<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Hello,<br><br>Sorry to ask like that but could someone points me to some site that explains exactly what I need to open towards the internet so that<br>my FS server is working while limiting its visibility?<br>




<br>since 1st of February I have an IP that continually sends me SIP Register request at a rate of 70KB/s. I have complained to my internet<br>provider but they refuse to help saying that the problem is on my side. I also logged a complain to the provider on that IP and am waiting on that.<br>




<br>At the moment on my firewall I opened port 5060 and 5080 (well now I blocked as well that IP) but I want to know if both are really needed or if I could block one of them<br> or may be limit the port to some IP. <br>
