MJ incompatible with Verizon Security Suite in MagicJack http://www.dslreports.com/forum/r22604023 en Tue, 08 Dec 2009 21:36:10 EDT Tue, 08 Dec 2009 21:36:10 EDT Re: MJ incompatible with Verizon Security Suite http://www.dslreports.com/forum/remark,22629311 DrStrange : It seems to me that this would be handled easily by adding an exception [for both inbound and outbound traffic] for magicjack.exe to the Verizon firewall.

Here's a user guide to the Verizon firewall:

If you actually know how to use the Verizon Firewall then unblock these ports:
TCP Ports List: 80 (HTTP), 443 (HTTPS)
UDP Ports List: 5060, 5070
UDP 10000-65535 (I am not sure if these are necessary but people claim Magicjack will use a random port in this range.)
That's not entirely correct.

1. MJ only uses UDP 5070. But, it's common for people to open 5060 through 5070 because that's what the SIP standard provides for.

2. MJ uses a random UDP port in the range of 10000-30000. There's no reason to open ports above 30000.

3. This port "opening" should not be confused with "port forwarding."

Most people who think of "opening ports on their firewalls" think it means they have to allow access *from* the extranet into their local network (using "port forwarding"). Magicjack doesn't require that.

The people who get into trouble with firewalls are those in corporate (restrictive environments), or who use a simplified security or firewall interface, and choose "high" without knowing what it means. In both cases it restricts access *to* the external network from the internal network (except for some well known activities like web browsing on ports 80, 8080, 443.

It's *those* people who need to open ports to undo the restrictions they placed on themselves.

Caveat: There are a few rare circumstances involving Linksys routers with buggy firmware, where port forwarding (allowing external connections *into* the internal network) seems to allow the buggy router to work.

The only reason I'm sensitive to this topic is that I see the advice "open ports" given out so often that it causes MJ users to use port forwarding to open large (incoming) holes in their firewalls for no reason. It turns into an urban legend just because everyone's seen so many people provide the advice (without explanation).

The vast majority of people do not have restrictive firewalls prohibiting *outbound* access to the internet. That's the only time (except for some buggy newer Linksys routers) that anyone needs to "open ports."

At this point I was told that MJ is not compatible with Verizon Security Suite. This is never mentioned by MJ and in fact they state on their web site that they are compatible with firewalls. Sounds like another potential lawsuit to me.
you would have to pay an attorney in full in advance to take your case. MJ can't be responsible for the entire universe of other companies' service offerings and modifying their own product to be compatible with everyone else. too bad for you that MJ has both your money and their difficult to UNINSTALL advertising software resident on your PC.]]> http://www.dslreports.com/forum/remark,22626457 Mon, 29 Jun 2009 00:58:35 EDT Re: MJ incompatible with Verizon Security Suite http://www.dslreports.com/forum/remark,22604308 amigo_boy :

Myself and others use MJ with a firewall. You have to distinguish between a firewall that blocks connections *from* the extranet into your local network. And, a firewall that blocks connections *to* the extranet from your local network.

MJ works fine with the former. There's no need to open ports, etc. But, if someone has a restrictive firewall to prevent them from accessing the extranet, then you have to open ports. This is described on the magicJack wiki FAQ (»en.wikibooks.org/wiki/MagicJack)

I contacted support again and they tried a few things, then the chat was elevated to a higher level. At this point I was told that MJ is not compatible with Verizon Security Suite. This is never mentioned by MJ and in fact they state on their web site that they are compatible with firewalls. Sounds like another potential lawsuit to me.
