Cisco Pix Syslog - details of traffic flow

Hi
We are logging to a syslog server on level informational. I see a byte count logged with each connection and I'm trying to understand what it means.
Is it the sum of in+out traffic for the connection? Or is it only one direction? Is there a way to determine bytes counts for both directions (like netflow)?
We are using version 6.3, but are in a position to upgrade if that will help meet our above requirements.
Thanks

Go through this Cisco PIX Firewall System Log Messages, Version 6.3. It will clear your doubts.

  • Cisco asa traffic flow

    Hi,
    Can somebody give the packet/traffic flow paths from a higher security interface to lower & viceversa..
    For eg: session > acl > xlate > etc...
    Are these checking different in both of the above scenarios ?

    Hi Felipe,
    But i do see find difference while reading the below URL.
    http://www.cisco.com/en/US/products/ps6120/products_tech_note09186a0080ba9d00.shtml
    I would like to know how is the traffic flow from outside to inside and inside to outside.
    Hope you go it...

  • ASA 5505, how to configure DMZ to Inside traffic flows

    Dear.
    We have a Cisco ASA 5505 with an outside, inside and DMZ interface.
    We really need all these interfaces.
    The DMZ interface has been configured to block any traffic to the inside (restrict traffic flow). This restriction can’t be disable, an error occurred when doing this.
    I will allow only one single port has access from DMZ to the inside, is that possible? And how?
    Thanks for the feedback.
    Regards.
    Peter.

    What i mean with "can't be disabled": when you navigate to Configuration/interfaces and select the DMZ interface / advanced, you can block traffic. By default Inside has been selected in the drop-down box. However, you can't leave it blank, you need to specify at least one. I can't create another, extra interfaces because the license is 3 max.
    So, my question is: can I create a rule somewhere to overwrite this setting for only one specific port? And how?

  • Cisco PIX 515E multiple ISP support in a VPN scenario

    Iam currently running a cisco 7.2 ios in a Cisco PIX 515E appliance. I have terminated two ISP links in the two ports, and I also have a inside network (LAN). I want to establish 2 Site-Site VPN tunnels using each one of these ISP links respectively (Site 1 in ISP link 1 && Site 2 in ISP link 2).
    Is this possible to achieve??

    Hello,
    This should work. Route the remote endpoint for site 1 out link 1 (using a static route) and for site 2 out link 2 (using a static route) and that should do it.
    Return traffic should work, assuming both ISPs aren't advertising the networks your interfaces are on via BGP (ie, you don't want return traffic from site one coming down the link to site 2 because that ISP is advertising that AS as well.)

  • Linksys WRT600N vs CISCO PIX 506E.... Firewall / Routing Performance

    Hi:
    I am new to the forum and was hoping to tap into some of your expertise. I have a Linksys WRT600N version 1.1 and I recently acquired a CISCO PIX 506E firewall. My question is what should I use as a firewall? Both have SPI etc. Should I:
    a) Use the 506E as a firewall and use the 600 as a wireless access point, or
    b) Use the 600 as a firewall and wireless access point.
    Do both routers have the same firewall routing performance? I want to use the storage feautre on the 600N, but if I do that and use it as a wireless access point the 600 can't get the proper time from the Internet, so my time for newly created folders and files shows they are 10 years old.
    Anyway, just thought I would post and find out what some of the experts thought and maybe someone from Linksys or CISCO. I know the 506E is discontinued and was manufactured around 2001 and the 600N is a new model.
    (Edited subject to keep threads from stretching. Thanks!)

    The PIX is a real firewall. The WRT has a firewall which mostly protects the router itself. People prefer to buy a "SPI firewall router" instead of a simple "router" even though the router firewall does nothing or little to protect the LAN. The only firewall configurations on the WRTs you can usually do is on the Access Restrictions tab. But that's usually all. The LAN itself is not protected by the firewall. You would notice this if you had a public IP subnet and ran it through the WRT: the LAN would be fully exposed to the internet. Some routers have a few functions like protection against denial of service attacks or similar. But even then this often filters only the traffic targeted at the router and not the LAN.
    The common protection of your LAN you have on the WRT is because you use private IP addresses inside your LAN and the router does NAT. However, NAT is not a security mechanism but a mechanism to solve the problem that you can only have a single public IP address but want to use multiple computers, which is why you have to use private IP addresses. Current NAT implementations usually drop unsolicited incoming traffic because they don't know to which IP address in the LAN to send it to. But the notion of NAT is to deliver and to allow connectivity. This has nothing to do with security or a firewall.
    Thus, if you want to use a real firewall use the PIX. On the PIX you can configure the traffic which is allowed to enter the LAN and which not. It is far superior in this respect to the WRT. However, as it is a older model, I cannot tell how fast the PIX is. You should be able to find the old data sheets of the PIX somewhere on the cisco website. They should mention the possible throughput. I guess it won't be an issue.
    To me another point for the PIX are the VPN capabilities which allow you to securely access your LAN while you are on the road.
    Of course, you must know how to configure the PIX correctly. It is a complex device and can be configured pretty much for anything you like. This means of course if you do it wrong you may end up with little or no security.
    BTW, there are no people from linksys in this forums except the moderators (which may be from lithium). To hear from Linksys you have to contact Linksys support.

  • Cisco Prime syslog server

    Where are syslogs stored, if I point my devices to Cisco Prime acting as my syslog server? I am running 2.0
    thanks, Jerry

    Hi ,
    As of now , this feature is not available , I mean PI will not work as syslog server.
    Syslog messages received by  PI from managed devices are found under Monitor > Alarms and Events > Syslogs
    as you are using PI 2.2 , you will be able to see all device syslog messages (0-7 severity)
    That display will show you up to 200,000 messages at a time.
    Check the below link for other related details proved by Marvin :

  • ACE - Inter-context traffic flow.

    Experts ,
    Could you please guide me for a traffic-flow mentioned below ?
    Connection flow:
    client IP 192.168.240.220 == VLAN721=[VIP 10.106.108.137] ===VLAN 537[Server 10.106.24.133]<=={User context test1}

    There are two context test1 & test2 on the same ACE box resides in a  CAT6k ..  Just curious to know how to redirect the server (10.106.24.133) context test1   to VIP (10.106.112.59) context test 2 which are not in a shared vlan ..
    context test 1

    Need to know , when the redirection will takes place here .... i feel that only if the serverfarm (L17SVWOASIS03_FARM ) goes down , then the redirect server comes into picture as per the configs attached..
    If that is the case then
    rserver redirect OASIS-SSO-STG2_OOS_REDIRECT
      webhost-redirection https://eportal-stg.publix.com/content/Associate/OutagePag
      inservice
    The highligted URL should be the VIP of the context test2 i.e 10.106.112.59 is it right ? in  this the case how send this request to the VIP , since both are in different vlan ? is it should be done with PBR (policy based routing) via CAT6k ? could anyone please share the configs?
    Or this can done with a default route to the VIP  on  the contexts?

    Also configured only the final rserver 10.99.1.217 under vlan 20 .... this made all the vip and rserver up .. but still couldnt get the required page...  there is small confusion in the first context as the vip is shown as https , but i dont see any cert and key in the customer config , so i made it as http for my test... but the second context vip is https , where i have added the certs n key as requied....
    Let me know if i am missing anything here.... Many thanks in advance...

    We are in the process of setting up an Amazon S3 network backup of the NAS server we have in our office.  We are using a Synology NAS to backup to Amazon s3, and we use a Cisco PIX 501 to secure our network.  The backup from the NAS to Amazon is going painfully slow, so I contacted Synology to resolve the issue.  After they examined everything, they think the router is filtering outbound traffic, and this is causing the upload to slow down.  I was told the upload should happen over HTTP and HTTPS, and I made sure these ports where open through the Access Rules.  There are no rules defined in the Filter Settings.
    I looked at the settings with the PDM, and I can't find where the filtering would be. Does someone have any insight to what could be happening?   I'm not too familiar with the PIX or all the network settings involved.
    Thanks!

  • IPSEC Tunnel between JUNIPER (SSG 20) and CISCO PIX 501

    I have successfully established the IPSEC tunnel with juniper firewall by using cisco Pix 501 (6.3 version). The problem I am facing, I have network layer connectivity but after time interval I am not able to send the traffic on destination IP address on specific port, but can successfully PING the destination IP. On both firewalls the IPs are permitted for all ports.

    Dear Mr.
    The same problem has occured with me.

  • Trying to understand traffic Flow in a LWAPP wireless configuration.

    I'm trying to understand at a high level how wireless traffic flow in the new LWAPP configuration. Based on what I can tell all wireless traffic must flow through the controllers prior to getting onto the LAN.
    So lets say I have a LWAPP Access Point off an access switch in a remote closet and my controller is off my core switches. I want to communicate from my wireless PC to a wired PC on this same access switch. The traffic flows from the AP down to the core switch, through the Controller and back up to the access switch to the wired PC.
    Is that correct?
    If this is true my main concern is supporting APs from a central controller across a low speed WAN. Looks like I would not want to do that...

    You're right in your assumption. Data traffic travels from the client to the AP. The AP then encapsulates this data using LWAPP and forwards it to the Controller. The WLC then de-encapsulates (?) it, processes the traffic as necessary and then drops it onto the wired LAN.
    So, in your scenario, the wireless client would send data to the AP. This would be encapsulated between the AP and the controller and then sent back again unencapsulated to the wired client.
    Regarding using this system over a low speed WAN, there are two ways of doing this.
    The first is to use a local WLC at the remote site (e.g. a WLC2006 or the new WLC network module for 2800/3800 ISR routers).
    The second is to use AP1030s which are 'Remote Edge Access Points'. These aren't quite as lightweight as the rest of the 1000 Series in that they will bridge local traffic and only encapsulate traffic heading 'off site'. They will also continue to operate if connection back to the WLC is lost (the first WLAN configured on the WLC remains up on the REAP whilst connection to the WLC is lost).
    I believe that the recommendation for these is a minimum of 2Mbps WAN connection.

    Cisco IOS on 871W is 12.3(8)Y12

    1) Isn't your default route supposed to be pointing towards the external interface?
    ip route 0.0.0.0. 0.0.0.0 192.168.1.254 ?
    2) Can you change the 'mode client' to 'mode network-extension'. Also the PIX will need 'nem enable'.
    Have a look at the following (I'm assuming you already have as your config seems to be similar):

  • Dual wan failover config: failback does not always work as expected for existing LAN traffic flows

    I have an 881 router configured with 2 dhcp WAN connections.  I am trying to configure failure detection of the primary connection (I do not really care about the secondary at this time).
    I have an ip sla/track configured to monitor the primary WAN connection, and if it stops passing traffic it removes that route, passing all traffic out the second WAN connection.  When the first connection is restored it should restore the route and everything should pass through the first connection again.  This works for all my tests except one.  If I start a ping stream from a client "ping 8.8.8.8 -t" and disconnect the primary connection it will lose a few packets but then use the secondary connection in about 15 seconds.  After restoring the primary connection all new traffic will use the primary connection, but the ping stream will then stop working (fails over, but not back).  If I stop the ping stream for a time (not sure how long is required, but my test was over a minute) it will then use the primary connection like all other new traffic.  A stop of a few seconds is not enough, and even opening up a second command prompt to ping the same target also does not work (pinging new targets works as desired).  It is as if something is caching the route/session/whatever and it has to have a window of no traffic before expiring/relearning the route.  This means any sustained traffic to the original target will not work until it is stopped for a certain time to let "something" age out.
    I need to know if there is a way to "flush the cache" (or whatever) during fail-back to force the primary route to be used after fail-back, or something else that will have the same effect.  My suspicion is that the second route gets "preferred" because the first is removed by the sla, and when the sla returns the route to the list the existing traffic flow is not aware of the route list change, using the last known good route (which now does not pass traffic).  The Issue here is that it takes a length of time for the now bad route to get flushed, which is greater than I want to have.
