Cisco Routers :: RV042G - Port Forwarding To 2 Different Destinations Based On Incoming Wan Port

Apr 22, 2013

how to: port forwarding to 2 different destinations based on incoming WAN port
The default HTTP service works fine: TCP80/80->
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-> 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.

Cisco Firewall :: Change Default SSH Port On ASA 5505 (port Forwarding)

Dec 2, 2011

So here is my network.
ASA asa831-k8.bin
Cisco 1841 c1841-adventerprisek9-mz.151-4.M2.bin
Cat 2960 c2960-lanbasek9-mz.122-55.SE1.bin
and here is my dilemma.
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    *               LISTEN
how do i make it listen on different port?
Here is relevent config for SSH for cisco 1841 (port forwarding)

Cisco Routers :: RV042G Port Forwarding From Public Port To Internal IP?

Oct 11, 2012

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

Cisco :: Not Enough Port Fields In Port Forwarding For Linksys E4200

Jul 16, 2011

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.

Cisco Routers :: SRP541W Set Up Port Forwarding From External Port

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.

TP-Link ADSL2+ Wireless :: TD-8970 Port Forwarding To A Different Internal Port

Mar 7, 2013

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.

D-Link DIR-655 :: Subsonic Port Forwarding / Get Machine - Port From Outside / Internet

Feb 16, 2011

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?

(yes, I've STFA, but don't know what else to do).

Port Forwarding Port 80 Blocks Internet For Everyone Else?

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.

Cisco VPN :: VPN Port Forwarding On 877?

Apr 6, 2011

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.

Cisco LAN :: 871 - NAT Port Forwarding

Jul 10, 2007

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:
ip nat inside source static tcp 1000 interface Dialer0 1000
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

DI-524 / Port Forwarding With ATT DSL?

Nov 10, 2012

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

Cisco VPN :: 877 / DMVPN NAT And Port Forwarding?

Sep 11, 2012

I have a setup with two Cisco 877's – 1 for the hub and 1 for the  spoke. The hub has a static WAN IP and the spoke has a dynamic WAN IP.  The two sites are tunneled with DMVPN and cert auth for connections via  Cisco VPN Client (terminating on hub router). All routes between the two  sites work fine – I can see through both ends via LAN IPs and tunnel  IPs. I can connect externally through Cisco VPN Client and RDP into PC's  on the spoke end via local IPs.
My issue is: I want a port forward on the hub router, pointing to the  IP (172.16.1.X) of a device on the spoke end. So using the WAN IP of  the hub router, I can reach a host on the spoke side. At this point I  cannot get this to work and feel it's related to a NATing issue. Here is  my current config for both sites:
HUB Router:
!crypto pki server vpn-ca database level names issuer-name CN=*** CA,OU=*** Services,O=*** lifetime crl 336 lifetime certificate 7305 lifetime ca-certificate 7305 lifetime enrollment-request 1000 database url nvram! 
crypto pki trustpoint vpn-server enrollment url usage ike serial-number none fqdn none ip-address ***WAN IP*** revocation-check crl rsakeypair vpn-server 2048 auto-enroll 70 regenerate! 
crypto pki trustpoint vpn-ca revocation-check crl rsakeypair vpn-ca!

Cisco VPN :: 3000 SSL Port Forwarding With ASA?

Jan 18, 2011

I'd need to protect access to a very critical web site on my LAN.To achieve this I have been thinking to use a cisco ASA, because Cisco VPN3000 appliances are out of market now.  But i do not know if I can achieve what I'd wish to do.I need (upon authentication) that an user connection to port 443 is forwarded to port 443 (or another TCP port)to my internal LAN where is the critical web site.So basically I need a feature like the WebVPN functionality of the Cisco VPN 3000 serires where you can logon.using web interface and you are forwarded to specific TCP port or you jsut type the web site where you want to go after authentication. For maximum compatibility (because users can be anywhere in the world and IPSEC or PPTP can be filtered) I'd need to do this with an SSL port forwarding.Is it possible to do this with the SSL VPN configuration options of the Cisco ASA ? Is it possible then to authorize users using LDAP group matching and authenticate users using kerberos 5 ?

Cisco VPN :: 5505 LAN VPN And SSH Port Forwarding

Jan 23, 2012

I would like to be able to do SSH port forwarding from outside to an IP address inside. Normally, this is very straighforward.

The problem now is that if I do so, then the LAN to LAN VPN stops working!.There is a LAN to LAN VPN working flawlesly (so far) between an ASA 5505 and a Cisco 861 Integrated Router. However, I would like also, to give SSH access to an IP address behind the Cisco router. The moment I do this the VPN breaks!
I attached the Cisco 861 router configuration, where the problem shows. The ASA has public IP X.X.X.105 and the router has X.X.X.105. These two are used for the VPN tunnel.

The internal network in the ASA is and in the router. These talk to each other using the tunnelt. But, the moment I try to forward port 22 in the router from X.X.X.107 to the VPN breaks! I do that with the following line: ip nat inside source static tcp 22 X.X.X.107 22.Obviously, something is eluding me. The configuration is rather short and simple. But, I'm a newbie with Cisco rotuer configuration. Note that the tunnel stays up after I use the natting entry and I can talk from the router to the ASA, but not the other way around!The router is Cisco 861 with IOS version 15.0(1)M7.

I need to allow udp port 4669 and 4769 on the router. traffic passing port 4669 should go to Server0 ( 192.168.XX.XXX) on port 4569 and Traffic passing port 4769 should go to Server1 (192.168.XX.XXX) on port 4569 and should be vice versa. like traffic coming from example server0 using port 4569 should go out on port 4669 to reach my local server.

We have the following port forwards set up on a Cisco 800s router. All internal IP addresses are NATd out to the IP on fa4 which is the external interface.  Traffic recieved on fa4 is forwarded to different servers depending on the type of traffic recieved.
We can browse the internal websites from the internet fine, but there is one internal server that uses a db server ( it accesses it on its external IP (fa4) on port 1433  but for some reason the connection does not work.. could this be because the source and destination IP addresses are the same IP address?
ip nat inside source list 1 interface FastEthernet4 overload
ip nat inside source static tcp 21 interface FastEthernet4 21
