• Allow Cisco VPN Client through the firewall?

  Hello

  How can I allow a cisco VPN client work from the inside of our network to an external IP address?

  We have customers who wish to make use of their Cisco VPN Client companies but our ASA blocks I think?

  Also (sorry to ask) a friend in South America is having the same problem but I am not hink they use Cisco, is there a default port used by the client to Cisco? then I can send this info?

  Thank you

  Generally, the ASA will allow the IPSEC from the inside to outside traffic. This is when you want it came outside and connect to you - this is where it gets creative. You restrict outgoing traffic at all? You deny all ip/tcp/udp outgoing?

  But may depend on if the remote end is compaitable NAT - T, and if they have configured. Another question would be how they allow VPN traffic go?

• How to limit the ICMP on the PIX firewall.

  Guys good day!

  I have a dilemma with regard to limiting ICMP users browsing to other networks such as other demilitarized interns.

  I know that, to allow ICMP to pass through interfaces, you will need to create an ACL such as below:

  access-list DMZACL allow icmp a whole

  Users require this config ping a server on the DMZ, but it is a security risk.

  To minimize, I have a group of objects created in order to identify hosts and networks is allowed to have access to the echo-replies.

  Again, this is a problem since many host who extended pings just to monitor the connectivity server and its application.

  Do you have other ideas guys?

  As to limiting the echo answers on the PIX. As first 5 echo request succeed with 5 echo-replies and the rest would be removed.

  This could be done?

  Thank you

  Chris

  Hello.. I don't think you can do this by using an ACL on the PIX, however, you might be able to stop the ICMP sweeps by activating CODES signatures using the check ip command you... For more information see the link below

  Guidelines of use Cisco Intrusion Detection System (IDS Cisco) provides the following for IP-based systems:

  ? Audit of traffic. The application of signatures will be audited only as part of an active session.

  ? Apply to the verification of an interface.

  ? Supports different auditing policies. Traffic that matches a signature triggers a range of configurable

  actions.

  ? Disables signature verification.

  ? Always turns the shares of a class of signature and allows IDS (information, attack).

  The audit is performed by looking at IP packets to their arrival at an input interface, if a packet triggers

  a signature and the action configured does not have the package, and then the same package may trigger another

  signatures.

  Firewall PIX supports inbound and outbound audit.

  For a complete list signatures of Cisco IDS supported, their wording and whether they are attacking or

  informational messages, see Messages in Log System Cisco PIX Firewall.

  See the User Guide for the Cisco Secure Intrusion Detection System Version 2.2.1 for more information

  on each signature. You can view the? NSDB and Signatures? Chapter of this guide at the following

• Remote Desktop from Win7 not passing is not by the cisco pix firewall, but xp can.

  our company lan remote office work like this:

  Win7 for win7 ok

  Win7 for xp ok

  XP and win7 ok

  XP to xp ok

  Which leads me to believe that all the parameters and features of firewall and rdp pc work fine.

  our remote users connect via the cisco through our cisco pix vpn client business and Remote Desktop works like this:

  inside lan xp ouside xp OK

  inside lan xp ouside win7 OK

  Here's the problem:

  inside to outside win7 win7 ==> does NOT connect to (rdp that is)

  inside win7 for xp outdoor ==> does NOT connect to (rdp that is)

  External clients CAN of course accept rdp because it works when initiated by the xp machine.

  ONLY win7 machines cannot use rdp through the cisco firewall

  Yes, the dns resolves properly throughout.

  Yes, remote desktop IS active (Yes, some may ask me that...)

  Ping is not allowed through the firewall, so it makes no difference.

  the result is the same whether the win7 firewall is on or off.

  all the necessary pc firewall settings are good, as demonstrated in the first part.

  Why can you connect the NO Win7?  but the XP machines?

  Any help is appreciated, thanks.

  I think that there are some weird setting in Win7 that didn't exist in winxp.

• administration remotely through pix

  I have a remote network that got pix and hundreds of users.

  now I wanted to remote admin all users in this remote from our head office. My understanding is apart from allowing my machine to get through the firewall remotely, I call a static command as well.

  in this regard, since I got hepatitis has hundreds of machines to be remote admin, is there a way I can do in a singele static command to cover the range. from now on, I'm doing a static command line 1 by the remote machine.

  Thank you.

  Hello!

  After going through the question. I understand that you have head office and a branch office. you want to be able to access the resources of the Branch Headquarters. The best solution for this kind of situation would be to set up LAN to LAN vpn, this way you will be able to access the remote netowrk of Headquarters and vice versa has securly. Static implementation for all the machine would not be the solution and should be a lot of public to be consumed ip address.

  If you like this solution, you can make by following this document:

• Is it safe to leave netbios D through the firewall?

  I notice that netbios d wants to access the computer through firewall he.

  What is a required protocol?

  NetBios is the protocol used by the Windows file share to discover other computers using the same protocol. Do not allow this through your firewall.

  Even if you don't want to allow access to a remote computer, it must be done via a VPN connection. You should not let any network of ports opened to the Internet unless you really have to. examples where you run a website or, of course, a VPN server.

  If that rather than being a network-level firewall that is a device of protection for your entire network, is instead a software firewall on your Mac and protecting so just as Mac, then you will allows NetBios through so that other computers on your network can make Windows sharing files with you.

• 5324 SSH running but not asking not password and not running through my firewall

  I picked up a Dell Powerconnect 5324 off ebay and wiped the configs, updated the firmware and got it mostly set up for what are my needs but I don't know why good SSH than active and working locally on the same subnet as the ip of the vlan has the following two issues:

• Access list ID # on a PIX firewall

  Is anyone know what of the identifier access list on a pix firewall?

  Standard IOS = 1-99

  Extended IOS is 100-199.

  SW = PIX?

  There is no "limit" by Word to say in the Pix. These limits are in IOS because they define what 'type' of acl, it's IE APPLETALK, IPX, IP etc etc. Pix IP is therefore not necessary for this type of identification.

  access-list 100000000000000; 1 items

  allow line of the access list 1 100000000000000 ip any a (hitcnt = 0)

• Pass through IPSEC on Cisco 857

  Hello people!

  I have gained reciently a Cisco 857 router. I want to do a site-to-site VPN.

  I set up the ATM0.1 with "ip unnumbered" VLAN 1 interface. I have not configured the router to enable NAT or PAT. VLAN 1 is configured with a public Ip of my ISP address. Behind the cisco router, I have a Zywall 5, this device is my VPN gateway. Initially, it works very well with the other soho router but it blocks often, for this reason, I decided to change it for a cisco router.

  My problem now is that the cisco router does not allow the implementation of VPN.

  Need to activate the IPSEC pass-through?, how can I do this?

  Thanks in advance!
