I have two linux machines(A and B) and a remote service. The service is listening on port 16000. The outgoing connection from machine A on port 16000 is blocked by a firewall, but on B it is not. I need to access the service from the A. So it will probably need to be routed(correct term?) through the B. I cannot modify the program which is accessing the service(so it will always try on port 16000).
I know there are a lot of tutorials on similar topics, but I don't know which one should I follow, because there are apparently many possibilities. I have full access to both machines. What is the best way to accomplish that? What should I execute on machine A and on machine B?
I am trying to open up port 32400 on my 881w Cisco router but I have not had any success I need to configure manual port-forward to enable my Plex Media server.
I have two machines in my network (A and B), where A is the one directly accessed from outside when calling my IP address and B is a very powerful one which should serve for very intensive tasks.
I would like to forward a certain port, e.g. 9090, from A to B, so any request sent to A on port 9090 is directly forwarded to B.How can that be achieved?
I'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level. I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other. I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it. This seemed to allow devices connected to the switch ports to talk to the built-in router ports. I thought this was all making sense until i applied an access-list to the router port. It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere. I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port. However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully.
It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.
(Setup routing and iptables for new VPN connection to redirect **only** ports 80 and 443) Only my goal is a bit different. I am running a headless gui-less install of Ubuntu Server 12.04 that is being used for a variety of different purposes... I would like all traffic to travel un-prohibited through my ISP except for my transmission traffic. I have a VPN i subscribe to that allows me access for which I only want to direct a single port's traffic to. I am currently using a modified version of the code from the above link. My current code is below:
how to: port forwarding to 2 different destinations based on incoming WAN port
The default HTTP service works fine: TCP80/80-> 192.168.0.55
I have a couple of IP security camera's I'd like to be able to access remotely that also listen on port 80. I tried TCP & UDP 8009/8009-> 192.168.0.9 without any luck. Not sure how to handle the port redirects on the RV042G? Seems simple and was on the Symantec, could be user training :-)
I was able to do port redirect with the Symantec Firewall I'm replacing.
Region : UnitedKingdom Model : TD-W8970 Hardware Version : V1 Firmware Version : 0.6.0 0.11 v000c.0 Build 121203 Rel.46289n ISP : Virgin Media
Is there any way of forwarding an external port to a different internal port on the TD-8970 ?I saw a question posed on an Australian forum implying that it might be provided in a later firmware release.Our TD- 8970 has replaced a previous NetGear WAG 320N which had this facility, and is useful to provide access to multiple machines without having to modify each individually to use a different port.
I can SSH from the internet to my ASA on default port 22, directly to my public IP. I can SSH from the internet to my Cisco 1841 on port 2001. I can not however, SSH to my Cat 2960. From what i can tell, on the Cat2960 i can't change the default port 22 for SSH to different port, just like i did on the Cisco 1841. I looked to see if I can change the default port for SSH on he ASA, it does not look like this is an option.
The bottom line is that i want to be able to SSH to all three devices from the internet. I only have one public IP. As of now, what i can do is only SSH to the ASA on default port 22 directly to the public IP and Cisco 1841 on port 2001. It appears that changing the default SSH port on Cat 2960 is not an option. It also appears that I can't change the default SSH port on the ASA, if i could, i would and then i should be able to SSH to the Cat 2960 on port 22. No matter what i did on the ASA, it always listens on port 22 for SSH connections.
show asp table socket TCP 001f549f <<pub IP>>:22 0.0.0.0:* LISTEN
how do i make it listen on different port?
Here is relevent config for SSH for cisco 1841 (port forwarding)
Is it possible to create a service which will forward public port 9010 to an internal IP address with port 23 ?
First of all, I do not like to open the public Telnet port to the inside so I would use another public port and second my ISP does not allow some public ports beneath port 80
I am having an issue opening a port (4040) on the 655 for my Fedora-based subsonic server. Inside the LAN, I can see the device from other peer machines, so I am confident the port is open and listening. However, I can't seem to get to the machine-port from outside/internet.
I have tried Virtual Server and Port Forwarding with single port. The server has a stactic IP which I've included in the DHCP range and outside the range. I have a DSL connection (AT&T), modem only. I have updated firmware. I have exhausted the Subsonic community's knowledge, everything points to the router, but all the settings seem correct. What am I missing? Is if possible there is a defect in the router? (don't laugh). Is there a way to trace a request to that port to see where it is hanging?
I have always used netgear routers in the past. After a series of issues regarding configurations not working correctly I invested in what appeared to be a semi pro router, the cisco linksys e4200.
I have a centralized server which I use to access a mass of different services such as mail, dns, VPN, FTP, Kerberos, http and many more. While I am not a massive networking ****, this server setup is like my garage project. To access these services externally to my LAN as far as I understand I would need to configure port forwarding for each service to my server. Unfortunately the control panel for the linksys E4200 only offers about 15 custom port fields for forwarding, and some documentation I have read shows that with it's basic install my server could be using up to 60 ports at once.
Is this router just not suitable for this sort of network. If so I will be very disappointed because I have spent a quarter of the price on netgear routers with more control than this.
I've set up port forwarding from an external port (9000) to an internal port (80) on our SRP541W, and for some reason, it's not working externally. If I access the public address from within the internal network, it works properly.
I want to create a Counter Strike Server and need to open some ports for that.The Problem: I cannot seem to open the ports for gaming.The Modem Setup: My Firewall is disabled.My guess is that, this is the area with the problem. I guess my modem is not forwarding onwards.The Problem: I tried checking my ports with websites like URL etc.It cannot access my port.
I have a DSL-524B from D-Link. My problem is, whenever I Port Forward port 80 to my comp's IP to host a web server, all the other computers connected to the router are unable to access the Internet. So, I set up no-ip to use port 8080, but, this exposes my ip and even when masking, if you look at the HTML code, you get the ip.I need to know how to open up port 80 without restricting Internet access to only my comp, or any other work around.
I was at a friend's office today trying to get the IP cameras working but forwarding the ports seems not to work with his current modem from ATT (a Westwell F90 or something). Would the workaround for this be purchasing a third party modem instead that supports port forwarding and stop leasing the Westwell F90 from ATT?
edit: the modem is hooked up to a DI-524 from D-Link and i already forwarded different ports to see if it was specifically port 80, 1024 etc
I am trying to track down a device that's blocking a certain port I know there are programs out there than will do a trace-route that's on TCP but is there any programs that allow you to specify a port?
[code]... How do i setup port forwarding in server 2008?? I have heard numerous ways of doing this through windows firewall, NAT and setting up static routes. Not of which i can get working.
I finally got my Cisco Pix 501 working on my network and everything is working great! However, I do host game servers on occasion and I have a 24/7 FTP server up and as of now, I can't connect to it because the PIX is blocking the ports!I have zero experience with Cisco, so I need step-by-step instructions on what commands to enter to get this thing working!
I am very confused now. I got my 5505 for home (basic) and loaded up 8.4(1) fresh. From the inside interface I can reach the internet no problem but I am having issues trying to get my port forwarding to work with torrent. inside host is 10.100.130.5 port is 26883, I have been trying to configure this forever.
I am trying to make a server in the game Halo combat evolved for the PC, but i need to forward 3 ports, ports: 80, 2302, and 2303, i did them all, but it still says they are all still closed, when I scan them or they say, its times out.I have a D-Link router.
I need to set a static IP for port forwarding so my clients can connect directly to my server. I kept losing people because my IP address would change every week. I use version MI424WR router and know my Mac address but do not know which IP address I should set it to.
I have a computer connected through wifi to the internet.I then turn on the computer into ICS mode and connect that to my PS3/Xbox.I'm trying to get an OPEN NAT type but just can't seem to get it working.I've read a few different pages and have tried some things but it's never worked.I've heard of bridging connections and the sort but I'm not familiar with it. I just want to get an OPEN NAT on my PS3/Xbox.

I have Infinity so don't know if that's an issue in my situation. I know I'm being "throttled" by BT when doing P2P downloads so limit this to off peak periods.I have made the recommended tweaks to Utorrent to speed things up and finished off today by port forwarding. I tried to follow the tut I was using to the letter but the download became even slower!! You have to enter the port number in the Hub settings but I wasn't sure whether it was a single number xyz or a range 0-xyz or even xyz-xyz. I really hope I'm making sense.I also wasn't sure whether it's TCP or one of the other options I should have selected. I'm currently on Infinity getting 37.4 Mbps download and 1.7 Mbps upload.
We have the above router for a small business and I want to configure VPN to port forward to the server so it can handle the VPN traffic through Routing and Remote Access.I have configured port forwarding on SMTP, RWW and other protocols successfully but VPN will not work.Within the built in web interface on the Cisco it advised that if I want to configure VPN I need to use Cisco Config Pro. I have had a look through this software but it looked to only support the router as the VPN gateway rather than port forwarding to a server.
I have recently purchased a Cisco 871 router. In the GUI from the installed software, I have been able to configure which ports are forwarded to a specified IP address within my local area network. This seems to output a configuration line like this:
However, I can only do this one port at a time. Is there a function or command that I can use to specify a range of ports? For example, I would like to forward tcp ports 1000-2300 to the IP address 192.168.1.123
command for port forwarding to a few applications (inside hosts) when you only have one Static IP (Public) which is used for many to one NAT (Overloading)?This is the config for the many to one NAT.access-list 1 permit 172.16.0.0 0.0.255.255 ip nat inside source list 1 interface Dialer1 overload What command is necessary to forward ports to certain applications?
I am trying to setup Internet based CCTV system on a router that has a VPN network in place. Am i able to forward the Media and Web Ports to the router without interfering with the current VPN settings.
Before I get into asking questions about the routers, firewall, and static IP though I want to knock out the most base problem. I plugged a computer directly into my cable modem, disabled the windows firewall, tried canyouseeme.org, and couldn't connect to any ports anywhere in the spectrum. I would assume that being plugged directly into the modem that all ports should be wide open. The port I was originally trying to open was 8093. I called my cable provider and the tech told me that I'm not allowed to have port forwarding in a range as high as 8093 without a business account. I asked the tech what range I could use and he said he didn't know. I did some searching on the net and found that on a typical home cable connection I'm allowed ports 1 through 1024, so I tried numbers all over that spectrum on canyouseeme.org and got no response from any of them. Again, this was while plugged directly into my cable modem with an ethernet cable and my windows firewall disabled. From what I know this has to be wrong in some way, as to use the internet at all I have to have ports available. The only possibility I can think of is that maybe canyouseeme.org is flawed in some way. So the first in a long series of questions to come is why am I unable to find any open ports while plugged directly into my cable modem with my windows firewall disabled?
I have tried everything possible with this modem and router. I cant figure it out. I tried the router in bridge mode, tried opening the ports up on both of them.
