Cisco Firewall :: Users Behind ASA5505 Firewall Are Unable To Access Internet
Feb 24, 2011
I have a normal setup of ASA5505 (without security license) connected behind an internet router. From the ASA5505 console I can ping the Internet. However, users behind the Firewall on the internal LAN, cannot ping the Internet even though NATing is configured. The users can ping the Inside interface of the Firewall so there is no internal reachability problem. In addition, I noticed that the NAT inside access list is not having any hit counts at all when users are trying to reach the internet.
When i replace the ASA5505 with a router with NAT overload configuration on it, the setup works normally and users are able to browse the internet.
The ASA5505 configuration is shown below.
hostname Firewall
interface Ethernet0/0
description Connected To Internet Router

Internet ISP -> Juniper SRX 210 Ge-0/0/0
Juniper fe0/0/2 -> Cisco ASA 5505
Cisco ASA 5505 - >Inernal LAN switch.
1. Internet is connected to Juniper Ge0/0/0 via /30 IP.
2. Juniper fe0/0/2 port is configured as inet port and configured the Internal public LAN pool provided by the ISP. And this port is directly connected to Cisco ASA 5505 E0/0. Its a /28 pool IP address. This interface is configured as outside and security level set to 0.
From Juniper SRX, am able to ping public Internet IPs (8.8.8.8).
Issue:
1. From ASA am unable to ping public ip configured on Juniper G0/0/0 port.(/30)
2. From ASA no other Public internet IP is pinging.
Troubleshooting Done so far.
1, Configured icmp inspection on ASA.
2. Used the packet tracer in ASA, it shows the packet is flowing outside without a drop.
3. Allowed all services in untrust zone in bound traffic in Juniper SRX.
4. Viewed the logs when I was trying the ping 8.8.8.8 in ASA. It says "Tear down ICMP connection for faddrr **** gaddr **

Recently, I have bought an ASA 5505 firewall which I have tried to connect to my ADSL router (Modem).It is now more than a week that I am trying to get internet connection through the firewall but I still can't succeed. I have tried many advices I get from this community but I still don't know what is wrong with my ASA Firewall configuration. From inside I am able to ping the inside and outside interface with a great success. and from my laptop which is connected to the firewall, I am able to ping the both interfaces (inside and outside) but still I can't access the internet.
As I don't have a static IP address from my ISP, I have configured the outside interface to pick up the ip address dynamically. Most of the time, the outside interface get the 192.168.1.2 ip address. [code]

I have an ASA5505 running ver 8.0(2). I have configured the ssh timeout, ssh host commands and did the crypt o key gen. I am unable to access the device from the host I am allowing. Is there like ca save all command required? I am trying to use the default pix and telnet password. Do those still work?

I have a issue that i am at a loss as how to solve it. I have an ASA 5505 as my firewall. I have users from other companies who visit from time to time and are unable to use their outlook email to send messages. They can however receive messages without a problem. I also have a situation where users who use windows live to access gmail are unable to send messages.
I have narrowed it down to the fact that these uses are using ssl/tls to send the mails. I did some research and found out about the inspect esmtp setting in the ASA. I have disabled it and i still have to problem. I have also removed all outbound deny statements and still no luck.
Of note is that i can send emails without attachments. They take a long time to go out ( from minutes to hours) but eventually they do. Emails with attachments of even 10k do not go at all.
I was running image 8.2.3 and i downgraded to 8.0.5...still did not work...i upgraded to 8.4.3...still did not work. I am now back at 8.2.3.
My Firewall config is attached. I am at my wits end as to what else to try. The company has not renewed support for the device so i am on my own here!

I have 10 user license for Cisco ASA, i have to use this ASA for client connectivity. Can i do NAT of more than 10 users with this license? What i understand is NO.
But as per Below explaination looks like, i can if i am not doing default routing? Actually i just need to add a specific Route towards client DMZ interface on my ASA, no default route, so can i use more than 10 concurrent sessions with this license?

How can I filter my local lan's URL requests? Is it possible to have some sort of list like...
Default_User_Group
*.microsoft.com/*
*.mydomain.com
*.google.com
Then only allow certain ip's access to the entire internet like this...
Internet_User_Group
It would be nice to possibly be able to add the rules to users in my domain, then associate the domain account with an IP OR have them login to view webpages.

I say the answer is ten. That means ten hosts can be behind the firewall and hit the internet. The eleventh doesn't get to go out. I'm being told by a coworker that the "10" in the part number refers to the number of IPsec VPN peers.
Who's right?
I say if you want an unlimited number of users on the inside to be able to get to the internet, you need the ASA5505-SEC-BUN-K9
Mfg. Part: ASA5505-SEC-BUN-K9
Mfg. Part: ASA5505-50-BUN-K9
Mfg. Part: ASA5505-BUN-K9
Cisco ASA 5505 10-User Bundle includes 8-port Fast Ethernet switch, 10 IPsec VPN peers, 2 Premium VPN peers, Triple Data Encryption Standard/Advanced Encryption Standard (3DES/AES) license ASA5505-BUN-K9

My VPN users are able to access IPV4 resources, but not IPV6, all of my other user who are not VPN users are able to access everything V4 and V6. So my network goes:
IPV4 flow = FIOS > ASA5505(IPV4 Router) > Switch > ipv4 Clients
IPV6 flow = FIOS > ASA5505(IPV4 Router) > switch > win2k8 (IPV6 Router / Tunnel) > ipv6 clients

There is web server at the internet. The firewall ASA5505 is located at the inside edge of the edge router and the internet is at the outside edge router of the edge router. The router has already been configured can route the outside network of firewall to internet. [code]
1. I have a host at the DMZ zone of firewall and if it wants to access this web server by http, the following command lines to be added to ASA5505 good enough and anything wrong with them? [code]
2.I have a doubt here that do I need to add any command line related to the Static Mapped address of 192.168.20.10/24 like below?
access-list Outside_DMZ extend permit tcp any 192.168.20.10 255.255.255.0 eq 80.whereby the 192.168.20.10 is the static mapped address of the Host at the DMZ to Outside Nertwork. Or, any other command related with the Static Mapped address have to be added?

I am trying to provide internet access to public and private SSID's on Cisco AP541n using VLAN's connected directly to ASA5505. VLAN1 is inside interface (private) and VLAN12 is wlan interface (public SSID). The AP541n is plugged into switch port 0/7 on an ASA 5505.Port 0/7 is configured as trunk mode. I have internet access when connected to private SSID but no internet access when connected to public SSID. why I can't access internet on public SSID?

Running ASA 5505
ASA Version: asa844-1-k8.bin
ASDM: Cisco ASDM 6.2(1)
I updated my ASA with version asa844-1-k8.bin.
However, whenever I try and run the ASDM client, I get the following error:
"Your ASA image has a version number 8.4(4)1 which is not supported by ASDM 6.2(1)."
How do I get the latest version installed on my Mac desktop? I know that I can connect via the web interface and run the ASDM client, but the same error persists. I have the asdm-649-103.bin file, but cannot connect to the ASA to install (I don't recall ever setting up SSH).

I have an unusual issue, for which I can find nothing on the net similar.
Setup:
ASA5505 = > CISCO3524 => Windows 2012 server
ASA is internet edge with ACL / NAT implemented.
We are wanting to implement inbound NATs for this server - 3389. We have many other servers on the internal side of this ASA that we are NATing to. Creating NATs using the same outside IP to another server is fine, no issues. This other test server resides on the same VLAN as the windows 2012 server. All IPv6 is turned off on the W2012 server, and it can web-browse out via the ASA as well. No matter what I do, however I cannot get iinbound NAT, on ANY port to this server working. Internally from another server to this server on any port is fine, i.e. we can RDP to this server without issue, so we know this works - the firewall on this server is turned off too. This is our ONLY w2012 server on the internal side. When we run a wireshark on the server whilst testing the NAT there is no traffic, so its getting blocked somewhere.
The config of the ASA is fairly big to to santize it and remove all customer reference would take a while to make display of this secure difficult.

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 have test to access the firewall of ASA5510 with ASA845-K8/asa902-k8bin + asdm-712.bin +JAVA6 / 7, is completely no problem
When i try to install a new ASA5505 existing IOS is asdm825-k8 and also asdm-712 with JAVA7 is not allow to access the firewall with ASDM
After i type in username password, it stuck on the page loading , sometimes it will come up with cannnot to the device something like that.
telnet and SSH is no problem, i still can download the IOS with TFTP.
I think may be the java problem, because i just to connect with wrong ip and password, it also stuck in this page.

I manage to configure the firewall 5505 so that it can ping between outside and DMZ and also between DMZ and inside.
Outside and Inside are not accessible to each other because Outside No Forward to Inside.
My purpose now wants to access the shared folder by Windows Explorer ( under Network ) between for example DMZ and inside. I tried to do it but cannnot even see the Host of the other party network. For example, if I open Windows explorer at DMZ, I can't see the Host at Inside Network. Same as I open Windows Exploere at Inside, I can't see also the Host at DMZ network.
How am I configure so that I can access the hsot as well as shared folder of two sites which already can ping each other?

I have setup a Remote access VPN on my ASA5505 firewall through the ASDM wizard.I can successfully connect with the Cisco VPN client. My firewall also shows me the VPN session and shows incoming Rx packets. However, Tx packets remain 0, so no traffic is going out. My ASA5505 is configured as router on a stick with 25 different VLAN's. I want to restrict traffic to one specific VLAN using a crypto map.When I issue a ping -t command on my connected Windows box, the firewall log shows me the following message:
"IKE Initiator unable to find policy: Intf outside, Src: 10.7.11.18, Dst: 172.16.1.1."
"This message indicates that the IPSec fast path processed a packet that triggered IKE, but IKE's policy lookup failed. This error could be timing related. The ACLs that triggered IKE might have been deleted before IKE processed the initiation request. This problem will most likely correct itself." [code] I have really no idea what's going on. I have setup a Remote access VPN countless times but this time it shows me the error as described above.

Pix 515e 6.3.4..A web server on our DMZ is exposed for external access.There is an "A" record (webserver.yyy) on a public DNS for this public IP.This works fine for external users. url..Now I have been asked to allowed our LAN user to access the same link and I CANNOT CREATE AN INTERNAL DNS RECORD TO TAKE CARE OF THIS, which means when our internal users access that link, the request goes out of OUTSIDE interface with a NAT overloaded address(111.111.111.2) that is in the same subnet as the URL is trying to resolve. Once it knows the IP address thru DNS resolution tries to comes back in thru the same Interface(OUTSIDE) to hit the web server in the DMZ and is not able to.
1- Where does the request from an internal user to hit url is dropped?
2- what can be done to allow this type of connectivity in the PIX 515e device?
