Port 80 Blocking

ckwast · Post by **ckwast** » Fri Jan 18, 2008 9:40 pm

I have found out that my ISP, Cox Communications, is blocking port 80 incomming and MJ can not make a proxy connection. The IPS has stated that they would not unblock the port.

Is there any way around this problem? Can MJ use an alternate port?

"to protect our customers, upstream bandwidth, and the rest of the internet". They state it to protect from Web Servers and worms.

Oh wait, i recall when i had Verizon FIOS (Fiber optics) they blocked of port 80 too. But what really sucks is comcast is slowing down my torrents, but not blocking it. So that they are doing to prevent illegal downloads and stuff... people are noticing and they are getting the people up tom invloved...

Yes, but in this area i have no choice...flaws everywhere....my reccomendation to ckwast is to find a different ISP that keeps port 80 open...Or refresh your wireless networks and see if any of your neighbors have a open network...Then check and see if magicjack works off of it (should be a diff ISP if it does)

(p.s Sorry thats all I can think of)

Somehow that sounds slightly illegal...

Many ISPs block port 80 inbound. They do it so you can't run a web server. It would not affect MJ, my ISP blocks port 80 and my MJ works.

I gleaned this from the MJ WEB Site:

MagicJack uses ports UDP 5061, TCP 80 and TCP 443.

PS - The suggestion to change ISP - in anyplace I have ever lived it is just not that easy. I have found that for any given area there maybe cable and DSL and generally Cable is a better deal for the price and speed and if you can getDSL and at a good speed you are lucky. These ISP(s) usually don't crowd into a neighborhood giving you all kinds of competitive choices it is more like you are stuck with one ISP, maybe one and a half.

Example Qwest advertises 7 mbps DSL in my area but when I plug in my telephone number they say the best they can do is 1.5 mbps. I would hate to give up my 6 mbps cable for 1.5 mbps DSL. Free phone or not that would be as bad as going back to dial-up

It would be no contest for me, MJ would lose, I would only give up my 6 mbps Cable at gunpoint.

I believe the TCP 80 & 443 are OUTBOUND (i.e., for "Provisioning" and for the Ads). And I believe it is UDP port 5070 Outbound to the Proxy.; and UDP 5060 Inbound for SIP. If anyone believes this to be inaccurate, please chime in.

AFAIK you don't need any "Inbound" port open at your Firewall (for MOST Firewalls) w/ Magicjack because it is smart enough to initiate everything on the outbound conversation. (See http://www.phoneservicesupport.com/post1849.html#1849 for a basic explanation).

If it was necessary to open these ports Inbound at Firewall, we would ALL have to have "Port Forwarding" setup to forward 80 & 443 AND we would only be able to use ONE MJ per network ... and that is not the case.

Look into your Personal Firewall if you have one running ... I think the issue may be there or elsewhere.

testing123,

You are way over my head on the port specifics. I don't know how it gets thru my router but I didn't have to change anything in the Dlink Dir-655 and MagicJack just worked. My routher does have a SIP enable check box (I don't have a clue what it does other than it is related to VOIP) but someplace on the MJ WEB site I read they suggested you turn it off. So I tried it both ways and it didn't seem to make any difference.

The only reason I was even in the router at all was I love to hack and see if I can squeeze just a little more RPMs out of everything not that MJ was not working. And by the way for what it is worth the need for speed and blind tweaking can sometimes be a very painful experience when you kill a MagicJack black box, or some other nifty software/hardware item that I just can't seem to keep my fingers out of.

PS - @ Testing123 how in the hell did you reply to my post so fast. I hit the submit button, blinked and there was your reply. You have to be a 120 words/minute typist!

I understand the feeling and the desire ... I like the tweaking (testing) thing too. For MOST people, the Ports stuff should just work out of the box w/ MJ (WHEN THEIR SERVICE IS UP & RUNNING). That is one aspect of MJ that works well (i.e., the Port mumbo-jumbo).

Where the Ports stuff can come in handy though is for QoS (Quality of Service if your Router has that capability) so that you ensure sufficient Bandwidth and low Latency for MJ packets -- result: clear audio w/o the "choppy-ness".

Yeah, we geeks spend way too much time typing and not enough time doing real-life things. LOL

I'm confused here. Port 80 is the standard port for web traffic in and out so how can they block port 80 without shutting down everyone's ability to run a browser on the web?

GaryBritt,

This article would seem to confirm your statement. The way I read it no port 80 no access to a website.

He's talking about Port 80 INBOUND into your Network. When you are browsing you are making an OUTBOUND Connection AND you don't necessarily use Port 80 on your browser even though you are connecting to Port 80 on external Web Servers.

Example: When you browse "www.cnn.com" (default: Port 80), your browser may open an IP socket (IP connection "channel") to the cnn.com IP using TCP Port 32745 Locally which talks to cnn.com Port 80 Externally.

If your ISP Blocks TCP Port 80 that would usually refer to blocking InBound Port 80 requests (i.e., if YOU are running a Webserver on your local network) -- you would still be able to browse external (Outbound) Web Pages.

If running Windoze or Linux, use "netstat -na" to see what ports have been opened (and what direction) on your PC.

here's another nice little tool I like to use. Pretty much the same thing as netstat but with more info. Plus it's free!

I also have Cox for my ISP and they also block port 80, as do most ISPs. Doesn't affect MJ.
