Cisco Switching/Routing :: Setup Port Forwarding On 800 Series Router?
Jan 14, 2013
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.
[URL]
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 would like to setup RDP on my cisco router so I can access my server from outside my network. I also have a router from my ISP that has DHCP for my external IP address and DHCP for my internal as well.

I don't see it in the menu as it was in the classic firmware. does that mean i cannot forward specific port to open a port in Transmission on a mac?
this is the only thing i see - but what i entered does not work - port is still closed.
i've a bit more complicated setup:
main house - comcast modem and wifi router <--------> guest house - WIFI bridge - ethernet cable to a WIFI router - my apple laptop. WIFI bridge is ASUS with DD-WRT firmware. i get good speed up to 20mbps/4mbps (down/up)
transmission works, but the port is closed ? doe it really matter ? what can i do to open the port (for e. "61622") ?

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.It is impossible to ask me add one by one?

I was looking for a way to connect an AUX port from a 1700 router to a 6500 switch module console port, to see the output of the Switch's on the 1700 router, in case there is a network downtime, I could see what's going on in the switch, what cable should I use ? Also, is there is any kind of documentation for this type of config what have I seen is very few info.

I'm finally jumping in over Christmas break to set up a Y network with three routers. I run a side business repairing and cleaning viruses/malware from PCs and would like the business subnet not to be able to mix with (and possibly infect) the "home" subnet.Before I knew what I was doing, I set up a simple two router "chained" network by hanging an old SMC router off my main Airport Extreme router, but I've since learned that's not ideal, since the "work" network machines can see everything on the "home" network. So, here's what I want to do. I want to put the new third router right after my cable modem (ISP). I want to keep my Airport Extreme and all devices attaching to it (home subnet) off one LAN port of this new router and my old SMC router off another LAN port of the new router (the test subnet). Currently, the IPs are: [code]My concern in setting up a "Y" configuration is that I have some wireless IP webcams on the Airport Extreme that are using port forwarding (both UDP and HTTP) so I can view them from wherever I am on the Internet, not just from within my home network.
What's the best way to make sure the port forwarding from devices on the Airport Extreme subnet works through the "new" router and out through to the Internet? Do I have to open the same ports on the new router? If so, does anyone have an example using the addresses above? Should I just put the Airport Extreme in the DMZ of the new router (so everything is just passed through - or will that allow my test subnet to see the home subnet? Some other way?

I'm trying to set up my WRT54G wireless router so.i can port forward the relevant ports for my programs. I understand that you have to set up a static ip address before you can do a port forward which makes sense as you do not want to keep changing the ip address for the forwarding settings every time your network refreshes. But I cant seem to have it set up. And is there a rule that the static ip that you set should not be within the dhcp range?After setting up the static ip and setting up the port forward settings how do I test if the port is being forwarded correctly?

I've tried a few different ways unsuccessfully so thought I'd ask here.I'm trying to forward an outgoing port on a Cisco 800 series router. ie. When a user inside the network connects to the router on port 1234, it opens up the same port on a server on the Internet.

Trying to setup port forwarding for an XBox 360. Set fixed IP on XBox using IP outside DHCP range. DHCP range is .50 to .80. Set XBox to .49. Gateway is .1. Mask is 255.255.255.0.Added four port forwarding rules per directions on xbox site and also portforwarding.com for ports 53, 80, 88, 1074 to the static IP Turned off DMZ, Turned off UPnP, Turned off SPI. Windows firewall is on, running XP Pro SP3 and Win 7 Pro on other devices.Making the rules active for the fixed IP shuts off internet access for other devices.Single router (E4200 V2), switch, then remaining devices. Private IP addresses in the 192.168.xxx.xxx range. Rebooted router, same issue. What am I missing?

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 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 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 am trying to setup port forwarding on the asa. Inbound port 3062 needs to go to an address on a server inside the corporation. NO DMZ...I do not have the option under firewall to select port forwarding. I have add a nat rule before network object , add network object add nat rule after network object i am not sure who is inbound (I will ask) all customer said was certain ports need to go to certain PC's and the asiest way is to add portforwarding but I dont see the "Add " under firewall as so many posts say..

I have Cisco 2910 router that have 3 interfaces:
g0/0 - LAN
g0/1 - WAN1
g0/2 - WAN2
I would like to configure port forwarding in such way that connections to both WAN interface on identical ports will be redirected to a single host in a private network. When I issue command: ip nat inside source static tcp 10.10.10.X 8080 interface g0/1 8080 everything is fine, until I add the second command: ip nat inside source static tcp 10.10.10.X 8080 interface g0/2 8080
After that, the first statement is just replaced by the second one, not added to configuration.

I have a small network in my garage, it's basically made up of a bunch of test servers. Those and a win xp machine are all hooked up to a switch, and the win xp machine also has a wireless usb stick that is connected to my wireless router, and is being used to share internet to the rest of the machines. The test servers along with the NIC card on my win xp machine sit on a different subnet, however.When I remote into the win xp machine from my house, i can run a second remote desktop in the first session, into any of my servers. I want to do work on them, but its very laggy.
Is there a way I can setup a port either on the win xp machine or my wireless router so that i can remote directly into one of the servers? so if the win xp machine has a wireless ip address of 192.16.13.102, and one of the servers on the 2nd subnet has an internal ip of 192.2.2.4, can i have it so i can make, for instance, 192.16.13.102:6333 forward to 192.2.2.4? If not, is there any other way i can directly remote into one of the servers, by passing the first remote desktop into win xp? What settings would have to be the same across the line?

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?
