Why does IP keeps on changing?

Can't see a proxy changing IP's in midstre......

Ah, ok, got it :o Will ask.....

Added:

Think I'm still on the right track. Those IP's are two different NAT engines, so it must imply a disconnect or two concurrent sessions.

Yep, what I meant was some sort of load balancing between two Proxy servers or clusters - ergo the alternating IP addresses seen externally, where the term Proxy Servers loosely translates into NAT Engines in this context...:)

I doubt it is due to disconnects|reconnections, also concurrent connections should be technically impossible unless [searchforum]DataSIM[/searchforum] is in play - even then it would imply 2 separate modems and [Data]SIM cards being used on the same PC - which is surely unlikely in pietpetoors' case?

If one NAT pool is full, it'll spill over to the next, but obviously only for the next connection. So it does seem to imply a disconnect.

Otherwise, the two concurrent systems is the next logical answer.

Ok, here is another spin on the disconnect possibility: let's assume [bcos pietpetoors has not provided the info] that pietpetoors is using either 2G-Preferred or 3G-Preferred instead of of say 2G-Only or 3G-Only, and further assume that pietpetoors' E220 experiences frequent switching between 2G and 3G, is it possible or likely that the NAT Engines would also switch with the switching between bearer networks?

@pietpetoors, please post which 'Preferred' or 'Only' setting you are using in the dashboard software...

Sorry guys, for some reason this forum do not notify me of posts even though I selected the option.

The issue above happens while I am connected.

I set the modem on 3G preferred. I have never seen anything about 2G on the display, did not even know that something like that exists. If I have a bad connection it might either go to GPRS or no network.

I had problems where secure sites (especially my server control panel) kept on logging me out. I then kept on logging in and work until the sites logs me out so that server admin could keep an eye on the error log and see why this happened. That is how they discovered that each time I log into the site I have a different IP. But the whole time while I did the test I was connected to 3G without being disconnected from the network.

What I find strange about the tracert thing is that I can view a site and it loads rather fast but at the very same time if I do a tracert it gives me all these time-outs, it does not make sense to me, if the tracert times out according to me the http connection should then also time out.

I might add, since I changed to the internetVPN I do not have the problem getting logged out of secure sites anymore and my ftp is working much better.

tracert uses the ICMP protocol and thus the firewalls won't allow it. THat's why you only get the last hop.

If you're 100% sure you don't get disconnected (and reconnect automatically) and you only have one session going on at the same time (can you confirm?), we'll need to do some traces with you. We've never seen this behaviour before and it goes against all normal rules.

Will need your help with that one. I connect to the Internet with my PC and the modem is installed on my PC. My wife's PC is also connected to mine via a network cable. So when I am connected she can also use the Internet.

Does that mean that she is also connected as a separate user or does the modem's connection counts as one connection?

So basically one PC connects to the Internet and sometimes more than one users uses the same connection. Does that answer the question?

Like v3g mentioned about ICMP packets, not all hosts|routers on the Internet will respond to a tracert, this is basic stealth firewalling so as to reveal as little info as possible to potential hacks.

I think what v3g means, is, are you using more than one browser session to login to your control panel? - for example, do you have two different browsers open and logged into your CP?
 
Ip

Seems like everybody lost interest in this topic.
Tonight is one of those terrible nights again. I get logged out again of secure sites, I cannot ftp, etc.

I am on the InternetVPN as suggested,
I have downloaded and installed the latest software and other thing for my Huawei Modem.
I did delete all cache in my browser
I did go to dos prompt and did the ipconfig/flushdns thingy
I have restarted my PC

But still I get nowhere. I wasted an hour now trying to get one single file uploaded to the server.
 
Still no reply

Still no reply.
Today is another one of those days. I cannot ftp my files onto the server, I get logged out of secure server due to my ip being changed all the time. Same old, same old.

If anybody who is ever so slightly considering getting Vodacom 3G .. DON'T. It is the biggest load of crap. If you need a stable and reliable connection, Vodacom 3G cannot provide that.

I never had these problems when I used Telkom ADSL the previous two years. After I moved to another town I had to take the 3G because I could not wait 8 weeks for ADSL. That was the worst mistake I ever made, I should have waited the 8 weeks. Because now I cannot work one single day without having the frustration of not being able to do what I have to do. I continuously having problems with not being able to upload my files to the server, getting logged out of secure servers, getting disconnected, being connected but having no data transfer. It is the worse nightmare of my life and I would not wish thus upon anybody out there.

Best of all is that these people bind you to a 2 year contract. Whether they can deliver the service or not, you just have to keep on paying and paying. Wow that is very nice of them. Let me lock you into a contract and suck as much out of you whether I can help you or not.
 
Mmm, I have a similar problem. Trying to setup Joomla for a buddy of mine and his Plesk Control Panel keeps booting me back to the Login page. It's a USA based server and the login page is secure. Strangely my own USA based server (different Company) has no problems, using Cpanel, but not over secure connection. Also FTP keeps on "freezing" after a couple of minutes. (On his account) Mine works fine. Just tried both accounts now and ditto. Sorry I can't be of more help, but it does suggest a server side, location or Secure site (bar the FTP) issue?
 
Thanks Led

Thanx a mil Led, please stay on this topic. At least now Vodacom can stop asking me bull questions like if I am connected with two connections simultaneously and keep on pretending that it is my fault and not theirs.

Tell your host that you are going to log into your control panel, work until it logs you out, then log in again, etc etc and while you do that, the must have a look at your access log and record your IP. They will note that while you are working your IP keeps on changing. That is why your are logged out all of the time and that is why you keep on loosing your connection while trying to FTP.

I am so fed-up for this situation I want to puke.
 
Vodacom

Perhaps we can try this, I will log into the Internet with my MTN GPRS. Then do all the work I have to do and at the end of the month send Vodacom the bill for the service which they could not render and for which I have to pay. How does that sound?

Does anybody here know if this would stand up in court??

Led, there is a known problem with FTP switching between port 20 and 21, so I agree with you that the FTP problem you saw is probably a different issue.

From your post it seems you see the logout problem only on a secure server but not on a non-secure server? Can you confirm?

Any idea what the difference would be between the secure and non-secure connections?

We push back one IP per connection, thus my 'bull question' if more than one connection (that would result in more than one IP) might be involved.

Mr 3G, you must please understand that some of us as users do not have the slightest clue how all of this work and I have no intention to find out how. I make my money from building web sites, trading forex and trading shares and I prefer to keep it that way. I have no intention of learning how all these connections and things work. They way I understand it, if I have one modem that connect to the Internet how can I have two connections? Is it possible to connect to the internet twice with the same modem?

All I see from this side is that I cannot upload the files that I have created. All of this is costing me Money. Get it, I AM LOOSING MONEY EACH DAY BECAUSE OF THIS. The fact that we keep on complaining about it and getting nowhere frustrates the hell out of me.

I am paying for a service but I cannot use it. In the end I have to use my MTN GPRS to upload the files which is costing me something like R2 per meg, because Vodacom cannot deliver. Every now and then I loose a trade because your service either disconnects me or I am connected but have no data transfer. The other day I was in a single stock futrue trade, I learned that the share would be turning south and I had to sell my futures immediately. I could not because it was oneof those (is connected but no transfer) happy days at Vodacom. SO I lost R1300 for the day, thank you Vodacom!:eek:

As we speak I am still trying to upload stuff to my server with no luck.
My server admin is also trying their best. Their answer this evening was:
i,
I managed to upload all files without any issues, check the private folder.
It worked flawlessly with the login details you provided, i used Total Commander (Windows Vista).
It's not a server-side issue.
If there's anything we can help you further with, please reply.
Regards,
Alex Vranceanu

I have tried everything. You guys even switched me to the Internet VPN.
It improved the situation a bit but still days like today happen. After the VPN thingy it happens less that I loose my connections or do not have transfer, but still some bad days it still happens, but it is less than in the past.
My connection is not like this all of the time. I work without problems for a day or two and then BAM, al off the sudden one day this happens. Normally it is the same symtoms. The moment I get logged out from a secure site I know that the next thing will be that my ftp will hang and not transfer data.

I even bought myself a Vodacom pay as you go just so that I can call you call centre (and wait 10 minutes for reply) because you keep on asking if I phoned 155. But each time I have to explain that I am not, and never intend to be a Vodacom client as far as my cellphone is concerned, and if I use my MTN phone to call your call center and wait ten minutes for a reply it would cost me another fortune.

By now you should have my number but if you do not have it, my 3G card's number is 0795156006 and my contact number is 0834315841

Most probably it the thing will work tomorrow, let's go on our knees and pray that we will get what we pay for tomorrow.
