Problems getting static NAT to work between two internal lans

Hi, I'm trying the old problem of routing between two internal LANs. This on cli 8.6(1)2. I have three interfaces/LANs; outside is to the internet, inside is the rack in the datacentre and office is a dedicated ethernet link to our office. What I want to do is allow all (for now) traffic betrween office and inside. There's a million hits on this on the 'net but I can't get it to work. Packet trace shows packets accepted from office to inside but blocked from inside to office. Both static nats are set up identically. Here's the output of show nat after packet traces in both directions. It clearly shows that inside to office isn't hitting the nat policy. I enclose what I think are the relevant bits of my config. Full config less passwords + crypto attached.
Manual NAT Policies (Section 1)
1 (office) to (inside) source static inside-office inside-office   destination static inside-ld5 inside-ld5 no-proxy-arp route-lookup
    translate_hits = 0, untranslate_hits = 3
2 (inside) to (office) source static inside-ld5 inside-ld5   destination static inside-office inside-office no-proxy-arp route-lookup
    translate_hits = 0, untranslate_hits = 0
interface GigabitEthernet0/0
nameif inside-ld5
security-level 100
ip address 10.20.15.2 255.255.255.0
interface GigabitEthernet0/6
nameif office
security-level 100
ip address 10.20.11.9 255.255.255.0
object network inside-ld5
subnet 10.20.15.0 255.255.255.0
object network inside-office
subnet 10.20.11.0 255.255.255.0
same-security-traffic permit inter-interface
same-security-traffic permit intra-interface
nat (office,inside) source static inside-office inside-office destination static inside-ld5 inside-ld5 no-proxy-arp route-lookup
nat (inside,office) source static inside-ld5 inside-ld5 destination static inside-office inside-office no-proxy-arp route-lookup

Hi Kevin,
because your interfaces inside and office are in same security level and you have enabled same-security-traffic permit inter-interface, traffic should simply flow between this interfaces. So i think you don't need NAT between this two subnets if there is not other reason to do so.
Then you just configure ACL which will permit traffic you want between this LANs. In this case both netwroks are directly conneted so routing should work(instead of NAT).
Best Regards,
Jan

  • Speed of Working Between Two Internal Hard Drives

    I have two identical internal hard drives, the hard drive in slot-A is the boot drive and contains all my applications, the drive in slot-B contains all my work files (Photoshop and Illustrator files, Word and Excel, digitized video, etc).
    My question is, how much lag time is there with me working in an application on drive-A with the files from drive-B; if any? Is it better to have the work files on the same drive, such as if I moved them all over to drive-A?
    Thanks.

    Going off the advice of the much more experienced guys like Hatter on this forum, the way you have it set up currently is much faster. They even have instructions for moving the user files onto the B drive. I haven't tried that yet, but my iTunes and iPhoto data files are there, and it really seems to help. Many posts on details for doing that in this forum, but I'll defer so as not to take a chance of forgetting some important step.

  • Can Partial Trigger Work between Two Components Which Are in Two Pages?

    Scenario: Some output text components in page one while a SelectOneChoice and a InlineFrame are in page two. At first the resource attribute of inlineFrame was set to point to page one. When changing the value of SelectOneChoice, the values of those output text will be expected to change accordingly. I tried to make SelectOneChoice to be the trigger of those output text components, but found that SelectOneChoice can't be seen when attempt to edit the value of PartialTrigger attribute of those output text components. Then I tried to set the ID of SelectOneChoice as the value of the InlineFrame component, but failed getting the wanted result again.

  • Having a real problem getting my vi to work - great difficulty running sequence as desired

    Hi
    I am have a real problem getting my vi to work as required.
    I would like the my vi (EXAMPLE.vi in the vi library attached) to run continuously.  It should update the graphs on the front pannel and also save data to file when requested using the  save data to file button. (I have written a sub vi. to deal with this data handling and file saving which run in two while loops with the vi as can be seen on inspection of the block diagram)
    Now, what I would like is for the updating to pause whenever I change any of the settings on the front panel (which are controls in the first half of the sequence of the vi) so the hardware is reset.  As it is at the moment I have to stop the vi to change the front panel settings and then restart it in order for the first part of the sequence to run and re-set the values on the hardware.
    I guess I need to use some kind of event driven programming an event stucture or something like that. This is quite advanced and I don't know how to implement it. 
    Can anybody offer any Ideas. 
    Many many thanks

  • Problem with a 1:M relationship between two entity beans

    I am having trouble trying to implement a 1:M relationship between two EJB2.0 entity beans using and EJBQL query. I have an ApplicantEJB, which contains a collection of phone numbers. The applicant table in the database has one primary key, applicant_id. The applicant_phones database table has a compound primary key--applicant_id and phone_type_id--so I have implemented a custom PK class to represent this, PhonePK. I have implemented a findByNameAndPhone method in my ejb-jar.xml file with the following syntax:
    SELECT object(a) FROM applicants a, applicant_phones p where a.applicantID = p.applicantID and a.name = ?1 and p.phoneNumber = ?2
    If I deploy this, Orion/OC4J translates the query in the orion-ejb-jar.xml with an incorrect reference to the applicant_phones.applicant_id column:
    SELECT a.applicant_id FROM applicants a , applicant_phones p WHERE ((a.applicant_id = p.applicantID ) AND (a.name = ?) AND (p.phone_number = ? ))
    I must have something wrong with the ApplicantEJB and PhoneEJB primary key mappings in my orion-ejb-jar.xml file, but I have tried many different combinations of values and keep getting them overwritten by the container with each deployment. Why is Orion/OC4J defaulting the applicant_id reference to the ob[i]Long postings are being truncated to ~1 kB at this time.

    I have posted excerpts from my orion-ejb-jar.xml file in this posting: Problem mapping a 1:M relationship between two entity EJBs w/ a compound PK

  • How to pass data between two internal sessions using ABAP memory?

    Hi,
    How to pass data between two internal sessions using ABAP memory?
    It would be fine if you could explain with an example.
    And also let me clear about the data passing between two main sessions and two external sessions with specific examples.
    Thanks.

    Hi ,
      check the example.
    Reading Data Objects from Memory
    To read data objects from ABAP memory into an ABAP program, use the following statement:
    Syntax
    IMPORT <f1> [TO <g 1>] <f 2> [TO <g 2>] ... FROM MEMORY ID <key>.
    This statement reads the data objects specified in the list from a cluster in memory. If you do not use the TO <g i > option, the data object <f i > in memory is assigned to the data object in the program with the same name. If you do use the option, the data object <f i > is read from memory into the field <g i >. The name <key> identifies the cluster in memory. It may be up to 32 characters long.
    You do not have to read all of the objects stored under a particular name <key>. You can restrict the number of objects by specifying their names. If the memory does not contain any objects under the name <key>, SY-SUBRC is set to 4. If, on the other hand, there is a data cluster in memory with the name <key>, SY-SUBRC is always 0, regardless of whether it contained the data object <f i >. If the cluster does not contain the data object <f i >, the target field remains unchanged.
    In this statement, the system does not check whether the structure of the object in memory is compatible with the structure into which you are reading it. The data is transported bit by bit. If the structures are incompatible, the data in the target field may be incorrect.
    PROGRAM SAPMZTS1.
    DATA TEXT1(10) VALUE 'Exporting'.
    DATA ITAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
    DO 5 TIMES.
      ITAB-BOOKID = 100 + SY-INDEX.
      APPEND ITAB.
    ENDDO.
    EXPORT TEXT1
           TEXT2 FROM 'Literal'
      TO MEMORY ID 'text'.
    EXPORT ITAB
      TO MEMORY ID 'table'.
    SUBMIT SAPMZTS2 AND RETURN.
    SUBMIT SAPMZTS3.
    The first part of this program is the same as the example in the section Saving Data Objects in Memory. In the example, the programs SAPMZTS1 and SAPMZTS2 are called using SUBMIT. You can create and maintain the programs called using the SUBMIT statement by double-clicking their names in the statement. For further information about the SUBMIT statement, refer to Calling Executable Programs (Reports)
    Example for SAPMZTS2:
    PROGRAM SAPMZTS2.
    DATA: TEXT1(10),
          TEXT3 LIKE TEXT1 VALUE 'Initial'.
    IMPORT TEXT3 FROM MEMORY ID 'text'.
    WRITE: / SY-SUBRC, TEXT3.
    IMPORT TEXT2 TO TEXT1 FROM MEMORY ID 'text'.
    WRITE: / SY-SUBRC, TEXT1.
    Example for SAPMZTS3:
    PROGRAM SAPMZTS3.
    DATA JTAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
    IMPORT ITAB TO JTAB FROM MEMORY ID 'table'.
    LOOP AT JTAB.
      WRITE / JTAB-BOOKID.
    ENDLOOP.
    The output is displayed on two successive screens. It looks like this:
    and
    The program SAPMZTS2 attempts to read a data object TEXT3 from the data cluster "text", which does not exist. TEXT3 therefore remains unchanged. The existing data object TEXT2 is placed in TEXT1. In both cases, SY-SUBRC is 0, since the cluster "text" contains data.
    The program SAPMZTS3 reads the internal table ITAB from the cluster "table" into the internal table JTAB. Both tables have the same structure, namely that of the ABAP Dictionary table SBOOK.

  • Cannot get Telnet to work between two servers on same subnet

    I need to test if communication is open on port 8444 between two servers.
    I installed telnet client on a Server 2008 R2 server and telnet server on a Server 2008 SP2 server.  I also manually started the Telnet service that was set to disabled on the SP2 server.  I disabled the Windows firewall on both servers.  They
    are both on the same subnet so they don't need to go through any routers and I can ping successfully.
    When I try to telnet to the remote server by typing telnet "ip address" 8444, I get an error that says "Could not open connection to host, on port 8444:  Connection failed.
    I tried other ports like port 80 and got the same error.
    What else is needed to get this to work?

    VMs have nothing to do with it, as long as there's network communication between the servers.
    As I said, there must be a service or application listening on that port for it to respond. For example, try this:
    C:\> telnet
    When the telnet prompt opens, type in:
    open mail.messaging.microsoft.com 25
    If it works, you should see this:
    220 CH1EHSMHS035.bigfish.com Microsoft ESMTP MAIL Service ready at Thu, 7 Feb 2013 00:57:33 +0000
    That means that Microsoft's mail servers are LISTENING on port 25 and it responded. And note, telnetting to port 25 is a non-default telnet port, because port 23 is the default telnet port. When you type in a space and then a port number, you're telling
    the telnet client to use that port.
    That is the SAME THING if some sort of application or service is listening on port 8444 on that other server you're trying to telnet to. If there is no app or service listening, it will just time out.
    And no, installing the TELNET service on that sercver will NOT answer to any port other than 23. The telnet service by default, uses TCP 23, unless you specify otherwise.
    So once again, what service or app on that server is supposed to be listening on 8444?

  • Static NAT not working

    Hi,
    I'm configuring a 1841 router with 4-port FE WIC card.
    Interface FE0/1 is outside and FE0/0/0 (WIC) is used for LAN connection.
    I'm using dinamic NAT for LAN users access to Internet and static NAT to connect to internal servers from external network.
    In my test configuration, I cannot connect to LAN (192.168.0.0/24) from external network. Dinamic NAT, though, is working fine.
    My config follows. Am I missing something? Hope someone can help me.

  • Problem getting wi-fi to work. please help me.

    Hi,
    In my home, I have AT&T/Bellsouth DSL internet service with a download speed of 1.5 megabits and a Belkin wireless router. I have never had any problems whatsoever in getting any device to work with the network. I currently use two laptop computers, and stream Sirius internet radio over it. Well now with my new iPhone, it doesn't work on my network at all. I can connect my iphone to my network, it shows that I'm connected with a strong signal with all 3 bars on the icon on the screen, though I get zero internet usage with the phone. I went to the Apple Store yesterday and it connected to their network just fine and I had blazing speed, so I know that there doesn't seem to be anything wrong with my iPhone. Would someone please help me? I would greatly appreciate it.
    Thanks,
    Harbeth
    iMac G5 & BlackBook Mac OS X (10.4.10)

    Okay, I now have a solution. I found this information in another thread. I implemented it, and now my iPhone works on my network.
    "After reading many posts with many helpful suggestions:
    I was able to make my iphone work on my home wirless connection by choosing from the main screen
    "settings" then "Wi-fi" then under "Choose a Network" I selected my home network (Belkin) (little blue arrow at the end) then under "IP Address" I chose the "static" button clicked on the "DNS" numbers and entered the the DNS addresses of my router as shown on the summary page when I logged on to my router from my home computer. As for how to log on to your router and find your DNS addresses refer to your router documentation. I tried many of the other solutions and this is so far the only way I could get a connection to actually work. It would always show the strong network signal on my phone but would not be able to connect to the internet and find the server. Like some others who have posted, until this solution I was able to borrow a connection from my neighbor with no problems but his router was a linksys. Hopefully Apple will be patching up all these issues soon.
    I have no idea if this solution is permanent or even a good idea but it worked for me. Your mileage may vary. I do love the phone."
    Thanks to everyone for responding.
    Happy iPhoning,

  • Problem getting PS "template" to work properly after slicing

    Hi guys,
    Just a heads up first, this is going to be a little long for two reasons: 1) I have a bad habit of being verbose  2) I'm going to explain exactly what my problem is and what steps I took to get there so everyone knows exactly what has been done so far.
    So, I decided to give my hand a try at designing a full page template purely in Photoshop (CS4 for PS and Dreamweaver). It worked out great, looks awesome... but I didn't know what to do next. I'm currently enrolled for Web Design & Interactive Media in college, but alas I just started 5.5 weeks ago. However, I do have a photoshop learning center and posted my problem to my professors. After some long discussion of my professor telling me to slice it and just save to web & devices, and me finally being able to get it click that doing this makes a bunch of tables out of the images, I had my first full graphic web template. Problem #1: I have not worked with tables since Dreamweaver was Macromedia Dreamweaver 8... eons ago it seems. So, after finally getting everything into an HTML document, where I felt more at home, I started to play around with the tables, trying to remember anything at all about them. My professor helpfully suggested nesting the tables... it was greek to me. However, we live in the internet age, so I googled it up.
    Now I have my images all in wonderfully organized tables, except for five of the images. This is the jpeg of the template. So, I was loving the template, and that is the photoshop .jpg I saved to show my girlfriend what it would end up looking like. After realizing that I had NO idea how to get the text over those specific area's while the "content boxes" were still in tables, I decided to throw in my puny skill in CSS. I made new slices, and sliced up the upper two sections for the content-title1 & content-title2 and then made 2 more new slices for content-left and content-right, then a fifth slice for the bottom of the rounded boxes content-footer. Now, I have used others' templates in the past such as this site but he was using familiar territory for me.. <div> tags. Ok, so anyway I have 4 new tables to throw in... one each for the content headers "News" and the "Welcome to Illuminati" parts, and then two other boxes for the actual content of each section. After trying to figure out how to nest tables, I gave it a shot and while in design mode, it actually works... except the navbar is slid out far to the right. And when I uploaded the site, not only is the navbar way out in deep right field, but my content-right table slid under content-left. You can see the end result here.
    What I need help on:
    If any kind soul could please take a look at my code and tell me exactly where I'm fubarring things up, I would greatly appreciate it!
    If said kind soul could show me how to fix said problems, I would appreciate it even more!!
    Lastly, on that Livengood Investments website, if you notice the bottom section where the "article of the week" and thumblist is, with that guys' template, as I add content to those sections, it grows down so that you never have gaps or spaces etc. That is why I cut the middle content boxes into two, so that I could add content without worry of having the gaps etc. I did notice though, that if one side is longer in text than the other (on my secondlife.lift4ullc.com/test2.html site) then the other side has a gap. I'm going to assume this is because with the Livengood-Investments site, that middle section is actually 1 background? I could do the same with the boxes on my site, make them 1 section instead of two, if only I knew how to have two separate tables over their individual box... thanks!
    Every guide or tutorial or video I have found on the net about nesting tables gives you a simple 2 column 5 row walk-through. Very nice, and handy in some cases I'm sure, but I can't see how that helps me at this particular moment. =( Thank you in advance everyone, for your patience while I rambled, and your help in this matter.
    Matt

    Wow, quick replies! I knew there was a reason I love the Adobe forums over my normal haunt at Web Designers Group (WDG)! ^.^ Although, in fairness to them, they've been helpful before as well. Now, on to the replies....
    @SnakeEyez02: PM coming your way, thank you so very much! With the www.livengood-investments site, what I did was google up "free web templates" and found that layout (different background, and some customization to it to make it fit the company etc) but it was almost purely CSS done. I would say I've been working with CSS in some form or fashion for roughly 2 years, but only within the last 1-2 months have I really sat down to try to learn CSS. Table layouts (for me) are a thing of the past, when everyone and your uncle had a geocities or some other website. Thank you for letting me know this is possible to do without all of the tables... that is a huge relief and load off of my shoulders. http://secondlife.lift4ullc.com was my "first run" test at the website you've seen, and I've already gone in detail over that code to see why I have the gaps in my logo/header/navbar area, because for some reason I changed the size of those div's that were larger than the images But, I tried out that CSS site before I learned about slicing in PS, so that is why the color scheme is so different. I left it as it is because I would rather have my nifty content boxes ;-) Ok, so I have the starter, and I'll step back and just save the images and not the images + html. From there I'll start designing the site with CSS and div tags instead of the dreaded tables. Like I said though, PM coming. Thank you in advance for the help, I hope I don't make it too difficult for you
    @Boss Yes, I just started college, but I'm 28 now and have been meddling in some form or fashion in web sites for nearly 15 years. I just decided in the past month or so to actually turn it from a "hobby" to something more serious with the hopes of actually making a career out of it. I agree with you that CSS design is better than tables. I hate tables, haven't used tables in many years, and CSS is just so much easier to tweak and read the code than a page full of table coding (as I've learned these last few days). I know I'll be learning some coding in my later courses (today was the end of my first term freshman year) such as PHP, JavaScript, and I *think* some C+/++. CSS, I'm not really sure on. I have no doubt though that I'll be able to bug my professors that teach the courses for CSS... they should be up to date with standards and coding. This professor is actually a Photoshop specialist, and while I'm sure he knows some HTML and CSS, probably not as much as a coder or web developer (as opposed to him being a graphics designer). Thank you very much for the tutorial link, I really do appreciate it. I love tutorials, but sometimes the search for a good tutorial can be almost as fustrating as trying to figure these stupid tables out LOL. However, as I mentioned above, now that I know I can, I am switching over to CSS with yours and SnakeEyez's suggestions. Thank you Boss!

  • How DHCP scope will work between two Wireless contoller

    Dear All,
                 I would like to inform you that we are going to deploy Wireless Network with redundancy of Wireless LAN Controller and we need to figure out how DHCP scope would work during fail over  any one of Wireless LAN controller and DHCP Server .I have two site where Two Differenet DHCP Server would be palced with different DHCP socpe.So My query is that if Site-A(according to attached diagram) DHCP Server and controller fails how Wireless  client will take the DHCP scope from Site-B(according to attached diagram) DHCP Server as it has been configured different DHCP Scope.Can any one tell me whether i can configure same DHCP Scope at Both Site's DHCP Server.
    Is there any way to configure same DHCP Scope for two sites.For your infromation client wants two Different DHCP Server with different scope for Two Site and how redundancy would be ensured if any one WLC or DHCP goes down.
    I am eagerly waiting for your reply as early as possible.Please help to figure out the solution.
    I am going to attached Sample Design for your reference.
    Thanks and regards
    Erfan

    Erfan:
    My query was that if one wireless client already associated
    WLC-A with one IP block of Location-A (DHCP Server) using SSID named TEST. If DHCP-A or WLC-A goes down then how that same client would associate with WLC-B and get the IP Block from Location-B (DHCP Server) using same SSID name TEST.
    In this case the clinets connected to the APs in location A will disconnect (if the WLC went down) and they have to connect again when the APs join WLC-B. They will get IP address from location B block then.
    If DHCP went down when new clinets try to connect the primary DHCP is down so they are referred to the secondary DHCP. connected clinets will disconnect only when their DHCP lease times out. They will try to renew but the DHCP server is not available. They will disconnect then and connect again and getting IP from B site.
    1. How we will create same policy for that two different block using same SSID.
    what policy? where?..etc?
    2. client would be connected with Access point but they will get the IP through VLAN interface of the Controller and we have to assign IP helper address in the interface vlan.So how the the client would get the IP block if we assign two IP helper address in the interface vlan in case of failure of DHCP and WLC of one location.
    3. If we assign two IP helper address then which DHCP Server will release the IP for client and we can make delay between two DHCP Server to release the IP address.
    If two IP helpers are configured the switch will send them both the client's request and they client receives two offers. The clients chooses one of the offers. Usually the clinet will accept the faster DHCP server to respond.
    If you are using the DHCP on the WLC then it is different. The WLC will always try to reach the primary DHCP server as long as it is reachable. If the primary DHCP is not reachable then it falls back to the secondary DHCP server.
    Note that when you use IP helper then you usually disable DHCP Proxy feature on the controller. Do you have it disabled?

  • Problem Getting An Applet To Work

    Hi,
    I hope there is someone out there that can help me with this problem.
    I'm trying to get an applet to work inside of IE6 and I'm getting the following error message via Java Console,
    Error loading class: demo
    java.lang.ClassFormatError
    java.lang.ClassNotFoundException: demo
         at com/ms/vm/loader/URLClassLoader.loadClass
         at com/ms/vm/loader/URLClassLoader.loadClass
         at com/ms/applet/AppletPanel.processSentEvent
         at com/ms/applet/AppletPanel.processSentEvent
         at com/ms/applet/AppletPanel.run
         at java/lang/Thread.run
    The java code is as follows,
    import java.applet.*;
    import java.awt.*;
    public class demo extends Applet {
    public void init() {
    public void paint(Graphics g) {
    g.drawString("Hello World", 50, 50);
    And the html (demo.htm) is
    <html>
    <head>
    </head>
    <body bgcolor="#00DCFF">
    <applet name="demo" code="demo.class" width="300" height="200">
    </applet>
    </body>
    </html>
    Both demo.htm and demo.class are both in the same directory. I used the Sun Java SDK version 1.4.1 to produce the class.
    I can get it to work if I enable
    Java (Sun)
    Use Java 2 v1.4.1 for applet
    within the Advanced options of IE6, but I don't want to have to force the user to have to either load the the SDK or the plug-in (by using OBJECT/EMBED) due to their size.
    thanks in advance,
    Wayne
