Internet Connection Sharing / Hanging at 211-Features:

#1 Post by cyberjock045 » 2008-10-11 05:44

I did a search on "Internet Connection Sharing" an didn't come up with much help on this issue. I have no problem connecting to my Filzilla FTP Server when I am "directly" connected to the internet. Here at home, I have one Vista computer that is "directly" connected to the internet and is sharing the internet with the rest of my computers using "Internet Connection Sharing". The Vista computer that is "directly" connected has no problems connecting to the FTP Server, but none of the other computers will. I have disabled Windows Firewall on all computers and have no other firewalls connected. My Filezilla FTP Server is also running on a computer that is "directly" connected to the internet and the Windows Firewall is off on it as well. At this point I am not sure if the issue is Client side or Server side so I will list the log on both. I thank you for any help you can give wit this issue. If this is an issue that has been resolved in a prior post, I apologize for not being able to find it.

Ask your ISP for a second IP address and then get a simple switch. Then both your computers can access the internet independently.

Thank you for the suggestion, but that does not resolve this issue. I am not willing to pay for an extra fee every month, just to be able to access the FTP from other computers here, and it would be really expensive. I have 7 computers here and last I looked, my ISP charges an extra $10 per computer that you want to connect. So an extra $60/month just to be able to access the FTP? Not worth it. Additionally, I am actually trying to learn more about FTP and HTTP servers and how the protocols work... and this would just be defeating the purpose.


Thanks,
Joe

Maybe I do not understand the problem exactly, but why you are not using the LAN ip address?

I'll explain in more detail. I should have done a better job of explaining the issue, I apologize.

I have a computer at work that is running Filezilla FTP Server and it is directly connected to the internet (no routers or firewalls). I call this my "FTP Server at Work".

I have several computers at home. Only one of them is directly connected to the internet and is running Windows Internet Connection Sharing (no routers or firewalls). I will call this my "Internet Sharing Computer". All of the rest of my computers at home are on a LAN with the "Internet Sharing Computer" and they able to connect to the internet though the "Internet Sharing Computer".

The "Internet Sharing Computer" can connect my "FTP Server at Work" with no problems (using Filezilla FTP Client). But none of the other computers at home can connect to my "FTP Server at Work".

So, If I am on a computer that is directly connected to the internet I have no problems connecting to the "FTP Server at Work". If I am on a computer that is not directly connected to the internet, and it is getting it's internet connection though a computer using Windows Internet Connection Sharing, I can not connect to the "FTP Server at Work".

I have included a network map of what I'm talking about below.

I hope this makes easier to understand what issue I am having. Thanks for any help you can give.

It is a well known fact, that the Application Layer Gateway Service (ALG.exe) of Windows actively sabotages FTP connections. You'd need a proper, dedicated NAT router that does not sabotage FTP connections with properly configured port forwardings.

Most likely there's just something in the FEAT response which your firewall/router does not understand so that it closes the connection. Nonetheless the output of the FEAT command of FileZilla Server is standards compliant, so not a problem in FZS.

Ok. it it is the firewall, please give me a clue what to look for in the firewall settings. I also DMZ'ed the server and that changed nothing.

Thanks

Here is an update to the orginal problem reported by "cyberjock045" I have been able to duplicate it and it is only if you are using VISTA ics. Also this only occurs when connecting to a filezilla server as I am able to connect to servers that are hosted by "ProFTPD 1.3.2e Server"

Even if I get the wizzard to pass (see below) the system still will not connect to filezilla server windows 2000 server sp4. I have two servers and I can't get to either. I also tested smartFTP client and it shows the same results. Remember, it all works find on the main vista computer, the one that is sharing the connection.

Here are also the results of the wizzard

you must first select "get external address from url " or it will fail

SOLVED?

I was able to get it to work by changing the public port on the router from 20 to port 8891 and 21 to port 8892, JUST the public port on the router so that the internal net is not affected.

All work fine ! I guess that the problem is in the ICS can't deal with the routing of the ports 20 and 21

long live work arounds!

I still think that FZ client/server is doing something funny as other clients/server ftp solutions work going through ICS, see post dated 2010-01-07 00:12.

Probably it stops because of the UTF8.
