Trying to configure the new Broadband Phone Service with my Belkin N1 Wireless Modem Router F5D8631UK4A. Running Vista 64 with a Linksys CIT200 Cordless Phone and Kaspersky Internet Security 7 with SJPhone Ver 1.65 Have configured SJPhone & Kaspersky but in the status box at the bottom it says NAT/Firewall Blocked. Looks like I need to configure the Router and relevant ports tried entering for SIP * UDP port 5060 * TCP port 5060 * UDP ports 16384 to 32767 But still says NAT/Firewall Blocked even disabled Kaspersky, same result. any ideas?
I've posted this before but cant remember where - I seem to remember that Belkin devices have a SIP ALG somewhere and you need to turn that off to get around your device security policies. So despite having the right NAT or STUN settings you'd still get the same 'blocked' error until its removed. Im sorry to say that I havent a clue how you would turn it off - it may take a telnet session or could simply be a check box which you may of just bypassed previously.
