• Link inside the declaration of nat in outermost interface ERROR

  Hi all

  I'm having a problem with my PIX501 w / "Cisco PIX Firewall Version 6.3 (4)", when ordering I get this caveat, is that normal? because it works perfectly fine in version 7.2 (2)...

  THE ERROR:

  PIX1 (config) # nat (outside) 1 222.127.244.52 255.255.255.252

  WARNING: Link inside the nat in outermost interface declaration.

  WARNING: Keyword 'outside' is probably missing.

  REFERENCE:

  # Sh nameif PIX1

  ethernet0 nameif outside security0

  nameif ethernet1 inside the security100

  In addition,

  Here is information on the 'outside' of the order PIX 6.3 setting

  outdoors

  If this interface is on a lower security interface that you identify by the corresponding overall statement, you must enter on the outside. This feature is called outside NAT or bidirectional NAT. Note from firewall PIX 6.3.2 source translation is performed before the translation of destination. For this reason, if the political source NAT allows the connection, the xlate will create, even if the traffic is denied by the policy of destination.

• DMZ web server-> inside the database server

  Suppose that a network topology looks like this:

  A PIX with 3 interfaces:

  interface (private public static IP 10.10.10.1)

  interface (public static IP of 69.110.38.35)

  interface (static IP private address of the 30.30.30.1)

  --------------------------------------------

  The internal network has a {server} with the IP address of 10.10.10.2.

  The DMZ has a {web server} with the IP address of 30.30.30.2.

  I will welcome external guests (outside) access to the web server (30.30.30.2) via port 80.

  This web server access turn the database server (10.10.10.2).

  Assume that all other commands are issued. Then, I'll create an access list that allows server WWW DMZ to communicate with inside the database server.

  access-list dmz-to-inside permit tcp host 30.30.30.2 host 10.10.10.2 eq 1521

  Should I publish the following, too:

  (1) access-list dmz permit tcp host 30.30.30.2 no matter what 80 eq

  (2) access-group in interface dmz dmz

  (3) static (inside the dmz) 10.10.10.0 10.10.10.0 netmask 255.255.255.0

  xlate clear 4)

  If so, what each of them do?

  Thank you for helping.

  1. Yes, the static statement "10.10.10.0 static (inside, dmz) 10.10.10.0 netmask 255.255.255.0" will disable NAT. Although it is not necessary to disable nat, however, it saves money and simple to manage. the reason for this is the traffic between the dmz and inside is private, there is therefore not necessary to apply the public ip address.

  2 pix receives the package intended to 30.30.30.2 10.10.10.2. PIX examines the static statement and based on the static above statement, pix will not nat package (i.e. pix will leave the soruce address be) and send it to 30.30.30.2 via the interface of the demilitarized zone.

  for example

  original package - source 10.10.10.2, destination 30.30.30.2

  After pix - source 10.10.10.2, destination 30.30.30.2

  3. the "Clear xlate" command must be issued whenever the nat/global or static has been added/deleted/modified. This command is to force the pix to clear the existing ip translation.

  for example, before you add the command "static 1.1.1.1 (indoor, outdoor) 192.168.1.100 netmask 255.255.255.255", the pix may already have an ip 192.168.1.100 translation (it might come from the nat/global). now, after you apply the static command, the pix will keep the existing translation for a certain period time. 'clear xlate' is needed to erase the old translation and so to activate the new static statement.

• Can not handle the ASA inside the interface of Site to Site VPN

  Hi all

  I was deploying new site to site between ASA 8.0 (HQ) and ASA 8.4 (branch). Everything works fine but I have a problem on the ASA-reach remote that I can't manage branch ASA with inside the interface IP address.

  Thanks in advance

  Do not know what 8.4 version you use, but it is broken in the 8.4 (2), I stumbled upon the upgrade from same problem. SSH and ASDM will not connect through a VPN L2L interface inside. This worked well in 8.4 (1).

• WRT54GL cannot transmit from inside the LAN port?

  Hello

  I have a Server servers running several (HTTP, SVN, FTP,...) inside my network.

  I used to have a SMC router in the past, and of course I had to use port forwarding.

  This is why I realized that when we "talk" to the server, I can 'talk' to the router that will forward requests to the right compurer, based on the NAT table. If, for example, that if I move the SVN server, I don't have to change the path to the repository, change the NAT entry is OK in this case.

  If this is not understandable, here 's another report.

  However, I discovered that even if my new WRT54GL seems to be much more advanced, it cannot do this. Requests made to the router from within the local network are not transferred to the right place.

  Is there a way to accomplish what we need, or at least a road map? It's sad that the SMC products otherwise is not very reliable can do...

  Kind regards

  Matej

  Well, I have it solved.

  I tried to convey the SVN, HTTP, FTP, and SSH.

  However, it was not working when the server IP assigned by DHCP.

  When I set up (the server within the LAN) to use the static IP address, not only that port forwarding began to make sense, but I have seen web pages by typing my public IP address in the browser on a computer inside the LAN.

  What surprised me, is that it only worked when the server had assigned auto private IP address. I know that these addresses change so it would not very long work, but it did not work even before that t has changed...

• Inside Source NAT from the remote host and VPN from Site to Site

  Hi all

  I was in charge of the construction of a vpn tunnel with a firewall PIX of our business partner company and ASA of the other company of the firewall.  Traffic will be A partner business users will access my company Citrix server.  I want to source-pat the user traffic partner company to PIX of my business within the interface to its entry in my LAN to access my company Citrix server.  The partner company will be PAT'ing their traffic from users to a single ip address - Let's say for discussion end is 65.99.100.101.  There is the site to site vpn configuration, and configure nat be performed to allow this traffic in accordance with the above provisions.

  I'm more concerned about the accuracy of the configuration of the domain encryption because NAT is involved in this whole upward.  My goal is to NAT (of the other company company a) ip address to a routable ip address in my company network.

  The fundamental question here is should I include the ip address of real source (65.99.100.101) of the company the user or IP natted (10.200.11.9) in the field of encryption.

  In other words should the encryption field looks like this

  OPTION A.

  permit ip host 10.200.11.103 65.99.100.101

  OR

  OPTION B

  permit ip host 10.200.11.103 10.200.11.9

  I'm inclined to think it should look like OPTION A.  Here's the part of MY complete SOCIETY of the VPN configuration.  I've also attached a diagram illustrating this topology.

  Config looks good - just as domestic mine to my local network. The only thing I can think is that you may have entered commands in the wrong order - which means, you could have isakmp or encryption before the config map was complete. Write memory, then reloading the pix is a way to reset everything. If you do not want downtime:

  mymap outside crypto map interface

  ISAKMP allows outside

  Enter these two commands should be enough to reset the ipsec and isakmp.

  Please give advise me how should I do.

  Hello

  (1) in the direction of LAN, they can access HQ LAN & resource, but cannot access the internet. I did not configure NAT on the router PH

  Answer:

  You must configure the NAT and crossed to the ASA HQ so that the VPN branch router provides LAN and u-Turn, access to Internet of the SAA.  You must first seup NAT for the branch on the SAA router subnet, then you must type the command:

  permit same-security-traffic intra-interface

  Here's a great example for VPN client hairpining.

  (2) can I access internet BRANCH LAN via HQ LAN INTERNET. Where can I access the Internet of general management of the LAN of the PH router directly while access to the VPN to the local network of HQ?

  (3) in the Site of the Directorate, phone hard cannot work but phone on PC can call to Headquarters. Hard IP phone are same in remote network (172.16.1.0/24 ). What's the problem? How can I configure separately?

  You must change your subnet VLANS to be different from the subnet HQ voice phone IP VOice VLAn, it should be fine.
