• 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.

• Cisco ACS and Pix Firewall

  I have configured the aaa authentication in the pix firewall to see the ACS RADIUS Server for verification of the user. If the ACS server becomes unavailable, then I could not connet the pix firewall.

  In the router, I have the configuration option

  AAA authentication login default group Ganymede + local

  that tells the router first looking for a radius server and if is not available connect through the local database.

  Is there an option in the Cisco pix firewall to connect using local information if ACS is not available?

  Thanks in advance

  Hello

  PIX back up method to entered the unit in the event of server failure aaa works on 6.3.4 code and above. In the codes plus late 6.3.4 If the RADIUS server fails it is impossible to get in unless password recovery. "However if we have not configured for console aaa authentication than user name: pix and password: cisco" works by default.

• Active FTP problem between Checkpoint and Cisco PIX

  Hello

  I am facing a strange problem.

  Many of our customers have achieved a Checkpoint FW-1/VPN-1 4.1 SP6 (the last before NG). When they try to connect to an FTP server that is located behind a Cisco PIX firewall, they are not able to transfer data: the connection is established, the authentication to follow, but at the stage of the 'LIST' the connection 'freeze' and the user must close the FTP client.

  Users are facing this problem ONLY in Active mode: passive mode works very well. Turn passive mode FTP client isn't acceptable workaround for most of my clients.

  The problem seems to be related only to the firewall Cisco PIX and active FTP.

  Please, what is someone encountered the same problem?

  Could someone give me any help?

  Thank you in advance.

  Paolo

  Yes it is a (global) problem, even with the last checkpoint firewalls. What happens with Active FTP, it's that each command (get, list, etc.) causes another log on the client (source port) to the server on port 21. If you run netstat from the customer you can check this for yourself.

  What normally happens, with HTTP, FTP, telnet, which have are, it's that the client makes a connection to port 21, 23 etc then returns with a port source such as 1936, 1980, 3000, etc..

  Connect problem with statefull firewall is they do not allow multiple sessions control port number on a destination, as well as a source port can be bound to a destination port, in this case, 21 for FTP. I Don t see it changed, an extreme security risk any time soon, since it s, someone else might be hopping session and block this type of traffic, it's what the stateful firewall are all about and FTP servers are problably the machines more pirated on the planet.

  You´ve mentioned the workaround solution, unfortunately that s the only way, change your passive customers, I think that Unix/Linux customers have a problem with this, change your FTP server can also help, there are multiple servers that can be configured to disable Active FTP, I wouldn know exactly, I only network & firewall... maybe someone else can move on this...

• Unable to ssh on alternative port

  Mini Mac OS X Server 10.11.6, CommuniGate Pro, no and almost no other stock OS X Server services.

  The server owner recently found on a network that has blocked ports for VPN and SSH connections, so we try to set up the server to allow a SSH tunnel through SOCKS proxy port 443, which is almost always open. (We have no plans on execution of web services via this port on this area.)

  Research indicates that this should be a two-step process: 1) Edit /Library/Server/Web/Config/Proxy/apache_serviceproxy.conf to remove the web listening on ports 80 and 443 ports; (2) edit/etc/ssh/ssh_config for add a SSH listener on port 443. then restart.

  After that, HTTP services are off on 80 and 443, but I can't connect to SSH on port 443. Works very well over 22 yet. Nmapping the server indicates that there is nothing open on port 443. Is there anything else I need to do for this open?

  A user on the stack Exchange responded to this question. Works a charm.

• 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

  NAT is your problem, IE.

  NAT (inside) 0-list of access inside_outbound_nat0_acl
  NAT (inside) 0 0.0.0.0 0.0.0.0 0 0

  presumanly first NAT is fot your good VPN that acl looks a little funny, what exactly are you doing with that?

  The second NAT is the real problem but for outgoing internet access - the NAT statement, you said not NAT one of your addresses 10.10.10.x which is a problem as 10.x.x.x address is not routable on the Internet.

  You must change this setting IE. -

  (1) remove the second NAT statement IE. "no nat (inside) 0 0.0.0.0 0.0.0.0.

  (2) add a new statement of NAT - ' nat (inside) 1 0.0.0.0 0.0.0.0.

  (3) add a corresponding statement global - global (outside) 1 interface.

  This will be PAT all your 10.10.10.x to external IP addresses.

  Apologies, but these are some CLI commands that I don't use PDM.

• PIX 515E and Telnet to port 25

  When I telnet (in or out) on a mail server (using port 25) the answer is:

  220-*******************

  and all orders come back as "invalid command."

  When I put the old (no - pix) firewall, this does not happen (the responses are complete and commands work fine.)

  A lot of email is coming and going, but some mail servers cannot send email.

  This is common for misconfiguration and where should I look?

  Thank you

  Delete the fixup protocol smtp 25!

  command to run:

  No fixup not protocol smtp

  Details about this:

  The order fixup protocol smtp active the function of guard of mail, which allows only mail servers receive the RFC 821, section 4.5.1 of the orders of HELO, MAIL, RCPT, DATA, RSET, NOOP, and QUIT. All other commands are translated into x which are refused by the internal server. The result is a message such as "500 unknown command: 'XXX'.» Incomplete orders are ignored.

  Note during a SMTP session interactive, different SMTP security rules may reject or hang with your Telnet session. These rules include the following: SMTP commands must be at least four characters; must end with the return cart and jump; of line and must wait for a response before issuing the next reply.

  From PIX Firewall software Version 5.1 and higher, the fixup protocol smtp command changes the characters of the SMTP banner asterisks except for the "2", "0", "0" characters. Return (CR) and linefeed (LF) characters are ignored.

  PIX Firewall software Version 4.4, all the characters in the SMTP banner are converted to asterisks.

• Access PIX using SSH when connected remotely with VPN client

  Hello

  I think that this should be a fairly simple for someone to sort for me - I'm new to PIX configuration If Yes please excuse my stupidity!

  I changed the config on our PIX to allow only access via SSH (rather than via telnet as it was previously configured)

  Now, everything works fine when I'm in the office - I can connect to the PIX using SSH without any problem.

  However, if I work from home and connect to the office using my VPN client (IPSEC tunnel ends on the PIX firewall itself) I find that I can not connect to the PIX.

  I have configured the PIX to access ssh on the office LAN subnet and the client pool of IP addresses used for VPN connections by using the following commands:

  SSH 172.64.10.0 255.255.255.0 inside

  SSH 192.28.161.0 255.255.255.0 inside

  where the 1st line is reference to the office's LAN, which works very well, and the 2nd line denotes the IP address pool configured on the PIX for VPN access.

  Can someone tell me how to fix this? I have the feeling that its something pressing!

  Thank you

  Hello

  Can someone help me on how to access the CLI mode in cisco sf 302 - 08 p 8-port 10/100 Managed switch. I treid the each method they mentioned in the administration guide. I am not able to enter the command debug mode and comand menu after resetting the default password. Once connected, sound directly to guide me to switch main menu.

  Hello FAL, Mark,.

  Thank you for your participation in the community of support to small businesses. My name is Nico Muselle of Cisco Sofia HWC.

  To access the CLI, you must make sure that the version of the firmware on your switch is at least 1.1.0.73 or preferably higher. Then activate telnet or ssh on the switch and opening of these sessions or a console session you will see that you are in CLI mode. You can return to the console to function menu using the menucommand.

  I hope that answers your questions!
