• PIX and NAT - T

  Hi all

  I have a small question. I have a couple of users who use routers to connect by VPN to our pix that authenticates by a RAY for L2TP connections. I enabled the NAT - T on our PIX and they may not always connect. Is there anything I might have missed. I checked most of the posts in this forum do not see anything else, I should have activated.

  Can anyone help?

  Thanks in advance.

  Michael

  A tunnel of Lan-to-Lan of a router in a PIX does not NAT - T, unless there is NAT devices between two end points. If this is the case, you must ensure that both the software both from the end of rehbeh points devices support this capability. An example of a router to tunnel PIX IPSec configuration is available at http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094498.shtml

  Another example that deals with the same configuration with NAT is available at

• PIX SMTP NAT or Port based NAT?

  I have what may seem like a strange question...

  I have a client with a PIX and a SMTP server inside their network. They were using a NAT Port basis via the following command (all IP addresses are changed to protect the innocent):

  static (inside, outside) 1.1.1.1 tcp smtp 192.168.0.1 netmask 255.255.255.255 smtp

  It worked well for incoming and outgoing email except to go to particular mail servers. What was going on, it was that they were receiving messages from rebound as below:

  Where IP address 1.1.1.2 combined with overall command of the client.

  Once I changed the nat to use a normal NAT rather than on a port a whole worked well. Download

  static (inside, outside) 1.1.1.1 192.168.0.1 netmask 255.255.255.255

  My question is can I do nat based on the port works for IP addressing in the two directions or am I stuck with the help of a single IP NAT?

  I guess what is happening, is that the NAT based on the port looks only to conversations from the incoming direction (ie the conversation is with port 25 on 192.168.0.1), no conversations from the outgoing direction (ie the conversation is with port 25 on an external IP address).

  Rgds,

  Peter

  Excellent analysis and you are immediately. Just a simple set-config that lack of most people. Try the following:

  static (inside, outside) 1.1.1.1 tcp smtp 192.168.0.1 netmask 255.255.255.255 smtp

  Global 2 1.1.1.1 (outside)

  NAT (inside) 2 192.168.0.1 255.255.255.255

  The static method will match the traffic from port 25 to the mail server. So when your mail server sends outgoing traffic on one port other that the 25, he uses the nat/global configuration you have defined for the other hosts on the inside interface. Who obviously doesn't like the other e-mail server.

  Hope that's clear, but if not, let me know.

• Change NAT settings

  I'm trying to get internet on my xbox by bridging my network connection Wireless through my pc. The Xbox is connected to the internet and the network bridge is connected but the xbox is telling me that my NAT settings are moderate, which makes streaming movies or play games online almost impossible because the connections is to slow down.

  Hello

  The bridge does not NAT settings, it fills what he gets.

  Wireless connection of the computer may be too slow for streaming movies and his ping to wide for the games adapted.

• 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 and IP directed broadcast

  It is possible to allow (configure) transfer of intellectual property realized emissions from a hosts specified as a source on a running 6.3 PIX firewall?

  I've seen this done on IOS, but could not find a reference for him for the PIX.

  Thank you.

  This is probably more information that you have always dreamed about the topic. Sorry, but I got on a roll...

  By default, for inbound traffic, the PIX will deny the translations for destiny IP that is identified as a network address or broadcast address. The PIX will use the global IP and mask configured 'static' regularly different IP network/broadcast IP. If the global IP is a valid network with a corresponding address mask network then the PIX prevents the xlate to network/broadcast IPs with incoming packet. For example,.

  public static 100.1.1.128 (Interior, exterior) 10.1.1.128 netmask 255.255.255.128

  Global address 100.1.1.128 is considered to be 100.1.1.255 as a broadcast address and network address. Without existing xlate, PIX will deny incoming packet destined to 100.1.1.128 or 100.1.1.255 and following syslog is saved.

  305006: Dst IP is IP nework/dissemination, translation creation failed for icmp src 3rd: 100.2.1.99 internal dst: 100.2.1.128 (type 8, code 0)

  To work around this in cases where the IP is really an IP host, a static separate with host mask must be set up and in front of the static subnet (first game rule for static). The following static method will force the PIX to consider 100.1.1.128 as a host address.

  public static 100.1.1.128 (Interior, exterior) 10.1.1.128 netmask 255.255.255.255

  public static 100.1.1.128 (Interior, exterior) 10.1.1.128 netmask 255.255.255.128

  Note, the xlate can be created by the traffic starts from within host with the IP address in question.

  Slightly a bit clear?

• 506th PIX, no NAT configuration?

  I'm trying to set up a PIX firewall for devices on a valid IP subnet. It is a 506e, with only two interfaces.

  I can't find an example of config and I was wondering if it's because this isn't a supported configuration.

  Pointers?

  Thank you

  Daryl

  Hello

  What you want to achieve, it is possible and very easy to configure. There is no restriction in terms of having no public address on your inside interface. Although you don't want to do any translation that you still may need a static command.

  The minimum config you need would not be nat 0, as some may think, and it works, but only if the PIX cannot be proxy-ARP for the IPS behind the PIX. If the PIX needs proxy-ARP for these addresses, you must configure this way:

  public static 111.111.111.208 (inside, outside)

  111.111.111.208 mask 255.255.255.240

  If you use this command and remove the

  NAT (inside) 0 command it works fine also. The main difference is that, with the static command in place, the PIX not proxy-ARP for the IPS behind your PIX and how nat 0 commands it doesn´t.

  In case you don't need a proxy-ARP you could do with nat 0, but then you have nat 0 on both interfaces to your PIX, so you must:

  NAT (inside) 0 & nat (outside) 0

  Determine if you need proxy-ARP on your border router:

  Is there a route (with the correct next hop) to your edgerouter pointing to 111.111.111.208/28 or your router think it a connected?

  If your router it's a directly connected subnet for some reason (this reason could be that this router is not a classless ip router) then the router wants to send packets to the MAC address and he asks an ARP. In this case the PIX must proxy-ARP.

  Make proxy-ARp is no problem at all for the PIX, cause if you use my first way of configuration, as described previously, then the PIX not proxy-ARP for all addresses in the static command.

  Don t know if this solves your problem, but this could very well be the case.

  Alternatively, you can edit your config here (don't forget to remove the passwords first then) and we can take a look inside.

  Another thing has in my opinion earlier. It could also be the case that your edgerouter has an ARP table that still contains the mappings for the IP addresses which is now behind your firewall. In this case, you need a clear ARP on your border router.

  I hope this helps.

  Kind regards

  I looked on the internet and that it points to a routing error when packets are being encrypted and decrypted, but you can't do a ping on the binding. However when I test the connection I did not enter any of the static routes that networks are connected directly on each side of the pix and the router. any help would be a preciated as I think there's maybe something is blocking the ping to reach the internal network at the end of pix with a configured access list.

  is ping failure of the only thing between the site to site VPN? and assuming that all other traffic works fine since it decrypts and encrypts the packets.

  If it's just ping, then activate pls what follows on the PIX:

  If it is version 6.3 and below: fixup protocol icmp

  If it is version 7.0 and higher: select "inspect icmp" under your political map of the world.

  Config complete hand and on the other could help determine if it's a configuration problem or another problem.

• VPN IPSec with no. - Nat and Nat - No.

  On a 6.3 (5) PIX 515 that I currently have an IPSec VPN configured with no. - nat, using all public IPs internally and on the remote control. Can I add two hosts to the field of encryption that have private IP addresses and NAT to the same public IP in the address card Crypto? What commands would be involved in this?

  Current config:

  -------

  ipsectraffic_boston list of allowed access host ip host PublicIP11 PublicIP1

  ipsectraffic_boston list of allowed access host ip host PublicIP22 PublicIP2

  outside2_outbound_nat0_acl list of allowed access host ip host PublicIP PublicIP

  card crypto mymap 305 correspondence address ipsectraffic_boston
  mymap 305 peer IPAdd crypto card game.
  mymap 305 transform-set ESP-3DES-SHA crypto card game
  life card crypto mymap 305 set security-association seconds 86400 4608000 kilobytes

  ---------

  I would add two IP private to the 'ipsectraffic_boston access-list' and have NAT to a public IP address, as the remote site asks that I don't use the private IP. This would save the effort to add a public IP address to my internal host.

  Thank you

  Dan

  Hello

  If for example you have an internal host 192.168.1.1 and you want NAT public IP 200.1.1.1 it address

  You can make a static NAT:

  (in, out) static 200.1.1.1 192.168.1.1

  And include the 200.1.1.1 in crypto ACL.

• Yahoo email won't load and store settings in the OS x mail application

  I tried to mail yahoo mail OSX El Capitan. Using the Yahoo tab in the box menu for the establishment of new accounts I can get the drop-down list to enter my email address that is recognized by Yahoo saying welcome + the address just entered. I press next to enter my password it is accepted. seconds after the drop falls again ask for the e-mail address and the password again. This time, I get the loading wheel which runs forever. After going to the doctor of connection I find mail forgot all my e-mail address and yahoo settings. It doesn't let me manually as some of the input fields are eliminated. My web yahoo mail warns me that my iMac has connected twice to my yahoo account. I went back into the box selection of accounts once again, before other suppliers named and pressed (other) then I found a button with a blue representative logo email that I have lived the same as before proceeder. Guess what? It loaded perfectly! The only problem is that this article only gives me the apps. Mail and Notes.Nothing else is available. If the Yahoo logo button had loaded, I would also have other Contacts apps.like & calendars + two other institutions. How can I get the missing apps to work using the mail icon settings?

  Is this your first attempt using Yahoo! mail on Mac? I had some weird problems with my own Yahoo! account today, and I know that sometimes he just goes a bit wonky and correct itself on its own. Unfortunately, it's a big part of the reason I do not use my Yahoo! account more.

  Have you tried to manually configure the account as an IMAP account? Y at - it none of the settings of your Yahoo! account to restrict connections and others? You have two-step verification enabled for your account?

• Equium L20-198: error 0271 check date and time settings.

  My apologies if this appears twice, I tried to change and I somehow lost my thread.

  Hi people.

  For awhile, I had problems with my laptop. Toshiba Equium L20-198.

  If I unplug the network at any time, when I re - connect and start the computer, I get two warnings.

  Date and time settings error 0271 check.

  WARNING 0251 system cmos checksum bad default configuration used

  About 6 months ago we replaced the CMOS battery, while we struggled to find a brand new ML1220EI2 Nickel hydrogen 3V 14mAh, we had to go for a "used" quality one.

  The problem persists and I now also get this message every time that I reboot rather put into hibernation.

  Yes, the computer is a little more than 5 years and hit a little, but it is absolutely perfect in all other ways - with one exception - the main battery is completely dead. If the network becomes disconnected, I make you stop in about 3 minutes. :(

  Is it possible that the CMOS battery charge the main battery and this is my problem? I did a little research on Google and found a similar question and an answer on a Dell forum where someone has stated that the CMOS takes his food on the main battery. Would this be the case with my Equium and could buy a new battery solve my problem? I obvioiusly don't want to spend £30 + for it will not help, any response would be appreciated.

  Thank you.

  > Is it possible that the CMOS battery charge the main battery and this is my problem?
  Well, the CMOS battery can be charged with AC adapter but the laptop must be turned on for about 18 to 20 hours.
  It s not I known if battery CMOS takes the power of the main battery
  Usually the CMOS battery should always charge in work and when the laptop is plugged in
  So, theoretically the main battery has no influence on the CMOS battery.

  I think it might be a mobo problem, I think this could be a reason for it

  By the way; in most cases the CMOS battery is not removable... so I wonder how did you repalce this CMOS battery...
