I have a website that is hosted by our company, but when the staff goes to the outside address of th website it gets denied by ACL thus page not found.

if it is possible to block a website or ip address from an ASA 5505? if it is possible, can you give me an example of the commands to get it done?

We have an ASA 5505 and I want to block www.facebook.com for all users on the inside network. I followed the instructions laid out in Cisco support document ID 100513 using regular expressions with MPF but am running into some problems.

Once the configuration has been changed based on these instruction www.facebook.com is blocked. However I can't access any other websites except my Google News home page comes up just fine for some reason.

I have an old ASA 5505, and I'm having some trouble with Nat Hairpinning. I've done this with other firewalls before and I am having no luck now. I have an internal address that I wish to forward from an external address- so if someone goes to 123.456.789.012:3456 then it will forward to 192.168.1.244:92 (All numbers are arbitrary here- only for illustration). I have and Access Rule and NAT and PAT set up so that I can get in if I originate from outside the LAN. What I am trying to do is to have this work from inside the LAN as well- so that if I am at my desk, and I connect a device and type in 123.456.789.012:3456, it will deliver the content at 192.168.1.244:92. The problem I am having is that it just isn't working, and I cannot figure out why- When I started here, there was an address configured to work this way, and it still works- I just cannot find what is different between what I am doing and what the person who configured it did.
View 7 Replies View Relatedmy Laptop is about nine years old, HP Pavillion Pentium 4. I run Windows XP Home Edition Version 2002 SP3. I use a broadband card from Verizon that I just put in my USB (no router, etc) I'm getting a System Error Source DHCP Event ID 1002. When this happens, my computer, I believe, is going into sleep mode and I have to reboot the system. When I turn it back on and go back on the internet, all my websites that I was in are still there. The error says: The IP address lease 10.170.223.48 for the Network Card with Network address 2c3068c16ED1 has been denied by the DHCP Server 10.173.229.86 (The DHCP Server sent a DHCPNACK message)The DHCP Server Service did not extend the lease on your computer's IP address, so your computer temporarily lost its connection with the Network. I tried the ipconfig /release and ipconfig /renew. I tried going in services.msc and going under DHCP and keeping it automatic but stopping it. I called Verizon and I believe he refreshed my Network settings (I think I knew more about the topic than he did) He said it was my computer, whatever. I just tried the static IP but it didn't seem to take. I restarted and it jumped back to automatic. My last guess is it's something to do with the time frame of when it automatically obtains the address and when it expires. When I do the ipconfig /all it shows only a two hour time frame before it expires. Today I noticed that my computer shut down/sleepmode at the exact time the ipaddress was obtained. So, is there a way to increase this time between obtaining and expiring?

But still could this be bug or something? I am posting some logs when I first discovered the problem and after I granted access to the device with the MAC address 0020008E971E. I forgot to tell you, that before I decided to post here I did firmware upgrade from Hardware version A3 1.10 to 1.35NA (I bought it from US) with factory default restore. The result was absolutely the same - the messages kept coming "Access denied to wireless system with MAC address 0020008E971E". So I granted access to that MAC and checked the logs again.

I have a test ASA 5505 at home. The DHCP IP address in my real home firewall is 192.168.1.x and as you are aware the default ip address in ASA is the same. how to configure the ASA.
In the link below there is an instruction, it seems it is working for everybody except me. I followed the instruction up and the only change was assigning the IP address, which I chose something other than 192.168.1.x But after the step of creating NAT, I do not have access to the internet. [URL] Also I followed the link below, but the revision of the ASDM in the instruction does not match with mine, so I was not lucky to figure the device.[URL]
1- How can I configure the ASA 5505 with an IP address different than 192.168.1.x (at home = no incoming static IP address = DHCP on subnet 192.168.1.x for the incoming internet)I have installed ASDM 6.3 on my laptop (From work) but when I connect to the ASA it wants to install ASDM 5.7.I tried to connect to the device through ASDM 6.3 and input the IP address 192.168.1.1It takes for ever and it does not connect to the device
2- How can I connect to the device by ASDM 6.3 or any ASDM with higher version than the original of the device?
Instead of using a IP address I would like to use a host address that points to a NTP pool.An example would be:ntp server 0.north-america.pool.ntp.org Can this be done on the ASA series?

I have ASA 5505 with basic licence, v9.1, ASDM 7.1. I want to create the DMZ for a web server.
The interface 0 is for the outside network The interface 6 is for the DMZ All other interfaces are for the inside network
My ISP provided me with one public static IP address, one gateway address and a subnet mask 255.255.255.252
1/ I would like to ask which interface I should assign the public static IP address to. Should it be assigned to the outside interface 0, or should it be assigned to the DMZ interface 6, while outside interface would be configured to use DHCP?
I tried to assign the static IP address to the outside interface first, but then when I used ASDM the “Public Servers” feature to configure NAT, I get error message that the outside interface and the public address cannot have the same IP address.
2/ For the sake of peace of mind, I am thinking about using the second firewall, which would be used only for the inside network. Can I connect this second firewall to one of the inside interfaces of the 1st firewall,
I just upgraded my firewall to ASA 5505. Now, my original static ip address cofiguration is gone.

We have an ASA 5505 and are changing ISPs so we'll be getting a new static IP address. How do I change the external IP address using ASDM? (I haven't done it in 5 years so I'm rusty and just want ot make sure.) The ASA and ASDM are up to date.Am i correct in that I only need to change the external address in the configuration under Interfaces, then under Routing - Static Routes - Gateway IP I just need to enter the new WAN gateway address?

View 2 Replies View RelatedI have a couple of ASA 5505's which work fine for what they are doing VPN and all that - we have 1 DLINK DFR-700 Firewall left and I need to get a new ASA to replace this since it is old.
All this box really does is port forward external clients to 1 address on the internal lan for client software updates. Any example configs?
So lets say we have client a with IP 1.1.1.1 and client b has 2.2.2.2 - at the moment this is what happens client a and b come in through http and get mapped to the internal http server 10.10.1.2
So I need to setup about 100 clients which can come in through http only - get mapped to the internal IP and also keeping the internal server to be able to access anything outside.

I have a cable modem internet connection and my cable modem is connected to an ASA 5505. The inside interface of the ASA has an IP address of 192.168.2.2 and is connected to a Linksys router's internet port which has an IP address of 192.168.2.1. The Linksys router then has a local area network of 192.168.1.0 and all my clients are on that network. Everything is working fine except in my ASA logs all the traffic shows up as the router's external address which is 192.168.2.1. I would like to see the 192.168.1.x address of the clients in the ASA firewall. I've tried making some changes to the Linksys router but that hasn't resolved it. Is there any changes I can make on the ASA to get this to work?

There is access list allowing traffic between but hit count is 0
I am attempting to allow traffic from one vlan to another.Vlan 1 is on Interface 0/2.vlan1Vlan 2 is on int 0/3.vlan2Each vlan can communicate inside it's own vlan, and the gateway on each responds to vlan specific clients My problem is that I am unable to communicate between the two vlans. Using the ASDM packet tracer tool, I find that packets are denied by the default rule (on the second Access List lookup). It appears as if the packet never reaches the other interface. The access rules are set up to allow traffic from one vlan to another (inbound), on both interfaces. Testing from either vlan to connect to the other fails. Below are the accee-rules for each vlans.

View 5 Replies View RelatedI have a customer with a Cisco ASA 5510 firewall, an inside network containing a Genetec video recording server, and cameras installed on broadband modems throughout the area (each with a public IP). They've recently purchased Axis Q6034-E cameras that use H.264 to stream back to the video recording server. The camera has a view mode where you can watch it through H.264 or Motion JPEG. The view with M-JPEG works, but when I switch to H.264 the video stream is denied. We have allowed RTSP, RTP, and HTTP (it's setup with only http, not 443)traffic from the camera address on the cable company public network but are still being denied the video stream. The recording software requires that the feed come from the H.264 feed, so the motion jpeg does not fix the underlying issue of being able to record.
We know it's the firewall because if we install the camera on the inside network, the video feed in H.264 works to the recorder.

I am trying to lock down the VPN access on my Cisco 5520 ASA's whereby I wish not to allow users to SSH access etc on servers running on the same interface that they are VPNing into.

As a workaround I created a NAT exempt rule which then allowed traffic to the server in question however I wish to limit the traffic to only ICMP and when I do this in the firewall it does not take affect. Is this because of the NAT exempt rule?
