Cisco Switching/Routing :: 881W - IOS Port Forwarding Commands For Port Forwarding
Apr 7, 2013
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 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 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 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

Is it posible to config port forwarding on cisco 2950 or other switchs.if such a option is there ple let me know ho to config port forwarding on cisco 2950 switch..
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,
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.
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 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.
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 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 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 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
[code]....
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 67.60.124.173:51600 (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[9987] and Minecraft[25565]) 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 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'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 82.9.12.456 and the port was 800 i would go to "82.9.12.456:800" 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.
