Firewall's being a bitch

What I'm thinking about, is like this is the problem if I make it really watered down from networking specifics..

Think this way, since you guys have experience with VRS/MVP/etc.

How do you get someone with a 56k modem to work on a videophone? Let's say the 56k speed isn't the issue, the issue is how to make the connection work. How do you go about to work on this?

The IP address changes frequently, all ports are opened unless closed privately (on the User's end).


Example...
When you use a cellphone to browse the net, your incoming data may work like this..

Mobile user:
accessing blahblahblah.com/picture.jpg
GET request from: 101.21.31.41 (mobile user)
GET request from: 101.21.31.42 (same mobile user)
GET request from: 101.21.31.49 (same mobile user)

Commercial broadband user:
accessing blahblahblah.com/picture.jpg
GET request from: 166.22.33.43 (commercial broadband user)


Now you want to act as a server for the broadband user:
Simple! All you have to do is make sure the internal NAT for the router (192.168.0.1 for example) has external ip 166.22.33.43 has port #XXXX opened for whatever you are trying to open right?


Now you are going to share your mobile connection (like act as a server)
The client wants to get from 101.21.31.41, but when it reaches that connection, it's incorrect.

How do you go about to solve this problem?

This is the issue that I'm seeing here.. the only alternative I can think of is dyndns to forward them all to an address. But I could be wrong. This is how I am seeing the problem is why the VRS user can't see Jclarke.
 
Believe it or not, YES Tmobile actually uses NAT addresses, it is 10.xxx.xxx.xxx format and it is buried deep and it is THERE.

Virtually ALL cell phones, pagers, and devices uses IP addresses EVEN Videophone will always have IP address

Problem is, this isn't a standard NAT device.. The ISP seems to be a cellphone provider (like Tmobile) as the connection is based on 3G. There is no private IP address, I think.. so that's why I erased my post containing ports to open.

It is basically mobile broadband, not the same as commercial broadband. That operates on a modem. This is somewhere that I've seen, but I've never dabbled in myself personally, so I am by no means any expert in this area. From basic understanding though, that's how I surmised a problem with the IP not being static, the main problem seems to be with the outgoing connection because the listening client won't have a static IP to work on.

Now your talking, it has IP addresses. It is really impossible for any electronic devices communicate though networking without IP addresses.

Sometimes ISP can be cheapstake and uses NAT address as having Public IP address is very expensive investment. .

The reason why 56K won't work, technically it CAN work, but you will get real choppy video, frequently freezes... Yet you CAN get incoming calls!

Well, I am here based on my experience and indepth understand of how Videophone works (Actually, I do this for living) Like I said in the past I DO see some ISP trying to be cheapstake by saving money and using NAT to spread out the cost. This usually happens in small time ISP. I have know few locations in the United States that offers broadband Internet connection, true business Ethernet cable running across town to customers. Every customers in that town gets private IP address, not public IP address, and in order to get Public IP address available, the fee is 75 dollars a month on top of basic service. I have seen that.

Anyway, what is most important is not to run around like a chicken without a head. GET the information first, I always ask for information so I can figure out where went wrong. In order to find out, it is fairly easy for Jake to find out. Go on Command prompt type in ipconfig /all then check the default gateway address, this is what will tell you whether ISP is using NAT address or not. If it is, then that is the problem and you would know where to look for.

Based on my experience, the problem usually is so small that one easily forget to check this out. So I tend to think small and collect information :)

I am thinking that you might want to contact your ISP administrator to see if someone would help you with that. Maybe, it has to do with the ISP server's firewall problem, not your computer.

Another thing, maybe, you might format your OS because it could be messed up somewhere in your laptop's system. After cleaning up your OS, you would find something easier for you to solve your problem with less complicated configuration or your own settings. Good Luck.

The laptop has been reformated twice in the past, it is the firewall I am concerned about.

si...si....




and by the way, I left my modem at home today so I wouldn't be able to investigate a little bit furter until tomorrow. ARGH!
 
Hello Jake, thank you for sending me your IP address snapshot. What I see is that the IP address assigned to you by ISP is 10.xxx.xxx.xxx that means you are behind ISP's own NAT. It has firewall built in, the only solution you got is to find out what port is needed to forward to your computer, then ask ISP to open port for you. Sometimes ISP will charge this as gaming service fee. Hope you won't have to pay for the fee.

Curious, were you guys able to get this fixed? Nice if so!

I am interested in knowing the results so I can put the knowledge on how it was fixed to future use, incase I come across future people with similar problems ;).
TIA - Thanks in advance.

You are not the only one. :cool2:
 
Hello, at this time, nope. Their ISP technican claims that there is no firewall, I think it is baloney. That is one problem, there is second problem, which baffles me. Of course the lappy IP address is in NAT category, but the gateway, it shows 0.0.0.0. That was static IP address. I wasn't sure if it is good idea to go ahead change to DHCP, if we go ahead then he may lost the Internet connection.

I wasn't sure why this shows that way yet he was able to surf the Internet. My hunch and based on my experience, it is his ISP the issue. He may be out of luck, and I sure hope I was wrong. Please remember that this wireless USB is more of reciever not modem/router. That is why I still am pointing at ISP.

Problem has been solved, the modem thing doesn't have router settings inside, and I went to the store and found a 3G mobile broadband router which connects with the modem and you will be able to access to the interface of the router to change settings and whatnot. I am currently setting it up and I have to mention, I swapped for a better modem from the store because the old one wasn't compatible - D'ohhh! But the good thing is that the new one is more faster now :)

You can configure port fowarding setting for MMx software on your new router.

Nathan fixed the ports for me, so I will do a test call on Monday via the new system

Great! he fixed it into your pc by CrossLoop? right? I hope that working to view VI on MMR on Monday.
