Cisco Firewall :: ASA5505 IP FLOW TOP Or IP Accounting

Nov 8, 2012

How does one find the top user or IP accounting with this ASA5505 v7.22 device?
 
-With 1841 ISR:
-sh ip accounting
-sh ip flow top
 
Very lame if they don't have similar commands or capabilities on the ASA series.

Cisco Firewall :: Flow Export From ASA5505 To Netflow Collector

Mar 21, 2013

I have three ASA5505, two firewalls connected to central VPN hub. the central inside network is 192.168.0.0/24,Network A is 192.168.1.0/24,Network B is 192.168.2.0/24,In one of this site (central), I have server with NetFlow collector.,I will collect the traffic information from all ASA at the my one serverCan I configure source IP address (or source interface - inside) for NetFlow packet, originate from ASA? (for example from site A)If it is not possible I think, I can rewrite my access lists and permit udp traffic from outside interface to server IP like this:access-list VPNACL permit udp host <Outside IP site A> host <Inside IP the Server> eq 9996,But I do not understand, what port I must be use in access list on Central site ASA. ,access-list VPNACL_A permit udp host <Inside IP the Server> host <Outside IP site A>  eq 9996 ? or, in this place, must be source port in the udp netflow packet?

Cisco Switching/Routing :: ME3600X Ip Accounting / Net-flow

Jul 26, 2012

Struggling to find any documentation that states both "ip accounting & netflow" are supported on the new ME3600 switches. I have tried both a 12 and 15 release of software. Netflow produces no data what so ever, ip accounting only produces data (of the global network) when configured on my uplink (running MP-BGP network) unable to get specific data for user networks in seperate VRFs. Is this a case of the commands being there but not being supported?

Cisco WAN :: 2621XM / IP Accounting And / Or Ip Cache Flow Stats?

Dec 15, 2010

I have a Cisco 2621XM router with two ethernet interfaces that sits before a vendor supplied VPN router. I need to see the IP traffic incoming to my router from the WAN side (fasteth0/1 below). I setup ip cef, and ip flow ingress on the interface. However -- it seems that what I see when I use "ip cache flow" command doesn't have a very long history or life. What commands am I missing so that I can see a summary of the stats over say the last 5, 10 or 15 minutes? Is this the best config that can be used for this, or can I create a more summarized report just using the router HW and IOS? Basic current configuration:version 12.3service timestamps debug uptimeservice timestamps log uptimeservice password-encryption!hostname Littleboy!ip subnet-zeroip cef table event-log size 1024ip cefip cef accounting per-prefix non-recursive prefix-lengthip cef traffic-statistics load-interval 180!ip flow-cache entries 2048ip flow-cache timeout inactive 60!interface FastEthernet0/1 description Littleboy to vpn-wan ip address 10.1.0.1 255.255.255.252 ip flow ingress?

Firewall Access Traffic Flow

Aug 30, 2012

I've been thinking about this for a while and I can't seem to find a comforting answer: Assume you have three datacenters connected over a WAN. Each datacenter has its own Internet and firewall, and each firewall has a trusted network, untrusted network (Internet), and DMZ: [code]

-DMZhostA has inbound access from the Internet over port X.
-DMZhostB has outbound access to DMZhostC over port Y.
-DMZhostC has outbound access to the trusted network over port Z.

If DMZhostA gets compromised from the Internet, the attacker can indirectly access the trusted network through DMZhostC, assuming the services running on the given ports are vulnerable/poorly secured.How do you track this web of access? This is a simple scenario with just three firewalls and datacenters, but it gets proportionally more complex and harder to track as the network gets larger. Manually tracking the traffic flow seems tedious, slow, and inefficient.

Cisco Firewall :: ASA 5505 Traffic Flow Between Interfaces

Jun 13, 2012

I am fairly new to configuring ASA's. I have an ASA 5505 with one outside interface and three inside interfaces (inside1, inside2, and management). I need inside1 and inside2 to be able to talk to eachother but cannot work out how to make this happen. They are both configured to the same security level and the 'Enable traffic between interfaces with same security level' box is ticked. I have also tried adding appropriate NAT and Access rules. The packet tracer suggests the rules are correct for allowing traffic flow between interfaces but obviosly this may not be the case.

Cisco Firewall :: ASA 5505 Ports Available For Traffic Flow In Router

Oct 21, 2011

I am in search of a new routers. I don't have any special task to do. Just the flow of maximum 2mb/sec data and some times video conference. However I need the Voip solution as well. I just got excited on the cisco ASA 5505 product. Can this fulfill my requirements. Can this work as the router 1841. Does this support DMVPN, SSL VPN and dynamic routing. Can I upgrade the IOS for dynamic routing purpose. Do you recommend to purchase this produe act or not instead of router ? What are the limitations of this product. If I purchase this I can use this as an router as well as strong security solution. How many ports are available for traffic flow in ASA 5505. Are all routed mode or some of them switch port.

Cisco Firewall :: 5510 - Http Connection With Video Flow

May 4, 2011

I am using ASA 5510 and I have a specific problem with Http Connection to receive a video Flow ( RSTP protocol ) in the LAN. Some Pc users (192.168.1.133,in the log)  with ASA Lan Interface as gateway can ping the Camera but don't receveive the video flow.Some Pc users (192.168.1.116,in the log) using another gateway can ping and receive the video flow. I used Whireshark  to capture traffic between camera and Pc using the 2 gateway. I joined Logs with this message.It seems to be a problem of TCP segments on the ASA, I try to changed some TCP options but it's still the same:- Disable Force Maximum Segment Size- Enable Force TCP Connection to Linger in TIME_WAIT State for at Least 15 Second.

Cisco Firewall :: ASA 5520 Flow Is Denied By Configured Rule

May 28, 2013

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.  Once I get basic connectivity working.

Cisco Firewall :: ASA5580 - How To Configure Traffic Flow Idle Time-out With CSM

Feb 16, 2012

I am looking for the way to define an idle timeout for specific flows on an ASA5580 by using Cisco security manager. For ex I needed to define a specific idle timeout for connections beetween specific devices (Devices in vlan1, Device2 in vlan2).To test it I did following changes by CLI and it works fine.     access-list L1 extended permit ip <@IP1> <mask1> host <@IP2>    class-map CM1        match access-list L1    policy-map PM1        class CM1        set connection timeout idle 02:00:00
 
I try do do the same configuration with CSM in order to be able to manage each changes only by using CSM.So I defined  Access control list, Traffic flow and then I define timeout in CSM --> PIX/ASA/FWSM Platform --> Service Policy Rules  --> IPS, QoS and Connections Rules -> connections settings -> Traffic flow idle time-out. The problem is that each time I deploy the configuration with CSM I loose the timeout config line which is the most important for my application..

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.

Cisco Firewall :: ASA5505 Can't Ping New Firewall On Inside Interface

Jul 14, 2011

I've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.

Cisco Firewall :: Unable To Ping Internet IPs From ASA5505 Firewall

Jan 9, 2013

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 **

Cisco Firewall :: ASA5505 Firewall Rule Not Blocking

Apr 1, 2013

I'm trying to troubleshoot an ASA5505.
 
The original goal was to block "Mumble/Murmur" (a voip app) traffic, which runs on TCP/UDP 64738, both inbound and outbound, except to a certain host (63.223.117.170).
 
However, when nothing I tried seemed to make a difference, just to troubleshoot, I decided to try blocking all inbound traffic.  I first disconnected ethernet port 0/0 to ensure that it was cabled correctly and the outside interface went down when I did.  That worked as expected, so I confirmed I had the right interface and it was cabled correctly.
 
I then applied a "any any deny ip" rule as the first element in the outside interface access_list, as you can see below.  However, it appears to have had no real effect and the hit count is very low (it should be astronomical).

Cisco Firewall :: Using IP Aliases On ASA5505

Nov 29, 2011

Is it possible to use IP "aliases" on an ASA5505 to use as static NAT public IPs to private IPs?  For example, I have int e0/0 connected to my ISP using a /30 subnet and I have my private LAN connected to e0/1 with a /24 subnet.  At the moment I can use the one usable IP from the /30 to NAT to the private LAN.  The ISP is also routing a /28 subnet to the one public IP of the ASA. I would like to use some of the /28 IPs for NAT also.  Can it be as easy as just adding the NAT commands? I figure I would have to add that subnet to the ASA somehow, no?  In other devices (including the SA520) they use a concept called IP aliases whereby you define what additional IPs the device can use in its NAT config.  Does the ASA support aliases?  Maybe I have to do something with VLANs?

Cisco Firewall :: Routing Using ASA5505 And Pix 501?

Jun 16, 2011

I have 1 network that I'm trying to make secure, and it needs to access 2 seperate networks.   I tried using an ASA5505 that I had on the shelf to accomplish this but discovered that I had the basic license and that was prohibiting me from getting my connection to my 3rd network.  I scrapped that idea and grabbed an old pix 501 off the shelf to bring my connectivity to my 3rd network online since the 3rd network is only passing ip traffic to a small group of servers on the outside I figure the 501 should be just fine.
 
So, here's the problem I am running into:My internal network is 10.10.16.0/16, I have a new domain controller with DHCP on it handing out addresses in the 10.10.16.0/24 range.External Network 1 is 192.168.16.0/24.  The services I need from that network are primarily in 192.168.0.0 range, however there is a comcast router 75.123.123.123 (Changed of course) that provides high speed internet I need for my www traffic.External Network 2 is 10.1.1.0/16  I have about 4 servers I need to access on this network and that's it.   This network has it's own domain and DHCP controller and I've been given a range of ip's to use on this network of 10.1.3.180-10.1.3.189 My switch is just a plane jane 3com switch with minimal management so I am attempting to use my ASA5505 to handle my layer 3 routing. 
 
So here's my issue:ASA5505 (IN:10.10.16.1, OUT: 192.168.16.6):  Passes traffic to External Network 1 and to the comcast router, no problem.   All my computers on my 10.10.16.0/16 network have access to everything on 192.168.0.0/24 as well as getting full name resolution and www traffic across the comcast router.  Can NOT access 10.1.1.0/16 no matter what.  From inside the ASA or from on the inside LAN ports.  It CAN ping the PIX 501  PIX 501 (IN:10.10.16.3, OUT: 10.1.3.180)  Can ping EVERYTHING.  Can ping 192.168.0.0/24, can ping 10.10.16.0/16 and can ping 10.1.1.0/16.    Set to globally assign the other IP's in my range as addresses for outgoing traffic.Workstations (IN: 10.10.16.XXX DHCP, using 10.10.16.1 as gateway)  Can only access everything on External Network 1.  ZERO access to External Network 2. ATM I have both INSIDE and OUTSIDE ACL's wide open for both firewalls just to get connectivity going.  I will be tightening it up after it is operational.Attached find a log file (Sensetive data removed of course) that contains the sh run and sh ver for both the ASA5505 and the PIX 501.

Cisco Firewall :: Configure Dmz On ASA5505

Dec 20, 2011

I have a asa 5505 Sec plus with 3vlan, inside, outside and dmz.
 
On the outside i have 5 ip's for my use, and in the dmz i have a webserver that need to communicate with one sql server on the inside.
 
The "sql" also needs to be accessible from outside and thus has a static nat with a dynamic nat so it replies from same ip as on nat ie 72.72.72.5 webserver is natted with 72.72.72.6
 
sql inside ip is 192.168.1.2, gw 192.168.1.1
webserver ip is 192.168.2.100 gw 192.168.2.1 
sec lvl on inside is 100 and on dmz 50
 
with a dynamic policy  running inside-net/24 to dmz-network/24 translagt to dmz 192.168.2.2 i can get it to ping 1 way from inside to dmz, but not the other way around...
 
All i need is to open 1 port  ie 6677 both ways for this communication to work.
 
I'm not very familiar with the CLI and do most stuf in GUI  (know i should learn CLI, but time doesnt let me)...

on access rules i have just added everything from any to any using , ip, icmp, tcp and udp just to be sure...  :-)

Cisco Firewall :: Trying To Get ASA5505 To Route

Nov 14, 2012

customer's WAN solution, instead of buying routers, purchasing department bought ASA's (don't even get me started!). So I have 5 ASA 5505's for the branch offices and one 5510 for the Head Office. I am trying to get them to behave like routers and pass the traffic across. I set up a lab with a 5505 and the 5510 using an ethernet cable for both Outside interfaces since the WAN links are going to be MetroEthernet Layer 2 anyway.
 
I tried static routes, dynamic routing, I followed examples from other persons who did it and it doesn't work. I attached the configs here to show I have the default routes, specific static routes pointing the traffic out, any any rules configured as well. I cannot ping from the internal lan of the 5505 to the internal lan of the 5510.
