Cisco Firewall :: How To Filter By MAC Address With ASA 5510

Mar 3, 2013

I am using an ASA 5510 firewall in routed mode.How can I filter incoming traffic by mac address on the AS 5510 ? I have already setup a static access rule for rdp users on the outside to access a terminal server on the inside.Now, i would like to further limit access from specific computers only.

Cisco Firewall :: 5510 - Filter Internet IP Address Allow To Initiate VPN Connection

Apr 10, 2011

Using Cisco ASA5510 Security Plus (Post May 2010) with 8.2(1)
 
I was trying to limit the number of internet IP Address that can initiate Remote Access VPN connection to the firewall. I have plan to only allow internet IP Address from few ISPs for control.
 
However, blocking AHP, ESP, ISAKMP, NON500-ISAKMP, and IPSec Over TCP Port Assigned in the firewall outside interface doesn't work. But it works by putting the ACL in the router before the firewall. It seems that the  firewall have a "hidden" process VPN first before user entered ACL (or explicit rule), similar to Checkpoint FW's implied rule. How to get around it?

Cisco Firewall :: ASA 5510 - Single Address NAT From VPN

Jan 17, 2012

We have an ASA5510 running version 8.25. This is in our central office in London. The London network has an ip address range of 10.110.128.0/22. Connected to this via a site-to-site VPN we have a satellite office that has an IP address range of 172.16.148.0/22.
 
We have now connected to our parent company via another site-to-site VPN connected to the same ASA5510. Their network has an internal range of 10.110.18.0/24. It was our parent company that issued us with our range of addresses a long while ago so that it all fits in with the rest of the company.
 
We have resources (web servers) on their network that we use which work just as it all should. We now want to allow our satellite office to view those same web servers. The problem is that only 10.110 addresses can flow to our parent company.
 
I have configured the firewall at our central office and our satellite office to route across to our parent company via our network network and the packets are flowing just fine except that obviously once they reach our firewall they cannot go to our parent company because the 172.16.148 range cannot be routed there.
 
My idea is to NAT traffic from our satellite office to one of our local addresses before it goes over to our parent company network.
 
For example: If someone in our satellite office with an IP address of 172.16.150.5 attempts to request a resource from 10.110.18.12 then the request would go via the VPN to our firewall and then get NATed to 10.110.131.200 before being passed on to our parent company network.
 
My question is what would the NAT configuration be to achieve this. I just cannot work out what type of NAT I would need or how to construct the command. It's probably PAT as it will be multiple addresses to a single address. Essentialy, all traffic from 172.16.148.0/22 destined for 10.110.18.0/24 should get NATed at our firewall to 10.110.131.200 before being passed on.
 
Just to add, we already have this working from our Cisco 3000 Concentrator which is now going to be phased out hence trying to get this to work on our ASA. The satellite office has now been moved to the ASA and as of today our parent company has been moved to the ASA.

Cisco :: ACS 5.2 - How To Filter By IP Address

Jan 31, 2013

Using ACS 5.2, under Network Resources>Network Devices and AAA Clients>, I can only filter by:

Name
NDG:Location
NDG:Device Type
Description
 
How can I find a device by its IP Address? or how can I enable this option?
 
On this link:[URL] I read the following: ''Network Device Filters—Based on the AAA client  that processes the request. A network device can be identified by its IP  address, by the device name that is defined in the network device  repository, or by the NDG'.....
 
How could I do this on my ACS server?

Cisco Firewall :: ASA 5510 Server's NAT Address Not Changing

Nov 16, 2011

I added a new server and created a new static NAT assignment on the ASA 5510 to the server's IP.  When I browse to the web to check what public IP it's reporting, it shows the wrong IP.  I disabled the network interface on the server, ran "clear xslate", reenabled the network interface, ran "sho xlate" and while the correct translation was in the table, the server still reported the wrong IP address.I even ran a packet trace and it showed the IP address being correctly translated to the proper public IP, but when I browse to the web I get the same erroneous public IP. [code]

I have just started to use an ASA 5510 for my network. I use the DHCP server on it and after i made the change over to ASA hosts started loosing their IP address. This was not a problem before on my old firewall that aso had the roll of DHCP.
 
Is it possible that something is wrongly sett on the asa? All traffic is flowing normaly when this does not happen.

Cisco Firewall :: ASA 5510 Address Translation Through Internal Network

Jan 19, 2013

Is it possible to perform static Nat's through an internal network?I have a ASA 5510 with a public outside interface (let’s call it 68.68.68.1), and I have an inside private IP address (192.168.1.2/24). The inside IP address leads to a 4900m with that interface being configured with a 192.168.1.1 (no switching). On the 4900 M I have several VLANs one of them is an internal DMZ of sorts. (192.168.2.0/24). Within this DMZ network are several Web servers which need to be associated a public IP address (68.68.68.x).

Every time I configure a static Nat to associating a public IP address with an internal IP address within the DMZ, packet Tracer on the ASA informs me that the packet gets dropped at the static Nat and I cannot figure out why this is so.Safe it to say my question still stands is it possible to Nat (68.68.68.222 to and 92.168.2.60) given the configuration above, and how would I go about configuring in such the manner above so that I acn apply static nat through the 192.168.1.0 network to reach the 192.168.2.0 network.

Cisco Firewall :: ASA 5510 - Two Separate Address Pools On Same Interface?

Dec 25, 2012

We have an ASA 5510 and we also have two separate address pools which have been provided by our ISP.  The addresses are not contiguous.  Is there a way to configure an interface on the ASA to handle both sets of public address pools?  If the outside interface is set up on eth0/0 would I create two subinterfaces (eth0/0.1, eth0/0.2) and assign each subinterface an address pool?  Then just NAT/PAT to my heart's content?   At that point I would want both to route to our inside network.  So it's basically two inbound sets of IP addresses comming into one interface and then comming into the network...  Right now the outside interface is configured with our first set of IP addresses.  We wanted additional addresses and when we called our ISP they told us we already had them - just a different pool.  Hence the question.  I'm guessing that I wouldn't put anything specific on the outside interface and I would put the specifics on the subinterfaces?

Cisco Firewall :: 5510 - Duplicate IP Address With ASA Inside Interface

Apr 5, 2012

We've had issues with our Exchange 2010 server (running on ESXi 4.1) since its default gateway was changed to our new ASA 5510.  They manifested as frequent Outlook client connection dropouts or as IP address conflicts whenever Exchange was rebooted.  The temporary fix was to disable the Exchange server NIC, bounce the ASA and enable the server's NIC again.  We saw poor performance from Exchange after a while again, but after some research and testing I realised that disabling proxyarp on the inside interface fixed the problem permanently.
 
However I've now realised that the client VPN no longer routes properly because proxyarp is disabled on the inside interface, so I still have a problem.

Cisco VPN :: 5510 VPN Filter And Service From Remote Clients

Mar 21, 2012

We have remote VPN setup with Cisco ASA 5510. By using VPN filter, I can follow the guide and make client to use all necessary server services. (dns, ssh etc). However, is there any way that allow inside server access remote VPN client's services, ex. let inside server ssh to remote VPN client? Consider remote access VPN filter ACL's syntax, I have to always let source be the "remote VPN client PC", the dest is "inside firewall server", how can I let the other way traffice going?

Did Mac Filter Wireless Adapters Address

Sep 17, 2011

Im using my upstairs neighbors wifi with permission. It has no protection whatsoever but recently i havent been able to use it anymore, and they both just went on vacation yesterday. Their dad was there for a day or two before they all left, my assumption is he thought i didnt have permission and did something to prevent me from connecting without mentioning it before they left.Its full bars (its directly above me) but the router almost instantly doesn't respond when i try to connect. Did he mac filter my wireless adapters adress? I tried changing my mac address on my wireless adapter (aka, desktop, as it doesn't have a nic) but Tmac cant change it successfully. Tmac is able to change my laptops mac though, but even after doing so i still cant connect to the network.

Other issue - right now im using a crappy 2 bar connection called ddrtvap on my laptop. The laptop sitting right where my wireless adapter for the desktop would be and it connects fine, but my desktop cant connect to this network (it connects to the network, but no internet) while the laptop does just fine. Windows repair is super usefull as it tells me something is wrong with my adapters settings but gives no clue as to what.

Cisco Firewall :: ASA 5510 - Data Center Move / IP Address Change

Nov 4, 2012

We will be moving to a new data center in the very near future and with them our WAN IP addresses will be changing. Any best course of action for changing the IP addresses throughout the firewall configuration? Would it be possible/suggested to export the running-config, make the neccessary changes, then import the config? I am familiar with the ASA 5510 only so far as changes are required. It is not something I work with on a regular basis.

Cisco Firewall :: ASA 5510 Static Map - Outbound Flows Through Global Address

Nov 30, 2011

I have an ASA 5510 running version 7.0. I have a problem with an exchange server using a static map and its outbounc connectivity. It connects outbound through the global address even though inbound connectivity works fine through the static mapping. The recent changes are changing of the zero route through a different interface (there are to circuit connected to this ASA on different interfaces). So the idea was to get all workstations in the office using the global address and routing out through one circuit, and the servers connecting in/out through the other circuit. Shouldn't a static mapping ignore what the zero route is?
 
Here are what I believe to be the relevant configs.
 
interface Ethernet0/0
description New 6mb circuit
speed 100

[Code]....

So exchang2 server can be connected to from the outside properly via IP xxx.207.51.231/exchange2-outside, but all outbound connections from this server are going out via IP xxx.122.47.218/circuit-6mb as do all the workstations due to the global address statement.

Cisco Security :: C3800 / Filter Traffic By Mac Address?

Jan 23, 2011

Is it possible to configure cisco router like C3800 or catalyst switches like C4500 or C2960  to filter traffic based on allowable mac addresses only? I would like only to allow those devices that belongs to the domain, meaning if a user connects a computer or any devices that concerns network which I have not allowed the mac addresses, it will be denied access to the network. However, any of the allowable devices could able to use any port of the switch, meaning I dont want to associate an allowable Mac Address to a physical port on the switch.

Cisco Routers :: RV220W Filter Mac Address List

Feb 5, 2013

We have a wifi router RV220W and we need to filter the mac address. The problem is that the number of the "allowed" devices is around 50 (not all connected at the same time), but the maximum number of mac address which can be listed in this router for each VLAN is 20, so for the moment we set 3 VLAN, each one with a different mac adderss list. This is very awkward because the area to be covered by the wifi network is large and we need repeaters, but having 3 VLAN we should put 3 repeaters for each point. Is there any way to configure this router in order to have a single VLAN but with a mac address filter list of 3 x 20 mac address?

D-Link DIR-655 :: Invalid MAC Address In Network Filter

I installed the 2.06NA on my DIR-655 router and now I'm having problems adding mac addresses to the network filter. The message is "Invalid MAC address". Of course, it doesn't tell me which entry is invalid and I have a number of them. After further checking.. I noticed that one of the MAC addresses is indeed invalid and when I remove it I still get the error message?

D-Link DIR-825 :: Network Filter - Invalid Mac Address

Dec 29, 2009

I had no problem running both 2.4 and 5.0 Bandwidth. With WiFi password and without. It does it's job. The 2.4Ghz Range Plus works. I have set up the router on the 2nd floor at the highest it can go. And everyone get's full bars all over the house. I even get 4-5 bars outside in my car on my phone.

The only issue I have with this thing is a damn new netbook I got for Christmas with a Mac Address starting with 0C-EE-E6-XX-XX-XX. The Router finds the Mac Address invalid. In which I can come to understand cause seeing a Mac Address starting like that is completely new to me. Every Mac Address I have, started with 00 except the netbook. So now, I spent days trying to find firmware updates, patches, anything! I even attempted to spoof the Mac Address on the netbook but Microsoft has a bug on Windows 7. (I have the Starter Edition that came with the netbook)
 
Windows 7 Mac Spoofing works with WIRED Connection. But it does not work with WIRELESS Connection. I used 3rd Party Tools: SMAC and etc... I attempted Registry Edits, I changed even the value key to the "Orginal Mac Address" and it just wont change [New Strings/Network Address Edits included]. I have been banging my head about this for a week now. The Internets has many answers but they did not work. So Spoofing the Mac Address is out of the question. Until Microsoft fixes this bug.

Anyway: Did D-Link release any sort of beta update/driver/firmware or anything to resolve this at all? Is there a modded firmware to force the Router to take this stupid paradox of a Mac Address?

Currently: I have the Router's WiFi Password-ed with Default Factory Settings
{Hardware Version: B1
Firmware Version: 2.02NA}.

No Access To Wifi Router - Adding Mac Address Filter?

Apr 6, 2011

I tried to configure my wifi router recently to secure my internet connection. I wanted to add a MAC adress filter, but I had to leave before I could enter them all. I thought that I wouldn't have to enter my own MAC adress since I'm directly connected to the router with a wire, but it looks like I should have entered my MAC adress, because now I can't get access to my router by typing the IP adress, as usual. I tried to reset it, but it doesn't work.

Cisco Switching/Routing :: Filter IP Traffic By MAC Address On Catalyst 4500?

Dec 19, 2012

We want to filter IP traffic by MAC address on Catalyst 4500. Since we are using bonding (active-backup mode) we need those mac addresses appear on different ports. Below are solutions that we have tried: ACL but it does not   work since mac acls only match non ip traffic (We CAN NOT use ip acl). Use a static mac address-table entry to ALLOW specific mac addresses. It does not work  either since the same MAC address needs to be seen on a different port. Catalyst 4500 does not support auto-learn option (as e.g. Nexus 5000).
