• My 506th Pix configuration

  How can I set up the following scenario. My Pix is separate internal and external network. For outgoing, I will not allow that the associated HTTP traffic. There will be no incoming traffic. For simplicity, I use ver3 PDM to configure my 506th Pix. Should be easy to set up, I thought.

  On my access rules, I allowed http and https on the inside and outside interfaces nameserver. Translation rules, I have set up NAT using a real IP on the external interface range. I have not used just in case PAT H323.

  However, the configuration above does not work. I can't any http my internal network traffic. What Miss me?

  Thanks for your help,

  FTM

  It would seem that you define the rules that indicate the source AND destination must be the same:

  inside_access_in list of access permit udp any eq field any eq field

  inside_access_in list access permit udp any eq ntp ntp any eq

  inside_access_in list access permit udp any eq name server any eq nameserver

  inside_access_in tcp allowed access list any domain eq any eq field

  inside_access_in tcp allowed access list all eq www all eq www

  inside_access_in list of permitted tcp access any https eq all https eq

  You need change that, because the source is probably going to be 1024 or greater. Try something like this:

  inside_access_in list of access permit udp any any eq field

  inside_access_in list of access permit udp any any eq ntp

  inside_access_in list access permit udp any any eq name server

  inside_access_in list access permit tcp any any eq field

  inside_access_in list access permit tcp any any eq www

  inside_access_in tcp allowed access list everything all https eq

  inside_access_in access to the interface inside group

  Having said that allow any source ip/source port access to any IP destination as long as it is for www, dns, ssl, etc...

  Your acl_web access list is not used, because it is not assigned to an interface. Remember that each interface can have only one acl.

  Also, you said that you do not PAT...

  Global (outside) 1 xxx.xxx.YYY.54 - xxx.xxx.YYY.55 netmask 255.255.255.0

  Global 1 xxx.xxx.YYY.53 (outside)

  NAT (inside) 1 0.0.0.0 0.0.0.0 0 0

  This tells the firewall to use the range xxx.xxx.YYY.54 - xxx.xxx.YYY.55 for the assignment of an address, but when he runs, start PAT'ng with xxx.xxx.YYY.53...

  hope this helps

• PIX configuration as a blocking device w / GANYMEDE + authentication

  Hello

  I have a PIX running version 6.3 (1). The PIX is configured to use a Server 3.1 CSACS AAA authentication and authorization more GANYMEDE +. The sensor is 2.0000 Sig46 running.

  Before adding AAA for the PIX, the sensor has been able to connect and set up to Shun correctly. Since the addition of the configuration of the AAA for the PIX, I was unable to get the sensor to connect to the PIX for fleeing.

  I created a login and password with rights admin for the IDS sensor connect to create leaks. I could authenticate and build manually fled via a Telnet and SSH connection using this connection. I tried to remove and re-add lock several times.

  When I configure the PIX as a blocking Telnet device, I see the State of the Net as "initializing" device when you look at the statistics of the IDM. When I configure the PIX as a SSH blocking device-, I consider the State as "inactive".

  Please let me know if you have any suggestions - if not I guess I will open a case with TAC. Thanks in advance for the help!

  Kind regards

  Chad

  Make sure the PIX is in the list of allowed hosts. From the cli, type

  end of config

  SSH - key host (ip interface pix)

  Check that you have associated the pix of polarity

  logical device. The logical device record contains the username,

  password password and activate. Using IDM, it is selected in a

  drop-down list on the page of blocking devices.

• PIX configuration with several requests from NAT

  Hello

  I have PIX running version 7.1 (2). I use "nat 0" for all outgoing traffic to bypass NAT I have 5 different networks without going through the NAT. PIX device but I want to apply NAT just for a new network without affecting the rest of the traffic. I want that this new network to translate a specific routable IP.

  What is a possible solution? I am trying to aplly NAT on only 10.1.1.0 255.255.255.0 network.

  Global (OUTSIDE) 1 192.168.1.2

  NAT (INSIDE) 1 10.1.1.0 255.255.255.0

  NAT (INSIDE) 0 0.0.0.0 0.0.0.0

  Thank you

  Ercan

  It should work. I assumed the 192.168.1.2 is that an IP address belongs to the same interface/Public external IP range (assigned by ISP).

  Your "nat (inside) 1' and ' global (outside) 1' pair correctly will allow hosts on 10.1.1.0/24 turn off using the unique IP address and ignore the NAT 0.»»

  First off I would say don't not cut and paste your config PIX here, or at the x.x.x.x at least on your external IP address.

  The PIX does not support PPTP thru PAT (nat/global). PPTP uses the Protocol IP 47 (GRE), and the PIX cannot PAT these cause there is no TCP/UDP port number to use.

  PIX 6.3 code it will however support, but it won't be available until the beginning of next year. At the moment the only way to circumvent your situation is to define a one-to-one NAT translation for this internal host. Something like:

  > static (inside, outside) 217.215.220.222 194.132.183.10 netmask 255.255.255.255 0 0

  will do for you, providing you 217.215.220.222 routed and available. I would also change

  > acl_outside of access list allow accord a

  TO

  > acl_outside gre 194.71.189.109 allowed access list host 217.215.220.222

  It's a little safer.

• 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

  Neil

• PIX with H & S VPN DMZ hosting web server to the hub

  Ok

  Heres a problem which I think would be quite common for these even remotely conscious of security. Unfortunately, my knowledge of the PIX (as well as other Cisco devices) is still in phase of 'growth '.

  So, here's the problem. I have a WAN put in place with PIXen and SonicWalls, we are set up in a design essentially Hub and Spoke (fine ok so it is partially meshed). We recently decided to pull the trigger on getting a 'real' web site and everything went relatively well that getting up and rolling. (even with my notice of 3 days/deadline), but here's the problem: I set up the web server on the DMZ to the hub pix, and I figured out (the easy part) how to set things so in the Home Office, people can connect to the web server by using the internal address, but I don't know what to do for people in remote offices with VPN home connections. I tried to define static routes, I tried to add the DMZ to the VPN trigger, I tried to do both of the last things together, and I checked that I have rules allowing traffic to the VPN outside the DMZ on the inside. So, what else can I I get?

  I have no problem by configuring a PIX for all basic ups and VPN even at this stage, I can do most of it through the CLI (even if I still want to do more through the PDM). My biggest stumbling block on the PIX has so far was when I actually involve this pesky DMZ...

  I actually two PIX in my office, two for my network domestic (one for my place in the States and one for my place in the Japan), so if you can help me, I'll be the two problems and do not forget to give a rating of excellent reviews!

  so I guess that leaves me to the place where I scream...

  Help!

  and I humbly await your comments.

  the current pix configuration should look at sth like this,

  I activated traversal of NAT using the PDM, but when I connect with this option, I get the error that the "remote endpoint is NOT behind a NAT device this end is behind a NAT device" and ping fails.

  Hugh, sure you can classify based on the whole conversation, but you don't have to do but be certainly provide assessments.

  To sum up the shrinking global problems, the main objective was to ensure configuration VPN RA on the PIX501 has been corrected.

  1. we have enabled NAT - T on the firewall - even if it wasn't the question, but need it either it should you RA other places - travseral NAT VPN sensitizes the firewall on the other ends NAT devices - here is some good information on NAT - T for reference in the future

  http://www.Microsoft.com/technet/community/columns/cableguy/cg0802.mspx

  2. we fixed the VPN-POOL/28 network as well as the access list and acl to be coherent crypto sheep.

  Here is a link for future reference with many PIX configuration scenarios

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/prod_configuration_examples_list.html

  Finally, your only question remaining, we can say is purely isolated with the customer software vpn and MAC machine.

  You could maybe try a different version of the client in the MAC, or also look at the release notes for the open caveats to avoid cisco cleint managing versions and MAC versions if there are problems.

  But how to activate ID 47 in PIX configuration?

• PAT on PIX vs NAT overload on router

  Better question practice...

  It's better to perform PAT through a NAT overload on a router bastion with a static on the PIX instruction or PAT on the PIX configuration uses a global IP address?

  Other alternatives?

  Example of router *.

  Router configuration

  IP nat FirstPAT 172.16.5.100 pool 172.16.5.100 255.255.255.0

  FirstPAT IP nat source list 10 overload

  access-list 10 permit 10.10.10.0 0.255.255.255

  PIX installation

  static (inside, outside) 10.10.10.0 10.10.10.0 netmask 255.255.255.0

  Example of PIX *.

  Global (Outside) 1 172.16.5.100

  NAT (inside) 1 0 0

  Thanks in advance for all the messages!

  In my opinion, there is no real compelling reasons to go with one idea on the other. Probably, I would lean towards leaving the PIX do NAT, but I could be swayed. The reason is that the PIX has essentially already been NAT (all back on the same address). But again, either should be good.

  A suggestion however if you went with overloading NAT on the router would be to do it with a map of the route as opposed to the example of access list you have. Something like this:

  IP nat FirstPAT 172.16.5.100 pool 172.16.5.100 255.255.255.0

  IP nat source map route nat FirstPAT overload

  route nat allowed 10 map

  access-list 10 permit 10.10.10.0 0.255.255.255

  This creates a NAT entry in the NAT table on the router.

  Good luck.

• PIX 501 VPN

  Hi, I just got my PIX configured based on the clear capability statement, I got one of you this morning. Now, I'm trying to set up the VPN, I looked at the Cisco site (http://cisco.com/en/US/products/hw/vpndevc/ps2030/prod_configuration_examples_list.html#anchor14) but could not understand that we need to follow. Could you please send me the instruction or the link to configure vpn? Also, I don't have the vpn client to test my vpn, how what to do? As you can understand my question, I am new to cisco gear... Thank you.

  Hello

  I'm guessing that you need one of these two virtual private networks.

  -Remote access VPN: where remote allows the Cisco VPN client users to access the resources of the company

  -Site to site VPN: where two systems with IPSEC support establish a VPN tunnel, allowing the internal LAN from different termination points (offices) communicate.

  You can find these two examples on the url you gave.

  If the remote access, I'd watch

  http://Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080702992.shtml

  And then also look at how to set up the split tunneling, then the home user can access the resources of the business AND Internet.

  For the site to site VPN, it depends if your device is a PIX / ASA or a router.

  It will be useful,

  Paulo
