I have one established IPSec tunnel between the host at the far end. When they try to eatablise a second IPSec tunnel to our seconf IP we get this error

I'm trying to add an access-list rule to allow internal servers to connect an outside host on a asa 5540. The hostname translates to multiple ip's. Normally I just lookup the ip address or one of the ip's the hostname translates too and use that in the access-list as the host. For some reason the actual ip's, which are a few, are not always available so using a specific ip sometimes does not work, thus the reason I have to use the hostname instead of the ip. I have 2 hostnames. www.hostname.com and subdomain.hostname.com.
This is how I normally add these rules (the ip addresses are fictive): access-list internet_access extended permit tcp host 192.168.50.5 host 84.115.57.121 eq www log
When I try to add this using the hostname on our asa I get an error: access-list internet_access extended permit tcp host 192.168.50.5 host www.hostname.com ?ERROR: % Unrecognized command
I've tried it without the 'www', so hostname.com but same error.
We are having Cisco ASA 5540 having Cisco Adaptive Security Appliance Software Version 8.0(5)23 at certain time of moment daily wer are facing latency and packetdrop wherin when I checked for ASA Interface which gives me " Input Errors" on outside interface ,so can any one tell me what are the causes to get input errors on cisco asa outisde interface.
The router 1841 is connected directly to the layer switch. the network diagram is below:
Office A --> Switch (L3) --> Router 1841 --> Internet --> Office B
However, when I transfer the file from Office A to office B, the speed very slow ( only around 40 kb/second), and there are an input error and CRC error:
Cisco-R1841#sh interfaces FA0/1 FastEthernet0/1 is up, line protocol is up Hardware is Gt96k FE, address is 0019.e02f.03dd (bia 0019.e02f.03dd)
I'm trying to open certain websites but the browser gives me this message: "Network Error (tcp_error) A communication error occurred: "Operation timed out" The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.
i'm currently studying at a college which has a website with a student intranet that is available to log in from any computer. So far it has been working well and I can log in on my home laptop and upload documents and look at presentations etc. Today for no reason when I try and log in I get the message Error Code 500: Internal Server Error and the webpage does no appear.I have had no problems previously and this has only happened today and yesterday, I went down to the college and accessed the website fine from the computers in the library but still no joy from my home computer.
I have a Cisco ASA 5540 running 8.2(5). When I dial a phone on the other of the the VPN the first time I get a blank after it rings(i.e when the voice mail get activated if someone picks the phone up), however works the second and consequent times i dial.
A little background. Two sites A and B connected via IPsec Tunnel. No problems in communication except for the VoIP issue. A Phone in on site A(172.17.168.x) and other on site B(192.168.103.x). Site A and Site B is connected via an IPsec tunnel on the Cisco ASA. First call fails. Second call works. Result of a packet trace is also the same. The UDP packet get drops when tried for the first time but subsequent ones pass.
We have ASA 5540. After setting up one-to-one nat, do I need to do anything else? static (Inside,Outside) public ip address private ip address netmask 255.255.255.255.
I have a ASA 5540 on which VPN is configured (Both SSL through Browser and Anyconnect) , everything was working fine but suddenly the webpage has stopped working and gives the page cannot be displayed error , moreover anyconnect client also fails to connect to the ip.
I have 2 ASA 5540 in our network. I want to upgrade it from 8.0.4 to 8.4.3. I want assistance in the configuration because I know that there is a change a configuration while migrating from 8.0.4 to 8.4.3.Is there any tool available on Internet that facilitates me to convert the current configuration computable to 8.4.3.
I am a little new to Cisco ASA's but we bought two new 5540's to use as a new VPN solution for our company. We want to implement Cisco Anyconnect full client and Clientless based solutions for our end users. I am having problems working with setting up access lists based on groups. I simply want to create access-lists to certain IP's based on groups. I ultimately want to get to the point where we have Dynamic Access Policies that are based on Active Directory Groups allowing access to back end servers based solely on their group membership in AD. But first I need to figure out how to just apply an ACL on a group.
We setup both site-to-site VPN and Remote Access VPN client on VPN 3005 Concentrator. We want to migrate all the configs to the new ASA 5540. Do you recommend that we migrate all the configurations for VPN client first before setting up the site-to-site VPN on the ASA or it does not make any difference?
Any method to determine the maximum number of concurrently used SSL VPN licenses (sessions) on an ASA5540 over a period of time? For instance, over a week, the MAXIMUM number of concurrent users that were utilizing SSL licenses on the box. We are trying to determine current license capacity of the device.
We are running 8.2(5) on the ASA itself, and have 6.47 ASDM deployed.
We have two ASA's 5540, running IOS 8.2(4). Is there a command to find out the password that we setup for VPN Load balancing? I recall there was a command that you type under CLI and it will display all passwords.
i need to upgrade ASA 5540 from 7.1 to 8.4 for secure connect feature of Cisco Jabber Configuration. Support forum guides that, i need to follow upgrade path from 7.1 --> 7.2 --> 8.0 --> 8.2 -->8.4 and also do a memory upgrade from 1GB to 2GB.
[URL]
I need to use this feature for only three or maximum four users in company then would i really need to do memory upgrade? or can i go with 1GB memory?also how i can get the prices of part number "ASA5540-MEM-2GB=" at cisco.com?

We're running 8.3(2) in the ASA5540. Users all over our enterprise connect to a business partner's application through the ASA/VPN. We have a class-b address space, and since the users are spread out all over the place, I have the entire class-b space as the local object in the ACL that allows traffic through the VPN tunnel.
The business partner has concerns that our entire address space is available to access the VPN tunnel. So I thought, to alleviate their concerns, to PAT all of our connections outbound to a single IP address.
How is this done in 8.3(2)? We use ASDM to configure the 5540. For example, say our class-b is 159.12.0.0 and the PAT'd IP address will be 199.30.36.6.
I've configured in an ASA5540 (8.4) access to a server in my LAN using telnet with webVPN. I've installed the ssh/telnet plug-in in the ASA and SSH access to the servers works fine but when I try telnet access I always get this error:
Could not connect to: "ip server" 23 Reason: java.io.IOException: Connection failed
It happen with any server I try. I'm not trying to access to the ASA, just servers inside my LAN that I can access with anyconnect correctly. There is a Cisco bug (CSCsq89467) saying that not configuring any Web-acl in the ASA solve the problem. Telnet always show the same error.
I have a problem with one of our IPSec site-to-site vpns.
-we use ASA5540 and the remote site uses a software based FW (steelgate borderware). -there are some old ACLs on our FW that have the remote site's IP address as an incoming node having TCP.... access to some servers on our LAN (why they didn't use static/dynamic NAT for clients of both end to have TCP connection???)
-when I try to set up the vpn the name entry of the remote site (which is optional) changes with IP address of the peer in vpn profile and it confuses the vpn, so the IKE phase1 won't establish. the name entry is because of those ACLs that have been entered in the past.
Q- How to stop ASA creating names via ASDM when adding ACLs?
Imagine the other site's network people are the most inflexible IT guys to do any changes in terms of using static or dynamic nat for their clients to have access to ours, so I can replace their FW IP address in ACL with other NAT addresses.
I Have Cisco 5540 with AIP-SSM-40, recently i config AIP-SSM-40 to capture all traffic from all interface any to any with promiscous mode and if card fail traffic still flow throuh asa, but after that i can't login to cisco ASDM, the error is "Un Able To Launch Device Manager From xx.xx.xx.xx"
I have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. I saw some high cpu utilization bugs, but none looked to be relevant. How I can find the root cause of the CPU high utilization?
Just upped our external ASA-5540 pair to 8.4(1), and now one of our nat's is busted.
Here's the lowdown:
Our public IP for our IronPorts ends in .167. That IP is natted to a VIP on our ACE, which load balances to the IronPorts.
The outside interface of the ASA uses .162, which has been the pat for all outbound traffic for a few years... except for the subnet that houses the IronPorts. Due to reverse lookup, that subnet uses the .167 IP address for all outbound traffic.
After the code upgrade, the nat won't work. No email sent or received. Nothing but Deny's on the ASA with flags reading either "SYN" or "RST". IE: Apr 27 12:56:11 10.22.151.41 local5.crit %ASA-2-106001: Inbound TCP connection denied from 69.25.174.17/36917 to 207.236.211.167/25 flags SYN on interface outside
If I return the subnet pat back to the outside interface, then inbound traffic works fine, though reverse lookup fails and anyone running a reasonable spam filter won't send to us.
To test the VPN performance of ASA 5540, I will have to build at least 1000 VPN tunnels. It is time-consuming works if I put all of commands line by line manually. It looked like a bundle of VPN tunnels won't be created by ASDM. I am wonder if there is any generator tool for this. I just tried to google it. I found a software is named as VPN Configure Generator, but it is not free.
I have a Cisco 5540 that terminates one end of a L2L tunnel, the remote end is a Sonicwall TZ100. The tunnel is in place to carry voice traffic and I have a need to decrypt the traffic that's been captured in .cap file using Wireshark 1.8.5. How to go about getting the session keys from either device?
I have two Cisco ASA 5540, these ASA running ver 7.2. and used mainly as VPN gateways.My question is simple, Apart from the extra AnyConnect client functionality and the higher encryption, is there any specific security benefits (related to the VPN use) for upgrading to ver. 8.x ?
I have to use GNS3 for simulate ASA5540.but it does not work. I've installed latest GNS3(0.8.3.1 all in one) in Win7 32bit environment, and used IOS file is asa842-k8.bin.but i can't unpack it properly. it said "Couldn't find any ZIP header in asa842-k8.bin".
I have two ASA 5540 working in Active/Standby mode. After I've upgraded them to 8.2.3 ver. I have the following issue: once a day presently active device arbitary reloadI have no err in show version and in syslogs:11:15:50 ASA : %ASA-6-302020: Built inbound ICMP connection for faddr 10.10.0.36/512 gaddr 10.0.0.16/0 laddr 1011:15:58 ASA : %ASA-1-104001: (Primary) Switching to ACTIVE - HELLO not heard from mate.
I have two Firewalls one on MAIN site and another on BR site. I have configured RA VPN for both and i am able to access the internal networks of respective Firewalls. But the requirement is i want to connect to the Main site through RA VPN and access the BR SITE internal networks through that connection.
We currently have an ASA with site to site VPN and anyconnect VPN being utilized. We received a third party cisco router which will be used to initiate their own site to site VPN from inside our local LAN to their LAN through our ASA.
1. Would NAT Traversal be required on our ASA? 5540(config)#crypto isakmp nat-traversal
2. Would the ports listed below interfere with ports for site to site VPN and anyconnect VPN?
SSH - allow access from xxxxx on TCP Port 22 ICMP - allow access from xxxxx - protocol 1 ISAKMP - allow access to xxxxx on UDP Port 500, also add UDP 4500 for NAT-T
