Our clients have access to inside network and Internet ("hairpinning").How can I configure access to Internet on remote networks clients if VPN tunnel fail?Remote devices is ASA5505 and Cisco 861.When VPN works i have access to Internet over central office gateway.In case when VPN fail i need still have access to Internet over local (remote device) gateway.

I am trying to configure a Cisco ASA 5505 for Remote Clients.I am using ASDM interface and used the startup and ipsec wizards for my configuration but im hitting a stumbling block.For the last 2 days i have tried a number of configuration changes in attempt to make this work but failed, so i have done a factory reset and gone through the wizards again, so i have a clean configuration. Currently i have a Static Public IP Address 81.137.x.x and i am using a Netgear ADSL router, which is forwarding VPN traffic (UDP 500) to 192.168.171.35 (the wan port on the ASA 5505).The Cisco ASA has a default address of 192.168.1.1 I am using Cisco Client 5.0.06.0160.I have configured the client to use Group Authentication with the same credentials as setup through the wizard and im using Transparent Tunneling IPSec over UDP.I have attached 2 documents running_config.txt - which is shows the current ASA configuration Log-View.txt - showing error messages displayed in the real-time log viewer when i try to connect from the remote client.Im not sure whether i need to do any additional configurations for my setup other than simply run the wizards.

We have two Cisco 2960 TT-L switches. I'd like to reduce single points of failure and have dual servers for most tasks. For example, two firewall servers and two web servers. Should one server fail the other will act as a failover.I'd like to extend the redundancy to the switches, and am thinking of connecting one web server to one switch, and one to the other. In the event a switch failed a set of servers would still run, and be able to talk to each other.I'd like to run two VLANs, one for the LAN, and one of the WAN, and connect the two VLANs on each of the switches with the associated VLAN on the other switch.

I have a 5505 that i setup with a comcast cable modem (1 static address) and i cant seem to get to the internet. Im thinking it is a NAT rule but i don't have enough experience to figure it out.The current setup is E0/0 plugged into the cable modem, and a laptop plugged into E0/7. I have assigned my laptop an address within Vlan 1.[CODE]

How do I configure Cisco ASA 5505 (using ASDM 5.2) to block a workstation (IP address) from accessing internet completely? I was trying to set up a new incoming access rule for outside interface to deny any IP traffic to that workstation but it doesn't work from some reason - the workstation can still access the internet. The ASA has no special settings, only a few ports opened for servers?

I have config ASA 5505 and it is conencted to layer 3 switch that connects to cable Modem.
ASA is config with DHCP option and PC is able to get the IP from ASA. But from PC i am unable to access the internet. From ASA itself i am able to ping the Websites fine.
ASA has config with DHCP for inside and also it is doing NAT.
When i connect the ASA directly to Cable modem then pc is able to access the internet.

I am trying to “build up” a small home-network and using some of following Cisco equipment’s
ASA 5505 v8.4.3 witch base licenseCisco Catalyst 3750G with ipservices version 15.0.xand 1 qty of AP1142N I am not able to get internet access from any VRF’s.
From "MILAN (LAN) VRF, I am able to ping my gw: 10.45.45.1 but I am not able to ping for example: “linknett VRF”.
It seems that i am missing some NAT rules on ASA or ?
If i connect my laptop directly to the ASA, i am able to get internet access!
I am not feeling comfortable with a new ASA 8.4 code yet, so im not so sure which exact code's i am missing on ASA ...
attached digram including configuration files from ASA and 3750 sw.

I would like to restrict Internet traffic (HTTP & HTTPS) for Inside Users with an ASA 5505. I would like to setup a proxy-like system where a User/Password must be entered before the User can actually browse the web.
I know that this can be done with an additional RADIUS/TACACS+ Server. Is this also possible without any external AAA Server, so with User/PW stored on the ASA locally only?

I have configured the ASA 5505 for internet access and outside users to use two servers in the DMZ. Every thing is working fine. When I was configure VPN, I did some mistake I guess, now inside users are not able to access internet. They get an error 405. Thats an error. The request method XXX is inappropriate for the URL /. Thats all we know. Even I am not able to access the server in the DMZ from outside and I get an error : Bad Request - Invalid HeaderThese things just happend after I did some thing on the ASA. I copy and pasted the my old configuration but still insider users are not able to connect to internet and from outside I am not ableto connect to server. The weired thing is that I can user VPN with out any issues. I can connect to vpn but I cant access any internal resources. Even inside users are able to ping internet addresses with out any issue.

i am looking for the best practices when using a Cisco ASA 5505 to provide NAT and protect my inside network from the outside.
I have the inside security level set to 100 and the outside set to 0, want other features can be used to protect the network from the Internet, am assuming that the security levels will ensure no traffic comes from the outside to the inside unless there is a rule that allows it.
Would any firewall policies be required to increase the level of security?

I am employed at a small business, 30 employees, and they just fired the IT "liasion". Guess who the new one is... So we have RF barcode scanners that run off of access points that have high gain antenna's WITH NO ENCRYPTION AT ALL. We are broadcasting a wireless signal to half of Ohio with no security what so ever. No wonder the last guy was let go. So, I have Symbol/Motorola AP-4131's with are easy to serial up to and configure. Love them for their ease of use but they only transmit 802.11b. The AP-5131 access points are 802.11 a/b/g but are total hell to work on. I have serialed up to the 5131 and restored the AP to factory defaults and can access admin level through the CLI just fine. Problem is I don't know the CLI so I need to access the GUI.

I have configured and tested an ASA-5505 that will be deployed at a customer's home. The ISP cable modem will connect to the E0 (outside) interface of the ASA. All other interfaces on the ASA are configured for the inside network 192.168.5.0/24. I have created a VPN site-to-site tunnel between this ASA and the UC540 to allow 192.168.5.0/24 subnet access to the internal networks on the UC540.
The user has requested that all the network devices used by the rest of the family will only need to connect to the Internet. They will not need access to the VPN tunnel and they will not need access to the computers on the 192.168.5.0/24 inside network. I was planning on performing the following tasks to get this to work.

I have a wireless Airport Extreme on Vlan3. My problem is that I can't get internet access from a wireless client which connects to the Airport which is on the DMZ. From my laptop which is connected to the Airport, I can ping the 5505. That's as far as I get.

ASA 5505 and DMZ and Base License,"For example, you have one VLAN assigned to the outside for Internet access, one VLAN assigned to an inside business network, and a third VLAN assigned to your home network. The home network does not need to access the business network, so you can use the no forward interface command on the home VLAN; the business network can access the home network, but the home network cannot access the business network." Page 6-17.
This is exactly what I need. Mail server in DMZ, full access from internet to DMZ, and from inside network to DMZ, no access from DZM to inside network. If I good understand, this is possible with base license.
I successfully configure, internet Access for DZM and inside network, Mail server can be accessed from internet, as well as RDP on inside network. But I have problem to configure communication from inside network to DMZ. [code]

How can I configure an ASA 5505 NEM client to allow access to the Internet when the tunnel to the headend is down? I am planning on deploying back to back ASA 5505s in network extension mode but I do not want to block Internet access on the client side if the tunnel to the server should go down.

I attempted a firmware upgrade on my RV042. After an hour, the upgrade was still in progress. I now cannot login into the router using my user name and password (nor the old admin/admin). The router is functioning, but I fear it will eventually fail. How can I recover ability to log in? The Firmward Recovery program doesn't seem to be appropriate for this situation.

I have two identical ASA 5505. I can only access through https/asdm on one of the devices from same laptop. Below is the configuration of the ASA. My internal machine ip address 10.0.0.10/8. I have tried to remove and re-enter the "http" and "Crypto key" related command. Wireshark show "Alert (level: Fatal, Description: Handshake Failure)" right after I entered URL in browser-tried IE and Chrome. Java version should not be a problem as I can access the second ASA.

I can't access our ASA 5505 via SSH from the outside. I've configured this through the ASDM to allow SSH (Device Management > Management Access > ASDM/HTTPS/Telnet/SSH). I added a rule that allows SSH on the outside interface from 0.0.0.0 0.0.0.0. When I try to ssh in with putty, it says "server unexpectedly closed network connection" When I watch the logs on the ASA, it shows a Built inbound TCP connection on port 22, but then immediately a Teardown TCP connection. It doesn't show it's being blocked by any rule. Is there something I'm missing on enabling SSH?

I have created Remote access vpn on ASA 5505 (ver 8.2(5) with base license). When I connect from one machine, I can ping the internal network. But when I connect from another machine, cant.I have only decrypts on the ASA side, without encrypts. I was debugging ICMP packets with the capture feature, and saw that echo-reply packets are returning toward the outside interface, but aren't passing through it.
capture test access-list test interface outside
1: 08:54:44.298980 802.1Q vlan#1 P0 x.x.x.x > y.y.y.y: icmp: echo reply
Where x.x.x.x is LAN and y.y.y.y is the VPN client ip. The nat is ok, access lists are ok, but the packets dont pass through.I tried creating new VPN profile but the same problem, it seems that only one remote client can be active even base license allows more than 1 client.

Few week ago we purchase Cisco ASA 5505 as replacement broken Dlink DFL800. I try to configure all setting like it was on DLink, and all work fine with exception of one thing.
We have some resource like terminal server, that placed in internal network with configured static nat on ASA, some users use it from internal network and some from internet, but both of them use one DNS name for it like terminal.%company_name%.ru. all work fine for internet users when they try to reach server from internet with but internal users unable to use external ip, they even unable to ping external ip address from internal network. Yes i know that one way to solve this problem, is just to use internal DNS server so it can resolve terminal.%company_name%.ru in to internal ip address, BUT i want to know does exsist any way to "loop" trafic this way?
In DLink config there was 3 string in config that solve this problem
<IPRule Name="RDP_Terminal" Action="SAT" SourceInterface="any" SourceNetwork="all-nets" DestinationInterface="core" DestinationNetwork="InterfaceAddresses/wan1_ip" Service="rdp"
