Port Fowarding problems

OK, I have a WRV200 wireless router. My problem is with port fowarding. It works fine off of a single ip address. For example, if I want to forward a port to 192.168.16.16 it wotks no problem but whatever a try to forward to another ip it doen't work. For emaple we added a new server and want to forward port 5901 on it but it doesn't get forwarded. If i istall the application to the other server and forward 5902 to that servers ip 192.168.16.16 it works. Anybody have similar problems. I have 3 of these out at client locations and all 3 act the same. I just never noticed it because I only had to forward any ports to a single internal ip.

Did you try to update to the latest firmware?

WRT54G port fowarding problem

Hi, I've had my router for a few years and have opened ports alot of times. I know how to do this and everytime I've done it in the past it's worked fine. Right now I'm trying to open port 80-81 and whenever i click "save changes" I get this error:
This web page is not available.
The web page at null might be temporarily down or it may have moved permanently to a new web address.
Below is the original error message
Error 320 (net::ERR_INVALID_RESPONSE): Unknown error.
I can't figure out what's wrong and my friend who has a different linksys modle says he's having the same problem.

It is a browser issue. Please try to use a different browser.

It would help if you stated what port your talking about I am guessing your talking about port 80 and webserving.
In order to use a domain name to connect internally to your webserver or any other type of server your router needs to supporit's not easy being greent loopback.
If your router does not support lookback you need to edit your hosts file.
If your trying to connect to the server if it is running on your mac you need to add the following line to your hosts file. you can can use pico to do that.
sudo pico /etc/hosts
then add the line
127.0.0.1 your.site.com
or if the server is on another ip on your lan use its local ip
192.168.0.5 your.site.com

Port fowarding not working and Max Payne 3

I have had a proble with this game badly lagging and some things not being applied to my account while playing etc etc etc
Now the ports that I've already opened ( or seemingly not ) are :-
UDP 6672
UDP 27900
UDP 27901
443
I have put the Hub 3 ( 3A ) into DMZ, and when I go to an online port checking facility no matter which one it tells me that eaach of the ports are closed, and I'm still lagging in game etc
I'm not new to computers, just not done a lot of connection problems.I did the port forwarding via a BT tech rep over the phone, so there shouldn't be any problems with how it's been setup ( e.g me not putting in something should have been taken out of the equation ).
I've seen a few posts about the HH3a not doing as it should.So 2 questions here, can I ask/demand a HH3B, and is there the same problems with this as with the HH3A ?
If you have any other questions for me, be free to ask, but I might ask how to do some things
Andy

After 4 telephone conversations , it appears that either there is something wrong with the HH3 Type A , and port forwarding isn't happening , or the HH3 doesn't allow me to see if the port forwards are concerned, which isn't very helpful either way.
Added to which BT are unable to send me out a HH3 Type B because " they are undergoing testing at the moment, because there is a problem with them " , quote , unquote.It has taken these 4 phone calls to find this out, which could've been explained the first time, instead of just fobbing me off, saying the port fowards are done, when clearly as far as online open port checkers are concerned, their not.
So, there isn't any way I can go back to the game developers technical help , until this problem is sorted.
I've put a post on another thread asking which router would be best for me to purchase, as this seems my only course of action, with BT just washing their hands of the situation, saying that although port forwarding is part of the HH3, it doesn't mean to say that it works, and they don't support it !
Many thanks for any replies.

Creating a Server WITHOUT port fowarding

How do I make it so that a person can download the server.jar file, run it, and have people connect to it (socket 11114) without having to configure their router to foward that port. I know its possible because in professional games, people can connect to each other and the user doesnt have to use port fowarding.
Thanks

Normally a client doesn't need to forward ports to connect to a server at all. A router usually prevents an arbitrary connection to a computer it's routing, since it may be routing many computers and the intended one may be impossible to identify unless pre-configured with the router. Connecting from the routed computer does not have this problem, so long as the server has its ports ready, except for the rare case where the router doubles as an anti-trojan firewall, in which case it needs to be configured accordingly, but that's really the client's problem(and fault, for enabling such a feature on the router in the first place, or actually picking out the extra-rare router that has such a feature on by default).
This simply requires that the client connects to the server, and never vice versa. This is okay for a connection-based protocol, like TCP.
For a datagram protocol like UDP, most modern routers tend to "remember" where routed computers sent a packet to, and use it to figure out where packets sent back should go, so as long as the client sends the first packet, and so long as the server sends replies within a certain timelimit(usually 60 seconds), it should work without any special port forwarding.
The few users using a router without that support would either have to configure their router, or use TCP only.

How to configure my AEBS to port fowarding?

The problem is that i cannot give or receive any webcam from my friend on aMsn or Yahoo Messenger. I know that i need to give a static IP to my computer and do port fowarding but i dont know how.
We have two iMac here, that are connected to internet via my AEBS. Secondly, I use a airport Express to stream music in my receiver and to connect my blu-ray my disc player and my Wii to internet.
So how arranged that without creating problem with my whole network?
Please, I would appreciated a clear method like 1- go to,... 2- click on,...
Thanks

WRT54GSV4 port foward for bittorrent?

hi, i have a WRT54GSV4 but am currently having problems fowarding ports in my router. even if i port fowarded the ports in "gaming and applications", it says closed on the utorrent reader. i dont quite understand about static ip thing. on the main page it says "automatically configuration DHCP" any help would be greatly appreciated
Message Edited by KamikazeD on 12-16-2007 06:29 PM

For a checklist see here.
Otherwise, please post the exact settings you use on the router for port forwarding, triggering and DMZ at the moment. Also check the status page on the router and make sure the router has a public IP address and not an address like 192.168.*.* or similiar (see the "Make sure the router has a direct connection to the internet" in the checklist above).

Can't run form from Form Builder 10g - Port configuration problem?

Hi,
I have installed the Database (10.2.0.1.0) and the Developer Suite (10.1.2.0.2) on two Linux machines (Red Hat Enterprise Linux ES 4 Basic).
If I enter the frmservlet-URL manually everything seems to be fine.
In one case I enter http://127.0.0.1:8890/forms/frmservlet, in the other http://127.0.0.1:8889/forms/frmservlet; in BOTH cases I get eventually a dark square and the status bar says "Applet oracle.forms.engine.Main started".
HOWEVER, if I create a simple form with Form Builder and click on the Button with the green traffic light ("Run Form"), the form runs only on the machine where frmservlet listens on port 8890.
On the other machine (frmservlet configured to listen on port 8889) Firefox pops up, the URL "http://127.0.0.1:32979/6dOrpwghCqnp8PhMT7KVT533m3IaArqFbPqPBOztZXWYSsNy" gets called, and nothing else happens. The screen displays the string "ORACLE FORMS." and the status bar says "Waiting for 127.0.0.1...", and it stays like this forever.
I assume this is a port configuration problem, but I don't have a clue where to start.
Any suggestions how I should proceed are greatly appreciated.
Thank you very much in advance!

Hi Frank,
Thank you for your reply.
I doublechecked my configuration.
In the dialog Edit --> Preferences --> Runtime the Application Server URL is set to "127.0.0.1:8889/forms/frmservlet".
However, when I attempt to run the form, the URL "http://127.0.0.1:33140/W2dwbV9eXS2fPkuKlxNhCxFWdEihwDviat2uV7ycrSotqwDN" gets called.
The screen displays the string "ORACLE FORMS." and the status bar says "Waiting for 127.0.0.1...", and that's it.
I wonder how the port number 33140 got selected. Interestingly, this time it is a different number; last time it was port 32979. In fact, the port number seems to change each time; I tried again and now it is 33189.
I will now try to set the port number for the frmservlet to 8890.
I choose Edit --> Preferences --> Runtime and set the application server URL to "127.0.0.1:8890/forms/frmservlet".
I stop the container, open /home/oracle/OraHome_1/j2ee/DevSuite/config/default-web-site.xml and change the port number to 8890:
<?xml version="1.0" standalone='yes'?>
<!DOCTYPE web-site PUBLIC "Oracle Application Server 10g XML Web-site" "http://xmlns.oracle.com/ias/dtds/web-site.dtd">



<web-site port="8890" protocol="http"
display-name="Oracle Developer Suite 10g instance of Oracle Containers for J2EE Web Site">

     
     
     <default-web-app application="default" name="defaultWebApp" root="/j2ee" />

<web-app application="forms" name="formsweb" root="/forms" />


<web-app application ="reports" name="web" root="/reports" />
<web-app application = "reports" name="demo" root="/repdemo" />
     
     <access-log path="../log/default-web-access.log" />
</web-site>
I restart the container, start Form Builder, connect to the database, and open my test form.
When attempting to run the form, the URL "http://127.0.0.1:33437/Pl0n3ky9vmU5z37A7ScBnQhsGwq3jwuzJpgTAKWPMOYIzT8K" gets called (again a new port number, apparently picked radomly within a certain range) and nothing happens: "Waiting for 127.0.0.1...".
However, when I enter the URL http://127.0.0.1:8890/forms/frmservlet I do (eventually, after confirming that I trust the certificate etc.) get a darc rectangle and the status message "Applet oracle.forms.engine.Main started", which tells me that my setup can't be that far off target.

Port Mapping Problem with AEX

I have a new Airport Extreme and a problem that did not exist with the Airport. I connect a Toshiba network camera to an Airport Express, set as a WDS remote, with the netcam connected to the wired ethernet port of the Express. I can see the netcam, which also functions as a web server, on the internal 10.x.x.x address, and have reserved a discrete 10.x.x.x address via the MAC/DHCP reservation function of the Extreme. Just like the older Airport which did this without a hiccup, I should be able to map a port (e.g. 1200) on the public IP to port 80 of the internal 10.x.x.x address, then access the netcam on the internal network from any browser (http://67.x.x.x:1200). My cable modem is just that: no router involved other than the Airport Extreme. I'm using the latest Extreme and Express firmware, and am either missing something with the new Leopard firewall, overlooking something else, or dealing with a product flaw. Any help is appreciated and Happy Holidays.

I have forwarded the port (have tried several different ports actually) in what I think it the correct way: using the Airport Utility, connected to the Airport Extreme, and, under advanced options, selected port mapping, entered the public TCP port of 1200, then the private 10.x.x.x IP address of the netcam (which I can access from the internal network with no problem), coupled with the private TCP port of 80. I then attempt to access the netcam from the Internet by entering http://my cable modem IP address:1200 (or another port to which I've attempted to map). This method worked for two years with the Airport, but, with the Extreme and Leopard (simultaneous transition), I'm stumped. After reading other about other port mapping problems, I reserved an IP address for the netcam based on its MAC with no positive results. I also set the firewall through the Security icon in System Preferences to allow all incoming connections. Thanks for taking the time to respond.

How to Port Foward Xbox One?

I don't know how to port foward the Xbox One to make the NAT type Open with my AT&T Unite Express device. I see the port fowarding option in the device's website, but don't know how to do it. Please help!

I'm having the same issue, has anybody managed to resolve this?

Port Fowarding Limitations

I do apologize if this has already been addressed, i did a search and did not find anything pertaining to exactly what i am looking to answer.
I currently own the Airport extreme. And my only negative comment about it is "Why was it not designed to use port fowarding ranges..?" "or why was it not designed to handle more port fowarding(limit is 25-30 i think?)"
I am curious if the new airport extremem addresses these issues or if it runs on the same principle as the older model. Thank you.

Echleon, Welcome to the discussion area!
In the AirPort Extreme (802.11n) discussion area, there have been discussions about this. You can enter ranges of ports as in 25-30.

How to make single port fowarding for camera by using airport extreme ???

hi
I have airport extreme model no A1143 (apple)
when I was using linksys ,I have camera
I reserve IP local for camera and then by aplication single port foward I put IP local for camera so I would get for the picture or video
Is any body can help by using apple airport extreme model no A1143
where should I put the IP local for the camera ?which application
thanks
Message was edited by: charlie368

charlie368, Welcome to the discussion area!
Using AirPort Utility you can configure the AirPort Extreme base station (AEBS) to forward the port(s) to the camera. However the camera will need to be assigned a local IP address. The default local IP addresses are in the 10.0.1.x range.
To get to the camera from the internet, you would use the IP address provided by your ISP. This is the one used by the WAN side of the AEBS.

Port Foward: BT Homehub 5 Minecraft

Right, hello!
I have an issue that hasn't been resolved for 3 Homehubs now. I'd like to set-up a Minecraft server, with the port of 25565. I've tried this on 2 BT Homehub 3's, one which was apparently faulty and the second was apparently fine. It didn't work, still. I finally got the new Homehub 5 and once again: the port remains unopened! How can this be? I've tried to see if this was an issue with my firewalls, so i disabled them on both the hub and my PC and the port remains unopened!
Please, can someone tell me why this is happening? I find it extremely annoying that I purchased this PC with the express intent to set up a minecraft server yet every time I try I get no results.
I've used sites such as canyouseeme.org to tell if my port is open, as well as trying to join the server myself, but it always responds with "the port cannot be found" or something like that. Always closed.
If you have an answer, please consider the fact that I have been trying this for a LOT of time, and as kindly as possible, avoid suggesting obvious or basic advice as I have searched far and wide for this stuff!
Thank you,
-Tom

Photosmart printer D110A CN732A How do I solve a port match problem?

operating system: windows 7
Error message: port match
Any changes made to your system before the issue: No
When I go to print something It tells me it's printing, but then never does. The explanation is always just the simple "error". I've used troubleshoot, re-started everything and ran the diagnostic test which told me it was a port match problem. My printer will still copy.

Hi there,
Try downloading and running the print and scan doctor located here:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03275041&cc=us&dlc=en&lc=en
It can fix a lot on its own and if not give a better idea of what is going on.
Best of Luck!
