Tony Graziano 29 September 2011 22:44 I don;t think you understand. I am sure you don't. I never said any such thing... I said make sure your firewall is doing symmetrical nat. I said if your firewall has a sip helper application (sip alg, proxy) turn it off. I said if the ITSP has a sip or nat helper to have them turn their off. This IS NOT THE SAME as saying DONT PORT FORWARD for sipx on the firewall. Don't say "Tony told me to do this. If you don't undertsand the directions, ask." Better yet.. here's a picture. http://blog.myitdepartment.net/wp-content/uploads/2009/11/Call-Setup-Example-sipXecs-through-ITSP1.pdf -- ====================== Tony Graziano, Manager Telephone: 434.984.8430 sip: tgrazi...@voice.myitdepartment.net Fax: 434.465.6833 Email: tgrazi...@myitdepartment.net LAN/Telephony/Security and Control Systems Helpdesk: Telephone: 434.984.8426 sip: helpd...@voice.myitdepartment.net Helpdesk Contract Customers: http://support.myitdepartment.net Blog: http://blog.myitdepartment.net Linked-In Profile: http://www.linkedin.com/pub/tony-graziano/14/4a6/7a4 Ask about our Internet Fax services! _______________________________________________ sipx-users mailing list sipx-users@list.sipfoundry.org List Archive: http://list.sipfoundry.org/archive/sipx-users/ Ewan McLean 29 September 2011 22:27 Hi folks Tony advised me before to disable port forwarding on my local router as it was interfering with the NAT sipx was trying to do. This solved a problem for me. However I am now trying to support remote workers and the wiki instructs to put in port forwarding. Is this safe to do or will it break my existing setup like it did first time round?? Cheers Ewan
