I'm trying to get an asa5505 set up so that our web server can send an LDAPS login to a client's server and receive the request back. The default IP our traffic goes out on is different than where I want the connection to come back in on. So, I set a NAT rule to send all traffic from a specific inside IP out a default outside IP. I also allowed LDAPS traffic from the client's server IP address in and have nat'd it back to the appropriate inside IP address. It seems to build the outbound connection fine, but then seems to drop it right away, which then seems to not allow the response back in. I've attached a picture of the log, with (what I think are) the lines in question highlighted. I'm far from a routing expert, but this seemed like a fairly easy setup.
I have a ACE module A2(3.5) installed, I am having a connectivity problem between two servers in my network. I have captured some traffic on different points in my network and from capture it seems like the problem is with this ACE module or somehow it is closing the connection.
From past few months, we keep getting Connection Timeout and Connection Failure error messages in our vendor application which connects to SQL Server 2005. Also Terminal Server 2003 keep disconnecting for every few hours.After several days of troubleshooting, we come to know that this Cisco ASA 5500 is not working properly. When I access the ASDM, it shows several warning messages.I know there is a setting option to configure TimeOut, but is there anyway to test and track the ASA 5500 regarding this Timeout issues?
I have the asa 5505 with asdm 6.4(5). my inside LAN is 192.168.0.0/24. the outside of asa is connected on lan 10.13.74.0/24 and i need over LAN 10.13.74.0/24 connect on LAN 10.15.100.0/24. i put nat rule on asa 5505 and acl rule and users from lan 10.15.100.0/24 can connect on my server, but i can't connect on from inside of asa connect on lan 10.15.100.0/24 and 10.13.74.0/24. my configuration asa is Result of the command:
We recently got a 10 meg dedicated internet fiber connection installed. I connected it to a PIX 501 firewall and everything worked fine (I tested it for a couple of weeks). A couple of days ago I got a new ASA 5505 and replaced the PIX with this device. It works, but every so often there seems to be a timeout when surfing the web whereby I click on a link and there is up to a 45 second wait and then the page loads quickly. I was not getting this before on the PIX so I'm assuming it's not a latency issue with the connection. I am the only one using this connection on the network so it's not to say that it's being bogged down. I want to roll this out to the other users on the network but not when this is happening. The configuration is below:
I have a SIP trunk in my Florida office connected to a Cisco 2851 ISR. I'm using Unified Communications Manager 8.0 and life is great.
We just opened a new office in Spain and now the fun begins. We created a site-to-site VPN tunnel using ASA 5510 in Florida and ASA 5505 in Spain. We can register IP Commuicator phones in Spain but when they make calls it shows up as a Florida call. We need it to show up as a Spain call.
We are thinking to get a SIP trunk into the Spain office but I only have a ASA 5505 over there. Can I terminate a SIP connection to it? Is this the best option? If not, what is the recommened setup?
I am having a problem with a ASA 5505. The users on the inside cannot access internet for the most of the time. When i looked over the configuration and tried a few changes i got out to internet about 5 seconds every 30 minute or so. Very strange. When i try to access internet i just get the windows post that DNS is not working properly. As you can see in my config i get all addresses dynamic from ISP.
I am not sure what to do next, i tried to set static routes, make Nat changes, static dns addresses, searching this forum but nothing works. It seems like there is a ISP problem but i have talked to the support twice today and they say that all is fine from their side. Does ASA behave like this?
I have a Cisco ASA 5505 - 50 VPN edition. I have baffling network issues that I have not been able to pinpoint and I recently started to think it may have something to do with my ASA. I'm a network administrator and I have a Cisco ASA 5505 in my home network so I can learn how to manage Cisco ASA's and utilize the Easy VPN feature so I have a always on VPN connection into work to log into servers, etc. I've been using the ASA for almost 6 months with the EasyVPN feature with no issues. My ISP is Comcast.
Within the last week my connections have been randomly dropping for about 20 seconds and then reconnecting. I have two computers on the network that have a direct ethernet run to the switch ports on the back of the ASA. When the connection drops, I see my LAN icons completely lose connectively (yellow exclamation warning) then after 20 seconds, reconnect. This is very random. I was able to get it to happen every time I connected to XBOX live and play a online game. It would almost on cue drop after 30 minutes of online gamming. Here are the steps I have taken:
1. Replaced 10/100 switch to a brand new 10/100/1000 switch from computer run in my office to the ASA. no joy
2. I upgraded the ASA to the most recent firmware: ASA Version 8.4, ASDM Version 6.4 no joy
3. I had an ethernet run under my carpet to the office, I started to think that maybe one of the cables had an issue after walking on it and vacumming causing a short. I removed all the ethernet under the carpet and installed power line over ethernet adapter from the ASA to my office. no joy
4. I checked both computers on the network for viruses. All computers came back clean after scanning wth Malwarebytes and SuperAntispyware.
5. I've watched the logs on the ASA as the LAN connection drops and I don't see error messages to troubleshoot this issue.
The only thing left to replace is the Comcast modem or the Cisco ASA. The Comcast modem is newer and only about 1 year old (rented from Comcast). Since my actual LAN connection drops and I lose connectively I believe there may be some issue with the ASA or the ASA switch ports or some sort of internal hardware issue on the ASA.
I am mapping static ip address to the local ip address.We have a bsnl broadband connection, and bsnl has provided us with one static ip address.We are using broadband modem.Now I would liket to map this static ip address to one of the private ip address which is 192.168.1.2(database server).i want to do nat above ips if i do so then i dont have no ip to assign to my outside interface.I would like to access this device over internet, by typing my public (Static ip ) given by the BSNL.security device i have is cisco ASA 5505.
I have a simple network with an ASA5505 mainly used for AnyConnect so there is little traffic. There is 1 laptop connected to the E0/1 of the ASA and then E0/0 is going to the internet port. I've noticed about ever 15-20 minutes, I lose all connection. The laptop can no longer browse the web and handsets can no longer VPN into the network. I've noticed a few seconds after performing a clear arp, all the connectinos are restored. The laptop can browse the web and handsets can VPN in again.
I have asa 5505 with security plus license, I configured dual ISP with two different ISP provider. I followed below cisco document to configure dual ISP [URL] The Configuration works during the testing, while removing the primary ISP cable from firewall. The problem i am facing is my primary ISP is down but the gateway is still up and it not switch over to backup ISP. For SLA which IP should i monitor so once my primary ISP is down it will fallback to Secondary.
I configured an ASA 5505 a couple of weeks ago. Every thing is working properly except it sends irritating messages to the syslog server. Her is an example of the message:
%ASA-2-106001: Inbound TCP connection denied from 195.215.221.56/80 to 10.70.13.90/252 flags PSH ACK on interface outside %ASA-2-106001: Inbound TCP connection denied from 195.215.221.56/80 to 10.70.13.90/2252 flags ACK on interface outside.
One of our hospitals keeps reporting that their internet is going out for a while than comes back up, sometimes they even have to reset the ISP modem for this it to work again. I upgraded and switched ISP to Time Warner Cable and figured it would essentially solve the issue, but there are still reports of internet outage and our new ISP has confirmed multiple times that their end is still up. Our ASA 5505 was configured by a previous employee, but when looking at the running config I noticed that the Interface for our ISP is NOT set to Duplex Full and Speed 100.
I have an ASA-5510 in a location that loses connectivity to the wan gateway after anywhere from five to fifteen minutes. At first I thought that the unit might be defective, but I replaced it with an ASA-5505 with similar results. A reload of the ASA-5510 will restore connectivity for the next quarter hour.
Here's the version information on the 5510:
Cisco Adaptive Security Appliance Software Version 8.2(1) Device Manager Version 6.2(1) Compiled on Tue 05-May-09 22:45 by builders
I just got a Cisco asa 5505 with the next OS and ASDM info ASA 5505 OS 8.4(3) ASDM 6.47 I configured and enter all rules to allow incoming traffic to LAN but it's not working also, I have one host inside that is configured in a second IP and create the rule to allow traffic to it but it doesn't work too.
Problem 1 I have VNC running in port 5900 tcp and I want to connect from Internet using port 6001 and this has to forware the connection to the real VNC port. In the configuration I have a few host with the same configuration but I use different outside port to get it.
Problem 2. I have a second IP with services: SMTP, HTTP, HTTPS and port 444 all TCP forwarding to a server in the LAN.
Facts: SMTP. Every time that I do telnet to the second IP looking for the SMTP port, the firewall doesn't let the incoming connection goes through and the LOGGING screen doesn't how that connection.PORT 6001 (outside)this port is configured to work with the IP in the outside internface and it was to send the incoming connection to a host inside to the real port 5900.Can any one check my configuration if I'm missing anything? for sure I'm but I didn't find it. Bellow is the configuration, I masked the Public IPs just left the last number in the IP, also I left the LAN network to see better the configuration.
I have a branch office set up were all traffic goes back to the core, iincluding internet acces.
It has been working fine for a year, but recently I have started to see the firewalls Asa 5505 closing the connection and stopping the phone from answering the calls.
I have skinny inspection turned on all my branch offices, but had to turn it off at the one site to get one of my phones to registered.
I haven't made any changes to the network that would trigger this issue, such as upgrading phone firmware.
My firewall is configured for default deny, other than Skinny (tcp 2000), do I need Skinny inspection to be turned on?
It's turned on my 5 other branches.How can I debug why the skinny inspection is closing the connection?As a separate note this phone is part of a pool of phones that shares a common DN, would this be causing the issue?

I have an ASA 5505 that during preak usage, likes to lose it's connection to the cloud for 50 seconds. The device is alive and kicking, can route between different interfaces, but it's connection to the cloud dies. This happens every 45 minutes or so during our peak internet usage.
the nastyness of the config, I was having issues getting PPTP pass-thru to cooperate, and never cleaned up after myself.
Result of the command: "show run"
: Saved : ASA Version 8.2(1) ! hostname THEMAN-ASA
My little ASA 5505 is working great The device appears to be artificially crippled and limited to 10,000 connections. This isn't a "CPU limit" it's just some fake limit in the device as far as I can tell.
The problem we have is that we are only using around 500-600 connections and CPU usage is only like 25%, and yet the connection count is pegged at 10,000 and locks us out of our network.
I am pretty sure this is because there are a lot of "dead" TIME_WAIT connections hanging around not being used. In our application we only have the couple hundred connections but they do move around a bit every now and then.
Is there anyway to get the device to ignore the "dead" connections and not count them towards the artificial limit on the device given that it's pretty clear the CPU / etc., is not utilized sufficiently. These aren't real connections, we only have a couple 100 established, they do just move around a bit however.
We are really only using 500-700 connections according to our servers, the others are just sitting in TIME_WAIT doing nothing.
My router shuts down after 30 minutes of inactivity. It starts up again when I try to access the internet but it is annoying to have to wait for it to "wake up". Is there a way to set my computer to access the internet on it's own after maybe 25 minutes by perhaps requesting a webpage, and to repeat this process every 25 minutes, thereby keeping the internet connection always open? It is an ethernet connection, not wireless.
there is a similar thread a few down that I saw. They suggested going into power management and disabling the shut down for network adapters. I did that and it didnt solve anything. So, on to my problem.It started a few days ago. Whenever I closed my laptop, put it into sleep, or hibernation, the connection to the wifi would be dropped and I would be forced to reconnect. I know it cant be my wifi because I did some tests at 3 separate locations and all resulted in the same effect. After closing my laptop, the wifi is dropped. I installed some updates from Microsoft. One in particular added the Remote Desktop Protocol 8.0. I doubt this did anything, but I figured I'd let you know. I would like to avoid have to re-install my OS and unfortunately my last back-up was a few months ago.
Lastly, my router has been doing something strange. Maybe a week ago, the signal radius seemed to have shrunk. I used to receive wifi all around my house, but now I only seem to get it when I am within 7 feet of my router. I updated the firmware. but the range is still small.
I'm working on a 892W router.To close the session between the wireless device and the router's console, the command Control-Shift-6 x is required.The Issue is that this command is not working for me. I'm using a SuperPuTTY connecting tool.
When I try to open my bluetooth software, it just keeps closing...I've tried to reinstall earlier versions but it does the same. I have a dell xps studio 16 . What other information would I need to provide for a full diagnostic?
We have two WAP2000's in our offices which we roam between depending on which office we are in. Lets call them Access point A and Access point B.Both are firmware 2.0.4.0 and have seperate IP addresses. Both are set up with two SSID's and VLAN tagging. Both handle connections just fine and can route traffic. Both are PoE and the catalyst switch reports PoE util at 25% over all of its ports.After 10 minutes of uptime, Access point B will close all of its TCP ports - SNMP, Web admin etc but does still handle wireless connections and traffic correctly. Access point A does not close any ports.I have confirmed that when the problem happens, Access point B still handles traffic just fine by checking the MAC address the clients is associated with, as well as powering down Access point A and confirming traffic is flowing. Access point B will also respond to ICMP ping after it has closed all of its management ports. I have confirmed there is no other device on the network attempting to use the same IP address as Access point B.
I have also confirmed that I am attempting to access the management ports from the management Vlan (1) - else I would not be able to reach Access Point A's management ports either. I have turned wireless management access on for Access point B and the ports close after 10 minutes of uptime from the wireless side too, so highly unlikely this is a vlan issue.I have confirmed all of the settings (bar the IP address config) exactly match on both Access point A and Access point B. The firmware revisions are the same.
Our security department wants me to close tcp ports 2001,4001,6001 and 9001. Below is part of my configuration
Interface Fastethernet0/0 IP address X.X.X.x ip access-group control out
ip access-list extended control deny tcp any any eq 2001 deny tcp any any eq 4001 deny tcp any any eq 6001 deny tcp any any eq 9001 permit any any
When they do a scan outside the company network is still shows up open. I have tried both a ip access-group in and out and it never seems to hit the ACL. The scan being done is on the f0/0 ip address.
Last week I purchased the E4200 and for simplicity, I configured it with basic settings using Cisco Connect. Today, I went into the web interface. The only thing I did was review settings and get the Routers PIN (it appears that Intel Chipset cards on Windows requires this PIN?) Close the browser (did not save any settings) and now I am completely locked out of the device. Cannot connect does not accept the wireless password. I hard reset the device, ran through the wizard. Everything was working again. Launch the browser and connected to the device closing window and balm?
I am trying to confgure a VPN connection on a Cisco ASA 5505, and I am supposed to translate the inside network from 10.200 76.0 to host 10.1.4.204, and then from that scheme establish a VPN with the host 66.179.80.108 on network 192.168.50.0/24. I was told that this Cisco ASA appliace would be able to translate the network address as a mask in order to make the necessary connection with the other site connection.
