• No not removed from the external interface access-list access list?

  PIX515

  customer wanted to modify the access list (add a new line)

  so he has first publish no access-list command can

  apply the change to the access list, but the access list has been

  removed from the interface outside

  is this a normal behavior? on routers access list stay connected

  for the event of the interface if you issue no access-list command

  Thanks in advance for any comments

  JYP

  Hi Thibault-

  No, it is not a normal behavior, sounds more like an error by the customer. It's always a good idea to copy the required ACL on a text editor (Notepad) do not forget to include "access-group command" i.e. "access-group interface inside inside' or 'access-group out in interface outside' - when copying the required ACL and then issues a 'no access-list inside' or 'no access-list outside' the first line in the ACL copied on your notebook before copy you it to the PIX , also make sure that you are using the config and make an "m wr" (write memory) after the ACL modified have been applied on the PIX.

  Hope this helps-

• the conversion of the outgoing state access list

  I'm in the middle of conversion "outgoing/apply" statements to the declarations of the ACL. However, I need to add some 'free' statements more production. I'm very uncomfortable with the ACL, but I never realized how effectively use ' outgoing/apply' statement.

  How to converting the instructionsuivante ACL to a statement "outgoing/applicable?

  inside_acl list of access permitted tcp 10.200.98.0 255.255.255.0 host 194.232.23.13 eq 80

  inside_acl access to the interface inside group

  Thank you

  Mike

  Oops... mike sorry a mistake... the application should be

  apply (inside) 1 outgoing_dest

  given that 194.232.23.13 is the ip address of your destination...

  If you want to block the source and target, as it appears in the ACL, you must set 2 statements inbounds / apply:

  inside_acl list of access permitted tcp 10.200.98.0 255.255.255.0 host 194.232.23.13 eq 80

  1 outgoing deny 0 0

  1 outgoing allow 194.232.23.13 255.255.255.255 tcp 80

  apply (inside) 1 outgoing_dest

  2 outgoing deny 0 0

  2 outgoing allow 10.200.98.0 255.255.255.0 tcp 80

  apply (inside) 1 outgoing_src

  10,200 as the source IP address

  It's really a confusing task... so stick on with ACL. the rate of responses if found useful

• Setting the time on a wrt160nl

  The status page of my wrt160nl currently appears as 'not available '. Since the timestamps on the storage, I guess that when I put in place last week it thought it was 00: 00 January 1, 2009. I have configured the zone but cannot find any mode of setting time (or date), and there is nothing in the manual. Anyone know how the weather is supposed to be put in place? I guess this is supposed to know the time, otherwise access restrictions do not work. Is it supposed to be looking for a server of time somewhere?

  Thanks for your help - I think I found the problem. I use the WRT160nl as a media server, switch 4 ports and wireless access; It seems that it seems that for the moment on its 'internet' port, not on the default gateway on the local network (which is where I had assumed he would go as he knows this is where the internet is in fact). So I have now done a messy reconfiguration that is the default gateway on the 'internet' port and he seems to have found as if by magic time. Is not ideal, but it seems to work. Life would be much easier if you could telnet on the thing and know what is really happening...

• Question of access list for Cisco 1710 performing the 3DES VPN tunnel

  I have a question about the use of access lists in the configuration of a router Cisco 1710 that uses access lists to control traffic through the VPN tunnel.

  For example the following lines in a configuration on the remote router. My question is whether or not the traffic that matches the definition of list access-130 (something other than 192.168.100.0/24), cross the VPN tunnel or go directly to the Ethernet0 interface.

  My understanding is that traffic that matches the access list 120 would be encrypted and sent through the IPSec tunnel. If there was "ban" set out in the statements of 120 access-list, the traffic for those would be sent through the IPSec tunnel but not encrypted (if possible). And finally, given that the definition of crypto card reference only "adapt to 120", any traffic that matches 130 access list would be sent Ethernet0 but not associated with the card encryption and thus not sent through the IPSec tunnel. "

  Any input or assistance would be greatly appreciated.

• Access-list command not supported in the 2.2 FWSM (1)

  Hi Netpros

  I am facing a strange problem with one of my FWSM installed in my spare box 7609.

  I have a FWSM installed in live production network, in which the caught watch access list supported and I am able to set up their place, but in the alternative box, I am unable to do so when I have? to get the command supported, it doesn't either up the access-list command.

  The two boxes run upward with 2.2 (1) and on different 7609 boxes.

  Basically, I want to do the CLI or the tested features up to in my box of spare before you go and implement the same on the live production network.

  I have attached both the version of the show, but also the supporting documents.

  Pls do not help to find where I m lack somehting here :-(.

  regds

  Your spare module is configured in mode 'multiple context', where you can create up to 100 logical firewall within one FWSM. In this mode, when you the meeting into the FWSM, you enter in what we call the context of the system in which all you can do is set the other contexts. In the context of the system there is no notion of the lists of access or something like that, and that's why you can't see these commands you.

  You want to deliver the FWSM in unique context mode by running the command:

  simple mode

  Reboot and then when he comes back to the top you'll be good to go.

• IOS VPN on 7200 12.3.1 and access-list problem

  I'm in IOS 12.3 (1) a 7200 and have configured it for VPN access. I use the Cisco VPN client. Wonder if someone has encountered the following problem, and if there is a fix.

  The external interface has the access-list standard applied that blocks incoming traffic. One of the rules is to block the IPs private, not routable, such as the 10.0.0.0 concern, for example.

  When I set my VPN connection, none of my packets get routed and I noticed that outside access list interface blocks the traffic. When I connect to the router through VPN, the router attributes to the client an IP address from a pool of the VPN as 10.1.1.0/24. But normal outside the access list denies this traffic as it should. But as soon as I have established a VPN connect, it seems that my encrypted VPN traffic must ignore the external interface access list.

  If I change my external access list to allow traffic from source address 10.1.1.0/24 my VPN traffic goes through correctly, but this goes against the application to have an outdoor access list that denies such traffic and have a VPN.

  Anyone else seen this problem or can recommend a software patch or version of IOS which works correctly?

  Thank you

  R

  That's how IOS has always worked, no way around it.

  The reasoning is to do with the internal routing on the router. Basically an encrypted packet inherits from the interface and initially past control of ACL as an encrypted packet. Then expelled the crypto engine and decrypted, so we now have this sitting pouch in the cryptographic engine part of the router. What do we with her now, keeping in mind users may want political route she is also, might want to exercise, qos, etc. etc. For this reason, the package is basically delivered on the external interface and running through everything, once again, this time as a decrypted packet. If the package hits the ACL twice, once encrypted and clear once.

  Your external ACL shall include the non encrypted and encrypted form of the package.

  Now, if you're afraid that people can then simply spoof packets to come from 10.1.1.0 and they will be allowed through your router, bzzzt, wrong. The first thing that the router checks when it receives a packet on an interface with a card encryption applied is that if the package needs to be encrypted, it is from his crypto ACL and its IP pools. If he receives a decrypted packet when it knows that it must have been encrypted, it will drop the package immediately and a flag a syslog something as "received the decrypted packet when it should have been."

• bug in iOS? startup-config + command access-list + an invalid entry detected

  I posted this yesterday in the newsgroup usenet comp.dcom.sys.cisco and received no nibbles. If I did something incredibly stupid, please do not hesitate to advise.

  IOS (TM) C820 software (C820-K9OSY6-M), Version 12.2 (8) T5, RELEASE

  SOFTWARE (fc1)

  I'm looking to use a host named in a more extended access list. The

  script I copy startup-config contains the following entries:

  ! the 2 following lines appear at the top of the script

  123.123.123.123 IP name-server 123.123.123.124

  IP domain-lookup

  ! the following line appears at the bottom of the script

  120 allow host passports - 01.mx.aol.com one ip access-list

  When I reboot the router, I saw the following message:

  Translation of "passports - 01.mx.aol.com"... the domain server (255.255.255.255)

  120 allow host passports - 01.mx.aol.com one ip access-list

  Invalid entry % detected at ' ^' marker.

  It seems as if the entrance to the server name of the router is not processed

  prior to the access list. I can not even check with

  router02 access lists 120 #sh

  makes the access list entry * not * exist.

  But when I manually type the entry in the router I see the

  and I can confirm its creation:

  Extend the 120 IP access list

  allow the host ip 64.12.137.89 one

  I have to do something incredibly stupid. If necessary I can post the whole startup-config, although it is quite long. (I don't know if the same label/common sense if apply here as apply to newsgroups usenet. i.e. post us actual ip addresses in our configs or must they be edited?)

  Any help is very appreciated.

• access lists

  I have a question... or two... :) on access lists.

  My current access list looks like the following:

  access-list acl_outbound allow icmp a whole

  acl_outbound list of access allowed tcp 192.168.50.0 255.255.255.0 any eq 80

  acl_outbound list of access allowed tcp 192.168.50.0 255.255.255.0 any eq 21

  acl_outbound list of access allowed tcp 192.168.50.0 255.255.255.0 any eq 443

  access-list acl_inbound allow icmp a whole

  outside_cryptomap_9 192.168.50.0 ip access list allow 255.255.255.0 host Bluff_Outside

  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.

• card crypto access lists / problem if more than one entry?

  Access list for IPSec enabled traffic.

  I've been recently setting up a VPN between two sites and I came across the following problem:

  I wanted to install a VPN that only 2 posts from site A to site B, a class C network

  So I created a list of access as follows:

  access-list 101 permit IP 192.168.0.1 host 192.168.1.0 0.0.0.255

  access-list 101 permit IP 192.168.0.2 host 192.168.1.0 0.0.0.255

  When I applied the access list above to map (match address 101) encryption, I quickly realized that only the first host (192.168.0.1) was successfully encrypted beeing while the other could not. I've been geeting on ipsec debugging errors saying that traffic to 192.168.0.2 denyed by the access list.

  When I changed the access list above with the following

  access-list 101 permit IP 192.168.0.1 0.0.0.255 192.168.1.0 0.0.0.255

  two items of work could successfully encrypted through IPSec tunnel.

  To look further into it, I realized that only the first entry of the IPsec access list has been really tested for the corresponding traffic!

  Is this a normal behavior or a known Bug? No work around for this problem?

  Kind regards.

  If you have ipsec-manual crypto map in crypto ACL, you can specify that an ACE. Check 12.2 docs:

  Access lists for labelled as ipsec-manual crypto map entries are limited to a single permit entry and the following entries are ignored. In other words, the security associations established by this particular entry card crypto are only for a single data stream. To be able to support several manually created security for different types of traffic associations, define multiple crypto access lists and then apply each a separate entrance card crypto ipsec-manual. Each access list should include a statement to define which traffic to protect.

• Routing VPN access list

  Hello

  I have a PIX 525 to my main site and a 1721 router at a remote location. I used the PDM and the SDM to configure site-to-site IPSec VPN connection. In my private network, I use 10.1.0.0/16 for the main site and 10.x.0.0/16 (where x = 2-47) to remote sites.

  The remote site with the VPN connection uses 10.19.0.0/16. When I originally created this VPN, I configured the traffic to flow from the remote site to 10.1.0.0/16 only. This means that the remote site cannot speak to any other remote sites, just the main site.

  I need to modify the access list to solve this problem. The relevant part of the remote site access list is now:

  access-list 103 allow ip 10.1.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  access-list 103 deny ip 10.19.0.0 0.0.255.255 everything

  Can I change the subnet mask in the first line and put the second line first?

  access-list 103 deny ip 10.19.0.0 0.0.255.255 everything

  access-list 103 allow ip 10.0.0.0 0.255.255.255 10.19.0.0 0.0.255.255

  Or should I let the deny at the end statement, and add a line for each of the other remote sites:

  access-list 103 allow ip 10.1.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  access-list 103 allow ip 10.2.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  access-list 103 allow ip 10.3.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  access-list 103 allow ip 10.4.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  ... (others)

  access-list 103 deny ip 10.19.0.0 0.0.255.255 everything

  Thank you.

  Help the additional configuration information that you have posted. There are still a few things which I hope could be clarified. It seems that you have 46 remote sites and only is connected via a VPN. How have the other connectivity? It is all over the links within your private network? Is there than any NAT involved in these other connections?

  In my previous answer, I assumed that there will be multiple VPN connections, revealing your additional information is not the case. So my comment about limitations in PIX for talk of talks is true but not applicable to your situation.

  Other remote sites are also coming via the VPN? If yes access list 100 which the 1721 uses to identify the IPSec traffic (and that was not in your posted material) will probably have to be changed.

  According to access list 103 is concerned, I guess that the deny ip 10.19.0.0 0.0.255.255 is an anti-spoofing measure? If so, I would probably advocate put it as the first entry in the access list. What about if you want to use ip 10.0.0.0 allow 0.255.255.255 10.19.0.0 0.0.255.255 or a series of individual licenses, according to me, a point to consider is that allowed 10.0.0.0 0.255.255.255 will allow any space of 10 addresses. It seems that you use 1 to 47. What happens if something came through 10.122.x.x? I suggest a compromise approach. You can use this:

  IP 10.0.0.0 allow 0.31.255.255 10.19.0.0 0.0.255.255

  ip licensing 10.32.0.0 0.15.255.255 10.19.0.0 0.0.255.255

  This would allow 1 to 47 but not others.

  the golden rule of the acl, is that it works in order, from top to bottom. with the line number, you can precisely insert the new entry of acl or note everywhere where you want.

  for example, imagine you have a 200-entry acl, and now you want to allow one host before the other refuse registration. of course you don't want to interrupt the network by UN-apply and reapply the entire acl. in this case, the line number to save life.

• How can I configure Time Capsule 3 to and Motorola NVG589 to access the Time Capsule backup drive?

I think I am following the steps in Airport utility, but once installation is complete I can find is no longer the time Capsule.

  I want to configure my Time Capsule 3 to extend the network

  The time Capsule cannot "extend" the network Uverse using a wireless connection, if that's maybe what you're trying to do. The time Capsule can only wireless "extend" the signal of another router from Apple.

  The Capsule can be configured to extend the network to Uverse if it is connected permanently... anytime... to the Uverse router using a connection through wired Ethernet cable.

  Help!

  Try restarting/resetting the router.

  Try a reboot.

  Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

  Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in system preferences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

  Isolate a problem by using a different user account

  If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.
