  How can I add a rule of outgoing traffic in ICF for Windows Update?

  Please do not ask me to change the firewall policy. My default policy for outbound connections is 'block '. Many programs to connect to internet without attention users and consumes bandwidth so I limited firewall to block strategy, but the Microsoft Update or the Windows update service is not running.

  Please suggest the creation of a rule of outgoing traffic in "Windows Firewall with advanced security" to allow Windows Update.

  This is not a third-party firewall program.

  Hello!

  If you are not able to ping to interface external of the pix from the inside of the host, but able to ping to the host outside the internal host. It is very good. As it is the safety device designed in pix, ASA. You cannot ping the ip address of the pix of the host connected to the other interface.

  Regarding the other question, please try the following command:

  Global 1 interface (outside)

  static (inside, outside)

  WR mem

  CL xlate

  Where is the free public ip address in the pool which can be used to map the pc1 inside.

  Another configuraiton seems perfect. If you have any questions, feel free to contact me.

  Thank you best regards &,.

• Traffic Shaping for virtual machines

  I'm looking to implement a virtual machine of traffic shaping, and I'm getting something unexpected. I put on the vSwitch 102400 Kbps to max out at 100 MB of traffic shaping. However, on the comments, I see the speed of the network as 1 GB. I tried to disable and re-enable the network connection, and even restart the guest but it still says 1 GB. I thought when I did in the past, it showed as a speed lower than the guest. I'm wrong, or am I missing a step somewhere?

  No, you're not wrong - the operation will always identify the virtual NETWORK card as a card of 1 GB netowrk traffice shaping will be accomplished by the virtual switch for limiting outgoing traffic to a maximum of 100 MB.

• DMVPN, deny traffic to the satellite mission

  Hello

  Maybe it's a weird qeustion but im DMVPN test with several scenarios.

  At the moment I have 1 Hub with 4 spoke, they all work properly. We test it because we have a lot of customers who do not have a fixed IP address to the outside, then an IP address changes each time, you have to configure VPN to our headquarters all over again. DMVPN appears as a perfect solution...

  Now my goal is to configure the DMVPN of all customers (speaks) at our headquarters. But I don't want guests to have access to our local network and nor, I want to have access to the other satellite mission. The only one who has full access allowed to all LAN's headquarters (Hub).

  What is the best way to achieve this? I started working with access lists or can I do it with EIGRP somehow? And make the ACL on the tunnels or the ethernet interfaces?

  Or maybe DMVPN is not the best solution? All comments and advice ar worm appreciated!

  Thanks already,

  Bart

  In this scenario, you use the better the VTI/DVTI tunnels. On the Hub, you can accept any peers with the DVTI-config VPN. The rays use traditional VTI-tunnels. The virtual model on the hub (which is used to build the-access-virtual interfaces by talk can be configured with a value by default-ACL (deny an ip) and CBAC firewall rule that inspects your outgoing traffic to allow packets back.) You can even use the zone based firewall, but this seems an exaggeration in this configuration.

• Inspection of traffic between hair-pinning VPN on a SAA with AIP SSM.

  Hello

  I want to deploy an ASA as a VPN endpoint and to use the AIP SSM module to inspect and provide protection for inbound traffic arriving on a VPN and start on another within the same ASA. I guess it's possible because traffic is unencrypted in the ASA State and must be intercepted by the class plan. Anyone who has done this or can anyone confirm that this will work?

  Thank you very much

  Wil Bowes

  If the ASA finishes the VPN, then indeed it can also inspect internally. The decryption happens before "module controls" for inbound traffic and the arrival of "control module" before encryption for outgoing traffic. If you can do it.

  I hope it helps.

• Refusing the outbound traffic

  Hey all, I'm a noobie to the PIX os.

  I read that by default, on PIX 501 all outbound traffic is allowed. I was wondering if that could be reversed. Refuse all outbound traffic except for specfic ports from the internal network.

  The pix is in an area of small office that needs just the port 80 and may 25. I want to reduce outgoing traffic to just what I said. A bit of luck to do this without an acl 100? I also read that acl is executed in the order of the config file, so if I deny all outbound traffic, will be all other acl be null and void?

  Thank you for your time and patience.

  Matt

  With the help of an ACL, all traffic may be refused.

  This ACL will stop all outbound traffic:

  access-list 100 deny ip any one

  Access-group 100 in the interface inside

  This ACL only allows outgoing HTTP and SMTP traffic:

  access list 100 permit tcp any any eq 80

  access list 100 permit tcp any any eq 25

  Access-group 100 in the interface inside

  It is true that the ACL is evaluated in the order. This ACL is the same as the first because no traffic would not be allowed. This is designed as an example and would have no real use in a production environment:

  access ip-list 100 permit a whole

  access list 100 permit tcp any any eq 80

  access list 100 permit tcp any any eq 25

  Access-group 100 in the interface inside

• your opinion on this outgoing acl?

  Hello

  I put the following ACL inside the interface of our PIX 525, v6.3 (5).

  The goal is to prevent our network to pollute the rest of the world with Korgo.

  It's my first 'from scratch' ACL (that I administer a system that has been installed by others).

  You will notice that there is a "permit ip any any", then later there "deny ip any any".

  It's because I'm confused about the scope of the Protocol parameter. TCP, UDP, ICMP, ESP, IP, all have their own protocol numbers. But, I know that designating IP include TCP and UDP.

  Specifying the IP address in the Protocol setting an ACL includes ALL issues of Protocol?

  If this is the case, my "license ip any any" statement ensures that I'm not blocking any outgoing traffic I want to allow. (This is my main concern - ensure that I don't have anything that I shouldn't be blocked inadvertently, and with the statement of ip deny, I will get hitcounts if I am away it fake...)

  THX...

  Yes, I think you have the concept now. The protocols listed on the IANA page are layer 4 protocols that run over IP. When you specify IP you intrinsically get each of them.

  A picky point: on your return, that intellectual property is not a Protocol, the IP is a protocol. It is a layer 3 protocol that runs on Ethernet or HDLC frame relay, etc.. When you create a list of IP access, IP is the basic protocol, and if you specify IP so you get everything that is built on this basis.

• Outgoing Microsoft VPN via a device ASA 5505

  Hi all

  I installed an ASA 5505 device for a client just now and they were delighted by improving stability VPN, he provided them, as they work for the most distance and VPN in all day to access their servers at the office. Recently, however, some staff members have spent more time at the office and where they discovered that they are unable to establish a VPN out to customers that are running Microsoft based on virtual private networks. The nature of their activity forced him to regularly establish the VPN to the servers of their customers to download data. They can establish successful Cisco VPN clients when they are in the office or working remotely, but they are not able to connect to the MS VPNs outside the office. What configuration changes I have to do on the ASA 5505 in order to solve this problem for them? Any help would be greatly appreciated.

  See you soon,.

  John

  Hello

  If the clients are connecting to a Microsoft VPN through the ASA using PPTP, you need to allow outgoing traffic (if there is an ACL that is applied to the inside interface) and also to activate the inspection of PPTP.

  Policy-map global_policy
  class inspection_default

  inspect the pptp

  Let us know how it goes.

• Windows incoming/outgoing firewall rules works do not (access denied)

  When I'm going to define either an inbound or outbound rule in windows firewall 7 I get mutiple messages "access denied."  I am trying to allow files and printers, sharing presets but when I cliquerai on finish, I get access denied messages.  Please notify.

  Hello

  Thanks for posting the question on the Microsoft forums. According to the description, you cannot create a rule of incoming/outgoing traffic in Windows Firewall and get a "access denied" error. We will perform a few steps and try to solve the problem.

  You have a third-party antivirus installed on the computer program?

  This problem normally occurs when the firewall services do not work correctly. All the dependency service could be the cause of the issue.

• Maximum traffic for a vmxnet3

  Assuming that there are no bottlenecks elsewhere, what is maximum penetration network traffic that a unique vmxnet3 adapter on a virtual machine can receive network?  It is 10 Gbit/s (gigabytes per second) or 10 Gbps (GigaBITS per second)

  Thank you!

  In theory and in the physical world, the maximum data rate would be 10 Gigabit/s, since vmxnet3 emulates a 10GBASE-T physical link.

  This flow is governed by physical limitations and traffic on the wire of the standard, but these do not apply in a purely virtual configuration (vSwitch and port group 2 virtual on the same host and same computers).

  Invited on the same host and vSwitch and port group are able to exceed beyond 10 Gbit/s. I know, we could think that for example the e1000, which has a link from 1 Gbps to the guest, is limited to 1 GB/s maximum. or vmxnet3 is limited to a maximum of 10 Gbps. But this isn't the case. They can easily exceed their "speed of the virtual link. Test it with a tool of network throughput as iperf a see for yourself.

  This is because only the true physically imposed restrictions do not apply in a virtualized environment between two virtual machines on the same host/port signalling group. Operating systems don't artificially restrict traffic to match the speed of the agreed line unless it is physically required.

  To give you an example, I am able to reach 25 + Gbps between 2 virtual Linux machines with a single on the same host/network vmxnet3 vNIC

  For reference, I am able to get 25 + Gbps with the test tool of network throughput iperf between two virtual Linux machines with a vNIC vmxnet3 unique on the same host/port group. (Yes, 25Gbps. Even if a vmxnet3 emule link 10 Gbps, throughput is not artificially capped without physical limitation of signal).

  Once you get to the external communication outside a host then you are limited by your physical host of ESXi links limitations.

• Traffic shaping policy

  Hello

  VC 2.5 ESX 3.5

  I know that the traffic shaping is applied and effective on the port group and that it effects network outgoing traffic only. What I can not address is the following:

  1 does the traffic between virtual machines on the same port group, on the same vswitch, on the same host of traffic shaping?

  2. made traffic between virtual machines on groups of different ports on the same vswtich, on the same host of traffic shaping?

  3. made traffic between virtual machines on different port groups, on different vswitches, on the same host of traffic shaping?

  4. made traffic between virtual machines on different port groups, on different vswitches, on different hosts of traffic shaping?

  5. that "out" really means? Coming out of the port group?

  Thank you

  1 does the traffic between virtual machines on the same port group, on the same vswitch, on the same host of traffic shaping? -NO.

  Right

  2. made traffic between virtual machines on groups of different ports on the same vswtich, on the same host of traffic shaping? -YES

  3. made traffic between virtual machines on different port groups, on different vswitches, on the same host of traffic shaping? -YES

  4. made traffic between virtual machines on different port groups, on different vswitches, on different hosts of traffic shaping? -YES

  Right (but only for outbound traffic).

  Due to the "absence" of an ACL allowing you to "ftp" the DMZ network anywhere, you're essentially limiting outbound traffic, it is explicitly "prohibit a whole" at the end of the ACL entries. Review your list 'dmz-in access-list', you will notice that there is no ftp service.

  Try this:

  dmz-in access-list allow tcp 10.0.0.2 host any ftp eq

  * You are _not_ restricting outgoing from the inside due to the "non-existent" of a single access list entry related to the interface "inside". In this scenario, the security level of 100 for the inside interface allows all traffic to all networks, the firewall is attached to access to network "inside".

  I hope this helps. :)

  1. I get no response to external IP addresses with my permit icmp echo. I have to specify what type of ICMP traffic as echo response on the end of the statement of license? I assumed not to put a specific function of what ICMP permit would allow all ICMP traffic, but I guess I was wrong.

  2. also suggestions on how to improve my access lists would be appreciated. Just because it might "work" does not mean that it is the best way.

  As I noticed that I had to have the ip permit any one to make it work, but am not sure exactly what is happening when I apply that statement to allow permit tcp statement work correctly.

  My goals are:

  allow hosts listed web traffic (including https and ftp)

  allow ICMP pings pass from the inside to the outside and the response

  allow VPN tunnels to establish

  Thank you all for your help. This forum was very informative and useful with previous posts, I'm sure it will be with this one as well.

  Dave

  The question is now that you have an incomplete encryption card on your PIX, which effectively blocks ALL outgoing traffic. Add the following line:

  > card crypto outside_map 9 match address outside_cryptomap_9

  to your PIX. This should get the traffic flowing again. Although passed by the hit counters your ACL, try to ping the host Bluff_Outside to test your ping? If so, then your config crypto says to encrypt all traffic as well, which probably won't work unless the Bluff is configured correctly. Better to make things as simple as possible while you are testing, then I recommend to take the crypto stuff for now with:

  > no outside_map interface card crypto outside

  Reading through your original post, when you access list only allowing certain protocols TCP, and you found that it did not work, was it web browsing that didn't work? If so, whether you have been reviewed by name rather than IP address, and depending on where your DNS servers, you probably also needed to enable DNS lookups via (udp port 53). MANY people forget this.

  In addition, in my humble OPINION, most of the clients that I have seen that initially only allow certain outgoing protocols, eventually find it's more pain than anything like their users say "I need to use this Protocol" and "I need to use this Protocol. Just be tired if you want to go down this road without a valid reason, you can cause a lot of extra work for yourself. What could be easier is just to make sure that your inside the subnet and only your home subnet, can get out by doing:

  > acl_outbound 192.168.50.0 ip access list allow 255.255.255.0 any

  This limited kind of all other connections rear door inside your network by your PIX and Internet connection, but still allows all your users go out and do what they want. Oh you obviously.
