Access a webserver on a computer that has a router from the internet.

Hi I am new to routers and wanted to get some information on how to access a webserver that is on a computer which is connected to a router. I am very confused about port forwarding. Basically lets say that the webserver is on a computer with the ip of 192.168.1.100. I want to know how to use the internet IP (either one that is auto or one that is fixed) to connect to the webserver outside of the local network from a computer on internet. I was able to do it before the router was installed. Can someone explain this to me or point me into the direction of something that is easy to understand? Thanks, Message Edited by wjriv on 03-26-2008 09:16 PM

Still having problems..   I have configured the router to forward ports 80 (web server) to my Linksys router address of 192.168.1.100 (which is the address for the computer that the web server is on).   I also tried DMZ to 192.168.1.100..
I use DynDns to direct my IP address...
I know it works, because I can access the router config from the Internet through port 8080...   But when I try to put in my DynDns or actual IP address (for example: 100.110.10.201)   I enter it as follows:    http://100.110.10.201:80
But I am not able to access the web server from out side of my network.
I have also made my computer with the web server keep the IP address static.
Are there any other things that need to be configured in the router or even in the firewall of the computer?
I have noticed that this has been a major issue in different forums, but I have not been successful with a solution.
My ISP is Bellsouth.net..   I am not sure if they could be blocking anything..
It actually works when I remove the router from the system and just connect it directly.. so that is telling me that there is something else that needs to be configured on the router.
Can anyone help me or direct me to the solution?
This is really frustrating....
Thanks..

I have a ipod that had photos synchronised to an old computer that has sinced crashed and the data can not be recovered. How do I recover the photos stored on the IPOD to my new computer?

You'll likely need the assistance of some sort of 3rd party software. Keep in mind that the photos on your iPod are only scaled down thumbnail versions of the originals. So even if you do manage to copy them backt to your PC, they will not be in their full original resolution.
Do a simple Google search for "copy photos from ipod" and you should get a number of hits that can assist you.

Not unless the developer/Apple offer it again in the App store. You can only get apps from the App store.

Does the iOS device connect to other networks? If yes that tends to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router

My computer has stopped printing from the internet, I used to be able to but not now?

I can no longer print from the internet, I can print my own documents, but not from internet. This has only just started to happen what can be the problem?
Your help would be appreciated.

What mechanism are you using to access the printer remotely? If it's supported directly by the printer, which printer? (It's fairly uncommon to have an openly-accessible printer on the Internet, so there's usually some security involved here; a VPN or other mechanism to protect the traffic, and some authentication. The ISP can also block some of this traffic, and your network firewall is also involved in permitting or denying access.)

How to authorise a computer that's not connected to the internet?

i use my the computer in my studio to watch dvd's all the time - who needs a tv when you've got a cinema display? the thing is, i recently purchased some tv episodes from itunes to watch on my studio computer - however, when i try to play them, i get that "this computer is not authorised to play blah blah bah" message. i also get this when i plug my ipod into itunes and try to play my itunes purchased tracks via this computer. when i try to sign in so as to authorise it, it tells me no network is detected.
well, thats because this particular isn't connected to the internet. it's old, it doesn't have wifi, and it's my work computer, so i dont want internet on it anyway - i'd never get anythong done!
so, with most programs requiring you to register/autorize your computer, there's always an option for "if this computer isn't connected to the internet" . however, i didn't see how to use this option for itunes.
which is odd, since every other company in creation has this option right there on the authorization screen.
for the record, i DO NOT WANT TO PUT THIS COMPUTER ON THE INTERNET. it's kind of old, and therefore delecate. so disentangling it from the various studio equipment it's attached to and moving it, along with the big cinema display, to the upstairs room where the ethernet cable is, will not only be a giant pain in the *$$, but also will quite possibly break something - like i said, it's old, it's bones are brittle and it has arthritis and it's happiest left right were it is - to move it is, i believe, to invite disaster.
but i'm confidant apple has provided a solution for this, seeing as all the other software companies i purchase from have managed to so, anyone know how to do this?

"No it is not reasonable. As stated by Jobs in his 'We hate DRM' letter, they are forced to keep the DRM as uncrackable as possible. So this stuff has to remain in an online state."
itunes seems to be bending over backwards on this. amazon.com doesn't seem to have this problem for one.
"you would find that nearly any sofwtare with some kind of offline registration scheme is easily cracked."
i dont spend that much time digging around for cracked software (i prefer to pay for it) but to the best of my knowledge the software i'm thinking of isn't easily available in cracked form. their registration/authorization process is vigorous, but still includes an offline option.
"Nope. Wrong. Notice how it only their music that has these online restrictions and that none of Apple's other software does this. The difference as explained above is clear. Apple has their hands tied on the matter for now."
i probably wouldn't be half so pi... annoyed if my macbook didn't just break down a week after the warrantee ran out. apple's free pass on their weaker points has expired as far as i'm concerned. i suppose there will continue to be disciples, but i'm about ready to sell all 5 of my apples and switch to the darkside.
anyone want a black ibook with a broken dvd drive and no warrantee? going cheap, yours for 30 pieces of silver.

Anyone know how to remove an old computer that doesn't exist from the iTunes wifi sync list?

I am trying to remove an old computer that I don't have anymore from that list. I tried the 'de-authorize all" but that didn't work.

About De-authorizing Computers (contributed by user John Galt)
You can de-authorize individual computers, but only by using those computers. The only other option is to "de-authorize all" from your iTunes account.
1. Open iTunes on a computer
2. From the Store menu, select "View my Account..."
3. Sign in with your Apple ID and password.
4. Under "Computer Authorizations" select "De-authorize All".
5. Authorize each computer you still have, as you may require.
You may only do this once per year.
After you "de-authorize all" your authorized computers, re-authorize each one as required.
If you have de-authorized all computers and need to do it again, but your year has not elapsed, then contact: Apple - Support - iTunes - Contact Us.
Also, see iTunes Store- About authorization and deauthorization.

Regarding joesilva's problem with the one computer that can't get on the internet.

this is joe, i left a lot of info off on the first discussion, sorry. there is nothing wrong with my airport, it just can't logon using the verizon jet pack.
i was having so much trouble with it that i suspected it was something that verizon had done by changing the connection requirements.
i even took the ibook to it one of there branchs and they tried to make work on there computers to no avail.
i previously had an another verizon modem, it is a MIFI12200 and when i turn it on iget a full signal on the power icon of airport.
the the ibook can't connect to aol because it has to be activated which i don't need. i only did this to test the airport extreme card.
how ever, with the mifi12200 i also get a VZ manager which allows me to see the signal level of both verizon modems.
there are 2 buttons,: NETWORKS & STATISTICS.
the network button shows both modemsas selections
the statistic button shows both modems and they both have a signal quality of 100.
the Verizon modem MIFI shows encriptrion as WPA Personal Channel 11 and signal quality as 100
the verizon jet pack modem shows encryption as unknown Channel 1 signal quality as 100
When i go to keychain to view the passwords, the MIFI asks for password and it allows me to open file to view.
for the jet pack it will not let me open file, say's iv'e entered a wrong password.
when i try diagnostics, im unable to chose WPA2 Personel. for airport informatiom it only shows 3 choices,( WEP Password) (WEP40/128-bit hex) (WEP40/128-bit asc11. very confusuing.
iv'e also copied the airport data ,TCP etc. nothing worked. thanks for the previous help.

Hi,
The executeQueryAsync method is “asynchronous, which means that the code will continue to be executed without waiting for the server to
respond”.
From the error message “The collection has not been initialized”, which suggests that the object in use hadn’t been initialized after the execution of the executeQueryAsync method.
I suggest you debug the code in browser to see which line of code will throw this error, then you can reorganize the logic of the code to avoid using the uninitialized object.

I can't remove a bookmark of a form that has been removed from the original database it was on.

Local county website removed a form students use and placed it in another location of its website. I had the form bookmarked in its old location. Now I can't remove the bookmark for the form at its old location. Also, I'm not sure if the old/new location has anything to do with my inability to remove or delete that bookmark.

Would you check the Bookmarks sidebar, and look for there in your groupings, and also do a search on it there. From the location bar use and internal search by not hitting "Enter" and include a space delimited asterisk ("*") to restrict to bookmarks.
The Bookmarks Menu (menu) often lags behind, especially when you have lots of changes.
I don't use the Bookmarks *menu* to look for bookmarks. I like the organization and faster scrolling of the bookmarks sidebar.
Restarting Firefox will probably fix the Bookmarks *menu*
If you want to play with it you can try these, but I don't make a lot of bookmark changes in a session that it would bother me that much.
* creating a bookmarks backup and then restore it via Bookmarks Library List ("Ctrl+Shift+B") > Import and Backup > Backup --- then restore that backup.

Is it possible to restore backup that has been deleted from the repository?

Hi,
with Rman 9i I do a full database backup including the current controlfile each night (with the catalog option). If the backup has been successful all backups older than 3 days are deleted (because of a lack of disk space).
Now I have to restore a backup older than 3 days which can be written back to disk from tape.
On disk there is a backup still available which is 2 days younger than the one I have to restore. That means in its controlfile the backup to be restored doesn't have the status DELETED yet.
Can I restore this controlfile first, then resync my catalog and restore the old backup after the entry is back to the catalog ?
How do I specify which controlfile and which backupset should be restored ?

Hi ebrian,
thank you for your quick answer.
Just to be sure that I understand you right:
I startup the database in nomount mode.
Then I restore the controlfile from the backup which is 2 days younger than the one I have to restore because this controlfile contains the desired backup record with status "not deleted". Is that right ?
Each of my backup consists of 3 backup pieces. How can I find out which of the pieces contains the controlfile ? Or can I try one after the other until it works ?
After the controlfile is restored successfully I use the following commands to restore and recover the database:
rman target=sys/<syspw>@target_db
run {
alter database mount;
allocate channel c1 type disk;
set until time '<point of time a little bit prior to the point of time of the backup to be restored>';
restore database;
recover database;
release channel c1;
open database resetlogs;
exit;
Because of the "resetlogs" I take a full backup of the database afterwards.
For the future I intend to change the process of deleting backups as described below:
* delete them from disk with operating system command not with the rman delete command
* configure retention policy to recovery window of n days (n = number of days backups are preserved on tape)
* start rman script each night: \\ allocate channel for maintenance device type disk; \\ delete obsolete; \\ release channel;
Is it possible to restore each backup from tape if required with the procedure described ?
One last question concerning the recovery:
instead of the "set until time " before using the "restore database" command is it possible to specify a concrete backup to be restored (e.g. specifying the exact time it is taken or the backup piece numbers) ?
Thanks in advance.

How do I remove a bookmark that has a star from the awesome bar?

isn't there some way to permanently remove an entry from the awesome bar? This is also a very annoying problem. If a site is a bookmark then sure it can be deleted from the drop down list, but the next time you go to the awesome bar it is there again. I want to be able to permanently remove a bookmark from the awesome bar. Period. How the heck can I type in a site that is a bookmark that I do not want to appear in my drop down list in the awesome bar?

You need to understand my question.
As a user, I do not want to delete or eliminate all bookmarked sites.
On occasion, however, I only want to delete only a single or a few websites from their bookmarked status and stop them from appearing on the drop down list in the location bar.
So, for example, if I see in my drop down list:
Apples.com
Ardvarks.com
Airplanes.com
and all are bookmarked sites
and I just want to stop Ardvarks.com from appearing in my awesome bars' drop down list every time I enter the letter "A"
then that's what I want to do.
I do not want to stop Apples.com or Airplanes.com from appearing in the drop down list.
There must be a way to permanently stop Ardvarks.com from appearing everytime I look at the awesome bars' drop down list.

HT1369 I am being told i-tunes has detected a problem with your audi configuration. Audio/Video playback may not operate properly". I HAVE CHECKED THAT MY INTEGRATED AMPLIFIER IS WORKING WITH THE LEAD THAT HAS ALWAYS WORKED FROM THE COMPUTER.What should

I am not having any trouble with my i-pod which I can continue to connect to the computer to update. However when I get into the listen to the music on the computer I am unable to hear anything. This is also true for Spotify, and my own cd's inserted in the computer and i-player. I have connected an old Sony Discman to my amplifier and it works perfectly, so I know that the problem is not with the amplifier or the lead so it must be the computer audio.
My computer is a COMPAQ CQ 1140UK SLIMLINE DESKTOP PC.
I need to stress that I am a 65 year old non tech user. I use my computer a lot but have no idea how it works!! .
I believe that in my efforts to resolve this issue myself by going into the control panel .....I may have caused even mor problems.
At first, today, I could see that the track was playing, CURSOR MOVING ACROSS THE TRACK LINE, but I was getting no sound....now the tracks don't even seem to be playing at all!!
I remember, afew days ago seeing something flash up on Spotify about how it was going to do something with my i-tunes but it stated that it was nothing to worry about! So I didn't, until today!!
I only used Spotify to locate a track before I purchased it through i-tunes.
If anybody could advise me of what I could do to resolve this problem then I'd be most grateful.
This is my first time on this Apple Support Community so I hope that I am right in thinking that any response will arrive in my e-mail.
Thanks again

HOW DO I TRANSFER MUSIC FROM MY IPOD TO A 2ND COMPUTER THAT HAS LOST MOST OF THE MUSIC IN ITUNES WITHOUT LOOSING THE MUSIC WHICH IS NOW ON MY IPOD

MY OLD COMPUTER HAS THE CORRECT MUSIC INSTALLED IN ITUNES.
I HAVE NOW INSTALLED THE CORRECT MUSIC ON MY IPOD-NANO
I HAVE A 2ND COMPUTER WITH AN INCORRECT MUSIC LIST IN ITUNES.
I NEED TO COPY THE CORRECT MUSIC TO COMPUTER 2 FROM MY IPOD WITHOUT LOOSING WHAT IS ON THE IPOD.
THANK YOU

Typing in all caps indicates shouting is considered rude and is difficult to read. Many simply do not read such posts.
The music sync is one way - computer to ipod. The exception is itunes purchases. File>Transfer Purchases
You need to copy everything from one computer to the other.
