Cisco Switching/Routing :: 876 - Port Forwarding Used From Internet
Nov 28, 2011
I have an problem with my new Cisco 876 Router. I configured port forwarding to access internal network devices from the internet . This works good from external but with my old Fritz box I was able to connect to this internal devices from the same internal network with the dyndns address.
So here is a short review for this:
DYNDNS Address port tcp 80 - > 192.168.0.80 tcp port 80
from ex tern it works but with source address example 192.168.0.20 to destination DYNDNS address tcp 80 (maps to 192.168.0.80 tcp 80 ) it doesn't work. Is there any trick in the config of cisco to let this scenario work?
I have my Cisco 881 router up and running, routing all traffic on my small network. I am wanting to utilize port forwarding to enable FTP (forward port 21). All docs I have found say you need to be running Configuration Professional (not Express) to do this.
I need to configure the port forwarding on Cisco 887 to forward port 22 on Public IP to a LAN IP port 2200. I don't know anything on Cisco router at all, beside telnet to the cisco and quit . Any step by step command.
I have a Cisco 881 router in my office and I would like to do port forward for port 5060, and 10000 - 20000 to my PABX(192.168.1.61). After I did some research from internet, understand that we need to NAT by using following command to do port forward for port 5060. ip nat inside source static udp 192.168.1.61 5060 XXX.XXX.XXX.XXX(WAN IP) 5060 extendable However, now I'm facing an issue to perform port forward for a huge range of ports like 10000 to 20000.
I want to SSH into a Cisco 1841 router and depending on the suffix added to the SSH (i.e ssh myrouter.myroute.com 2002), would like it to forward this request to a terminal server.Can this be done? If so, how does one accomplish this? I have done something similar with RDP but I was not sure about SSH.

I've a 877 Router and I would to:NAT al LAN Client with x.y.w.57Configure some ports ( i.e. 80 and 443) to be forewarded from x.y.w.57 to one LAN Server ( i.e. 192.168.0.1)Configure some ports ( i.e. 443) to be forewarded from x.y.w.58 to another LAN Server ( i.e. 192.168.0.2)
I feel like this has probably been asked a thousand times over, but it doesn't seem to work for me. TCP works fine. I can't find any definitive answers, I'm still a novice with the IOS.
The purpose behind opening the ranges of UDP ports to the interface and forwarding is because the people in question want to run a VOIP phone from their home, but they have a home grade Internet connection, so therefore no static IP. Also, they're not going to pay for a router to create a S2S VPN.
Also, from one of the remote sites for which there is a VPN ( the 192.168.6.X/24 site), the audio is only one way. The phone guy says "i need to open ports both way through the VPN), but I feel like that's already been done??
For my other site ( 192.168.15.0/24 ) I have an IPSEC over GRE tunnel going, I don't know about the status of the voice phone there..or if its even made it there
Here's my config...i'm redacting things like public IP's, VPN keys, and the like

I have a non-cisco router with a public WAN address. This is conencted to a 3750 switch internally. The switch is the default gateway for all VLANs, and the gateway router has static routes back to the 3750. The Router provides NAT, no NAT is done on the switch.My requirement is to port forward port 29 000 so that I can access a server on VLAN4 via this port.
So, I have: Router: Port 29000 map to 192.168.4.1 (Switch VLAN4 address)
The question is, how do I route port 29000 from the 3750 to the server on 192.168.4.42 ? what exactly I should add in order to port forward port 29000 incoming form my router, to my server on 192.168.4.42.
I have the above firewall which is working as it should but I have came across an issue with a recent upgrade to Microsoft Exchange 2007 and Outlook 2010 Autodiscovery due to the way the port forwarding has been configured for Outlook Web Access (OWA) on the router.
The router is forwarding OWA requests to the exchange server on port 8080 and the default website in IIS on the Exchange Server under which OWA sits and unfortunately Autodiscovery has been set with an SSL port of 8080. I think the reason for this is that we have an RDP server and the router is forwarding all port 443 requests to this server. Due to this Outlook clients cannot connect to Exchange through autodiscovery and cannot therefore get FREE/BUSY and a few other things.
I have 5 public IP addresses and only use two at the moment, one on the ADSL router and one on this firewall. I have no spare interfaces on either the router or the ADSL router.
My question is, is it possible to have a secondary ip address set on the public facing interface and set different rules for this IP which would allow me to forward requests on that IP to a different server?

I've created some port forwards from my public IP (Dialer0) to our private LAN but only the 25565 port forward works. I've even added an any statement to the Nat source list Homenet_NAT. Full config attached. My Cisco router is an 877W. [Code]
I just setup my homelab today, after having Cat5e installed so I can run my servers and network equiptment over wired network as well as setting up a wireless system. I got everything setup and its going great I can access everything from my office now including a E4200 Linksys router that I setup to do RiP (was only choice pretty much, or NAT), and my 891 Cisco Router which is my internet connection.
I use to have the linksys setup to do port forwarding but now I need to figure out how to do it on the cisco 891 router via command line.
Below is my current configuration. I need to be able to access my server which is behind my router by Remote Desktop. I also have a web server, and the kids also play minecraft, and have a server setup so I need to be able to forward their port as well.
Ths is from the link above, would I just do like that but then put in my IPs and is that my Private IP I use this or my public facing. Also he has "interface Dialer1 6881" again after the port in the second and third row. I dont really understand what they have there. I understand basic access list and such though I am extremely rusty.
! ip nat inside source list 102 interface Dialer1 overload ip nat inside source static tcp 10.0.0.2 6881 interface Dialer1 6881
I have a 3750 catlyst switch in my network and it is like a distubation switch,And for the nating and dhcp nomadix is using as gateway in the same network. for one of my local PC i need to config the port forwarding in 3750 switch. How to config the port forwarding on 3750 switch,
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 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.
1. a LAN with about 10 pcs, a router and a shared internet connection which is connected to the router.
2. One of the PCs is a server, and is accessed from outside. the port 2230 is forwarded to it in the router.
Now the matter is, as the server uses a shared internet connection which is always very slow,I decided to have a dedicated internet connection in the server by adding an extra NIC.but what happens is when the outsiders try to connect to the dedicated internet connection IP address,the port 2230 is not forwared to the server pc.If I dissable LAN in this PC then the outsiders are able to connect.
I am trying to port forward for Vuze and I am having a problem understanding the concepts at [URL] for working within two routers. I have a Zoom 5241 cable modem connected through a Motorola VT2442-VD for Vonage VOIP, then connected through my Netgear RangeMax WPN824v3 wireless router, to my computer. I am also running AVG internet security. Here is a look at my ipconfig /all:
C:Users ex>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : MarekFamily Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No
However, I do not understand where to setup the static ips and where to drop DHCP to be able to port forward successfully. I have tried in Vuze to set up acceptable ports 51600 for TCP and UDP, but they continue to get this error: "NAT Error - Connect attempt to 126.96.36.199:51600 (your computer) timed out after 20 seconds. This means your port is probably closed." I do know that the Ip present is from my Vonage with my external IP address. I even tried to establish rules for TCP and UDP within AVG Firewall settings for the Vuze program.
I've been having trouble signing into the PSN and Sony have given me some TCP and UDP ports to enter, I presume they're the ports for PSN. TCP Ports: 80, 443, 5223, and 10070 - 10080 UDP Ports: 3478, 3479, 3658, and 10070, When you want to open new ports on the BT HomeHub you have to fill out this form, and I don't know whereabouts I enter these ports I've been given.
I have my internet through CenturyLink which is a DSL connection running on an Actiontec Q1000 on a Windows 7 set up. I'm trying to run a subsonic server on my computer to stream my music collection. It was all working beautifully until I had to switch to this modem from my previous. Now, when I go to canyouseeme.org, it can't see that 4040 and 8080 are open. They need to be for subsonic to work? I've tried to set it up as portforwarding
At first I tried to port forward 25565 on my D-Link Router account, but that didn't work for anyone trying to connect through the External IP.
People can connect locally over my network and I can connect to the game via localhost, but like I said, no friends from abroad.
I've checked my External IP and that doesn't work, I've tried resetting my router to factory default and then reinstalling the firmware for the model, that didn't work. I tried removing the firewall altogether, and also just allowing 25565, but that didn't work. I also got my friend to take their firewall off as well.
(Also, it should be known, when I'm port forwarding I'm allowing access, and have 25565 set in both TCP and UDP. I tested to see if the port was open on Open Port Check Tool, but it said it was closed (connection timed out) even though I had it forwarded)
Router Model: TP-Link TD-W8970 port forwarding my modem/router. I previously was able to successfully port forward a Valve Source Server and had other people join on the internet so...(It worked) I recently reformatted and since have had issues.
I'm currently setup with PPPOA and I've added various ports for different programs (a Teamspeak 3 Server and Minecraft) either dont work. I used a port checker program and they either say the port is closed or the connection is refused...I've tried using a static IP but I think i configured it wrong becuase i was barely able to get the internet while using it, either way..the ports didn't open.
DCHP is disabled (Tried enabling, didn't work) The above ports are enabled with Windows firewall (inbound+outbound) and Im not using any Anti-virus software to block the ports. Windows 7 64bit, fresh format and ports that wont go through.
I am using an RV042 router/firewall -- firmware v1.3.13.02-tm -- connected to a cable modem.I have one public address (WAN1) assigned by my ISP's DHCP server.All my machines on the LAN have static IPs. (RV042 DHCP Server is disabled.)I have set up port (80) forwarding to 192.168.1.101 The HTTP port forwarding does work if an http client on the LAN sends a request to http://<public-ip>:80But I cannot get a response if I send a request to http://<public-ip>:80 from a machine on the WAN.
I did configure Access Rules to allow http traffic (and then tried to allow *all* traffic) between a single IP on the WAN and 192.168.1.101 The incoming log table shows a connection is made from the http client on the internet to the correct http server on the LAN, but there is no resonse from the LAN to the remote client.Is my configuration the problem, or is this feature not supported by the RV042 router? Could my cable modem be blocking outbound traffic?
I am trying to forward a port to see a camera over the internet. On the single port forwarding screen under Gaming, I have put in port 8090 (Ext and Int),Protocal both, an IP address and Enabled. I have also tried putting in a range, but neither seems to work. After forwarding the port, I check with What's My IP Addrewss to get the external IP, then put the IP in a blank browser page with and without the port number. I have tried this several times without any result.
I'm just setting up a Cisco rv180w router to replace our aging Belkin. I need to allow a range of ports through the firewall to a particular PC on our internal network that runs our VOIP/SIP Trunk phone system.
The Cisco's Port Forwarding looks like it can only forward one port at a time, but for our phones I need to allow a full range of ports (in this case ports 49152-64512) to one machine at 192.168.x.xx.
On the Belkin I used something called 'Virtual Servers' which allows you to enter ranges of ports. Anybody know what the equivalent might be for the Cisco router?
I've been trying to configure my router which is linksys E1000 to forward port to my sharepoint server. Here is what I have done so far, setup single portforward to i.e 192.168.xx.xx using port 4848.Now my question is, do I need to configure sharepoint to receive this incoming connection. I do need to have my sharepoint be accessed anywhere on the web.
I have set up port forwarding for my WD Network HDD, which runs a Media Server (Twonky). Now, I have tested the ports and accessed it through the internet and it works fine, until... I click a link to open a folder and suddenly I get a "No such page" error thing. I have however identified this problem, it seems that when I go off the main page it re-routes to the original network address, not my IP forward address. For Example if my IP was 188.8.131.526 and the port was 800 i would go to "184.108.40.2066:800" and it would load but once I navigate i go to "192.168.0.*:800/*****" and does not load the page. If i then copy and past my IP into the URL it works, but this is annoying.
I have recently purchased an EA4500 router. I assigned my sons XBOX a static IP via DHCP reservation (outside of the standard DHCP range). I set up single port forwarding on all the standard xbox required ports. Once I click the "enabled" box, I am unable to access the internet from any of the computers connected to the router. If I uncheck the enable box, I am instantly able to access the internet.
I recently opened the ports used by Xbox Live: Port 88 (UDP)Port 3074 (UDP and TCP)Port 53 (UDP and TCP)Port 80 (TCP)I am able to use xbox live once these ports are opened but once they are enabled, I can not get wireless internet. The xbox is connected to the router with a cable so it isn't experiencing this probem. My laptop and phone are able to identify the network and join but there is no internet access.
If I disable these ports, everything goes back to normal.
My Comtrend WAP5813n router, seems to be failing at port forwarding as I have configured it to forward ports,all the port checkers (offline and online) say those ports are open, yet I cannot access through them,it just fails to forward them(My server isn't blocking anything because it has worked on a previous router).
