<div dir="ltr">Kamil,<div><br></div><div>The security model of FreeSWITCH can be quite complex, To blame FreeSWITCH itself for your misconfiguration is downright FUD, If you have issues or questions on how to properly configure FreeSWITCH for this specific role you can just ask, many of us will help you create a configuration that would be robust and secure. If you would have set 'disable-transfer', to true, and possibly 'disable-register' it would also help lower your attack surface, In addition you shouldn't open your system to the planet, thats irresponsible on your part for doing so.</div><div><br></div><div>FreeSWITCH isn't a firewall, so of course its weak because its NOT a firewall.</div><div><br></div><div>And these are in the configs:</div><div><br></div><div><br></div><div>

I personally faced two attacks where FS was not good at. And we lost a lot of money. It works perfectly as NAT between internal and extenal networks, actually in everything but it is weak as a firewall. Stanislav knows that, he helped me to resolve the problem first time when it happend. I cannot go into details as this is open forum. You need to put either kamailio or opensips in front of FS.</div><div class="gmail_extra"><div><div class="gmail-h5"><br></div></div></div></blockquote></div><br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">
