Cisco VPN :: Exclude IPs To Port Forwarding On 877 To ASA5505
Feb 13, 2012
I have the following setup:
ADSL ---> Cisco 877 with connected site-to-site VPN's ---> Cisco ASA 5505 with Remote VPN enabled
I want to connect my Android phone to the Cisco ASA 5505 with Remote VPN. When I forward port 500 and 4500 on the Cisco 877 to the Cisco ASA5505 I can connect with the phone.
But as expected, the site to site connections are lost because now they try to reach the ASA 5505 also.
I want to exclude the site to site external IP addresses from doing static NAT to the ASA 5505...how can I accomplish this ?

I have a Windows 2003 server running a L2TP VPN server on it. I'm putting theASA5505 in replacement of an open source firewall.
My question is that, I can't seem to forward the ports correctly for L2TP to the internal address of the 2k3 VPN server. It seems to me that the ASA is trying to negotiate the VPN connection rather than forward it internally.
Cisco ASA5505
WAN 216.136.1.2
LAN 10.1.1.1/24
Windows server - 10.1.1.14
I've added the NAT and ACL and still nothing.

I'm not able to access my Slingbox from the outside. I've set up port forwarding on port 5001 to allow outside connections in, but port forwarding isn't working. Am I missing something?

subnet 10.10.10.0 255.255.255.0
object network Slingbox
host 10.10.10.254

I have an ASA 5505 on a job. It is a smaller business that would have done better with an RV082, but they have what they have. It is running firmware 8.4. The client needed ports forwarded for their FTP server. The port range in this config is tcp 43333-43339. The FTP server ip is 192.168.1.2. [Code] ......

How to configure this setup.I have an ASA5505 with dual wan failover, FiOS (eth0) & Cable (eth1). how to configure the port forwarding for all my devices so it doesn't matter what external interface the traffic is coming from. For example, I need web traffic on port 80 forwarded to 192.168.1.150 regardless of whether it is coming through eth0 or eth1.

I have installed ASA5505 in the network. Port forwarding has been done for one of the server in our LAN. Public users are able to access the server successfully. I am trying to access from inside using the same Public server IP, but unable to access it. Can I have this feature in ASA5505(I think it is loopback configuration). If so, may I know the configuration detail?

configuring the ASA particulary after the change to how NAT is implemented. What I am trying to accomplish logically seems fairly simple, yet I cannot get it to work. I have a Synology NAS at home that I am trying to reach via the internet. Prior to using my ASA, I had Verizon's FIOS router as my gateway and everything forwarded with no issues. The ports I need forwarded or reachable via the internet are TCP port 80 and 5000.I can also configure it via command line if that's the easier/preferred method.

ASA 5505 Firmware 8.3(4), ADSM 6.4(2).I have a public IP address of 168.87.3.4.I need to forward ports (5060, 5080, etc.) to one internal address. (192168.1.1).I need to foward different ports (10020-10080) to a different internal address (192.168.1.2) Everything I read tells me how to do this in a 1 to 1 static NAT.

I have configured a SVI in my 4500 ( Sup 7-E 10GE,,,,,,and,,,,,cat4500e-universalk9.SPA.03.02.00.SG.150-2.SG.bin) switch and it is showing Down Down, because there were no active switch port in the vlan, I added one switch port to this vlan but this port also in the down state, so i added the SWITCH PORT AUTO STATE EXCLUDE command under this port, even after this also the SVI never came up, So i added one systen to the port so both the switch port and the SVI came up...So why SWITCH PORT AUTO STATE EXCLUDE command have no effect in this model of the 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.

So here is my network.
ASA5505--->Cisco1841--->Cat2960
Code
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 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)
ON ASA
object network ROUTER
host 10.10.1.1

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

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.

8.4(3) I need to outside PAT all incoming UDP (SIP/RTP) traffic from outside to an internal IP. The following command makes it work:
nat (outside,inside) source dynamic any obj-10.0.0.173 service udp udp
But it breaks DNS resolution from inside. If I add the above command and try to nslookup from inside to an outside DNS server 64.90.175.90, DNS times out. If I remove the above nat command, it works again. It seems like even though DNS UDP originates from inside which should create a statefull connection, ASA still messes with return DNS responses.I then tried to create an "exclusion" for that IP with the following:
object-group network nat-exclusions
network-object host 64.90.175.90
!
nat (outside,inside) source static nat-exclusions nat-exclusions
but it's not working.I also tried:
nat (outside,inside) source static nat-exclusions nat-exclusions unidirectional
Also not working.How can outside-PAT all UDP traffic excluding DNS.

I'd like to know if there is a way to exclude passed authentications for a specific username from reporting in the Authentications-TACACS and Authentications-RADIUS reports?
We have a few usernames that are used in scheduled jobs. We only need to know when they fail authentication, so we don't need to fill up the reports with every passed authentication from these accounts. Can this be done?

In earlier versions of LMS it was possible to choose i.e. the Routers category (top level) and enter a series of commands to be excluded from the comparison. In LMS 4.0.1 I experience, in several different installations, that this is not possible. It seems I can enter one exclude command beyond the defaults per category, the rest is not applied even though the feedback from the application is positive. Next time I access the Exclude Commands view, the commands I entered are gone. Is this a change of behaviour or a bug?

I'm working with Nexus 7010 - System version: 5.1(3).
For example, in the 7200 we can include or exclude an OID from the SNMP view entry using the command #snmp-server view.
How can we include or exclude an OID from the SNMP view entry in the Nexus 7010?

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!

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:
ip nat inside source static tcp 192.168.1.123 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 192.168.1.123

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 have interfaces defined on the 5505:
interface Ethernet0/0
switchport access vlan 2
interface Ethernet0/1
[Code].....
I only need one interface to connect to a single host on the inside (VLAN1) and then connect E0 to a DSL.
Is it possible (are what are the commands required) to take one of the other interfaces and create a Management port on the local office LAN?
