• VPN 3.6.3 and Pix 515 6.2connection problems.

  We have improved our image pix at 6.2, but unfortunately cannot get the 3.6.3 client to connect. The message we get is "unable to establish a connection to the security gateway." We don't have a problem connecting with a client 3.2 or 3.5, however. Someone at - it a similar problem?

  Hello

  VPN Client 3.6 always supports DES/MD5; However, support for SHA/DES is no longer available.

  http://www.Cisco.com/univercd/CC/TD/doc/product/VPN/client/3_6/361_clnt.htm#xtocid18

  If the proposal is not configured for DES/SHA and you are still having problems connecting, then after the isakmp and ipsec debugging of the pix and the client logs and we can take a look to see what is happening.

• PIX 515 and software version 6.3 (4)

  We have a PIX 515 (not 515E). Currently, we are running software version 6.2 (2). I was wondering if we can improve the software to version 6.3 (3) or 6.3 (4), or do we need to replace the hardware with PIX 515E?

  Also what should I do on my current PDM version 2.0 (2) if it is possible to upgrade the PIX to a 6.3 version?

  Thank you.

  You can run on the Pix515 6.34. It takes at least 16 MB of flash and 32 MB of RAM.

  If you use PDM, you will need to be updated also.

• How to open a port and limit the range of addresses that use it on PIX 515?

  I have a Pix 515 v6.3 and a new piece of software that I'm getting soon need aura 5080 open port for incoming & outgoing HTTP traffic. The server will be in my DMZ to 10.0.0.1

  I would like to restrict inbound access to this port so that it can be used in 4 specific IP adderess foreign xxx.xxx.xxx.24 through xxx.xxx.xxx.27 and also, if possible, limit the outbound destination using this port to a single specific foreign IP address xxx.xxx.xxx.30.

  Could you please tell me the best way to do it.

  Thank you in advance for a relative novice to PIX.

  PIX (config) # access list acl-outside permit tcp host xxx.xxx.xxx.24 host MyWWWPublicIP eq 5080

• MM, pix 515 and mac filtering

  I have an application called MeetingMaker, located at the back of my pix 515 that is used off site by 5 users. Since accessing this program on the internet, and users can have dynamic addresses, it is possible to filter by mac address somehow to allow access through the firewall to the app? Thank you.

  MAC addresses not browse the limits of layer 3. In others, your MAC address of clients cannot be seen or known once the traffic passes through the default router for that subnet. So the answer to your question is 'no '.

  You can use AAA to handle this. How your clients connect to the server? (port/application)? If its HTTP/S, the Pix can check this name of user and password before allowing access. If it is a part on request/port, you can still use authentication by requiring them to connect to the web server out there first. This will cause the Pix to authenticate by using the challenge of browser, and the Pix can be configured to allow connections to the hosts authentiated.

• PDM with PIX 515 does not work

  I just upgraded our PIX 515 of 6.1 to 6.2. I also added support FOR and loaded the version 2.1 of the PDM. I am trying to browse the MDP, but I can't. What Miss me?

  Hello

  have you added the following lines to your config file and have you used HTTPS to access the pix (http is not taken in charge, only https)?

  Enable http server

  http A.B.C.D 255.255.255.255 inside

  A.B.C.D is the ip address of the host from which you are trying to reach the pix with the pdm.

  If you're still having problems after the addition of these two lines, you might have a look at this page:

• Limit the number of users for a pix 515 uauth

  I have a PIX 515 authenticate and authorize against a Cisco Secure ACS server for outbound internet connections (using the web prompt). For the purposes of scale, I need to know the maximum number of sessions competitor for these types of users. I know there is a limit of 16 reviews on simultaneous approval process (the process of logging in first), but once they are connected, is there a limit?

  Once connected, the number of connections is limited by the number of concurrent connections that can handle a PIX. For example, the PIX 515 E can handle a maximum of 130 000 concurrent connections.

• Cisco Pix 515 VPN problems

  Hi all

  Here's my problem, I have 2 PIX 515 firewall...

  I'm trying to implement a VPN site-to site between 2 of our websites...

  Two of these firewalls currently run another site to site VPN so I know who works...

  I can't do the second site to the site to launch the VPN... when looking on the syslogs I get refused packages...

  Protected networks are:

  172.16.48.0/24 and 172.16.4.0/22

  If I try to ping from the Cisco (172.16.48.4) to 172.16.4.5, I get the following syslog:

  2 sep 02 2008 08:59:47 106001 172.16.48.4 172.16.4.5 incoming TCP connection doesn't deny from 172.16.48.4/1231 to 172.16.4.5/135 SYN flags on the interface inside

  It seems that the tunnel is trying to initiate, but something is blocking the internal traffic to penetrate through the VPN.

  Don't know what that might be, the other VPN are working properly.

  Any help would be great...

  I enclose a copy of one of the configs...

  Let me know if you need another...

  no road inside 172.16.4.0 255.255.252.0 172.16.48.1 1

  Remove this path should you get. Please rate if it does. Similarly, if you have a road similar to the other end, it should be deleted as well.

• PIX 515 DMZ problem

  Hello

  We have some difficulty in moving traffic in and out of a Cisco PIx 515 firewall. We use it with two demilitarized. The first DMZ has a mail in her Server (before end mail server) that communicates with a different mail server (back end mail server) inside, it is called DMZ1. The second DMZ (DMZ2) has some users who are expected to pass through the firewall to the outside and use the internet and must have access to the e-mail DMZ1 server. Inside users must be able to use the Internet and can access DMZ1. Here's the important part of our Setup.

  What we were doing, we can correctly access from inside, inside users to access internet permit to join the DMZ1 e-mail server and the mail in DMZ1 server the inside. Our problem is that we are unable to browse the internet on the DMZ1 Messaging server if we put DMZ1 as gateway ip address on that server and the address ip of the DNS of the ISP is propely located on the same machine. Also, we could not do DMZ2 users browse the internet, although we allowed the www Protocol in the fromOut access list. One last question, can we do the DMZ2 a DHCP server on the interface on the PIX and do distribute ip addresses to users on that subnet only? Thanks for any help in advance.

• Upgrade from PIX 515

  Hi all

  My company needs upgrade its PIX 515 to have the function VPN 3DES for remote site connection. So I just need to buy a license of 3DES for the PIX functionality? and can I also upgrade the IOS 6.1 so that I can use PDM to config the PIX? And I also need to upgrade the memory in the PIX?

  Thank you very much!

  Best regards

  Yes to the first question.

  Better 6.2 and pdm 2.1 I think.

  How much memory do you have? Reach

  There is memory for pix 6.2 requirements

  Good luck!

• A question about the old Pix 515

  Hi Experts.

  My client needs additional interfaces of FE and do not want to migrate the chassis 515E.

  Can the data sheet of the former 515 Pix no longer available due to the declaration of the EOS, you please confirm that the Pix 515 supports 1FE - PIX and PIX - 4FE cards before ordering one of them?

  Thank you

  The 515 supports 4 interface cards. Make sure they are running a UR pix license if - 515R takes only supported 3 interfaces.

• DNS traffic blocked after PAT - PIX 515

  I have PIX 515 with 3 named NIC (internal, external, dmz)

  I have 2 servers (Exchange and Windows 2000 with SMTP) in the demilitarized zone.

  I currently have a static command pointing to doamin for exchange Server IP address in the DMZ.

  I wanted to PAT on the IP address of the e-mail domain so that the configuration will look like as follows.

  The IP field will be used for the global IP

  all pop3 for global ip traffic will go to Exchange

  all www for the global IP traffic will go to Exchange

  all smtp for global ip traffic will go to the Windows 2000-based SMTP relay (SMTP relay is configured to send the e-mail received in exchange Server)

  I hosted DNS udp and tcp traffic to the servers.

  before pat, the server can use DNS to resolve IP domain e-mail and send mail to the Internet.

  As soon as I PAT the Internet e-mail delivery stops.

  When I did an NSLOOKUP command returns an error indicating that the DNS server cannot be resloved.

  The servere DNS used by these 2 servers are servers DNS of ISP.

  Is there any concern when you PAT.

  Thank you

  Hello

  I found the problem:

  for now, your dmz servers can go to the internet with pop3, smtp, and www. Only for these protocols is a (static) translation to provide in the config file.

  You will need to will provide you a translation for other protocols (for example, dns) also. This can be accomplished with one of the following two things:

  create a nat - pair overall for the DMZ for outdoor

  NAT (dmz) 1 0.0.0.0 0.0.0.0

  Global (outside) 1 200.100.100.168 (already exists)

  create a static translation for each of the other protocols (next to pop3, smtp, www), you want to pass from the dmz to the internet (you already did that for www, pop3 and smtp).

  Kind regards
