Bug of Linksys WRT54GC Mode of operation of "router"?

I use a Linksys WRT54GC router and I experience a behavior that I don't expect.
You give me your opinion?
This is the case:

My assumption of "Gateway" or "Router" operating Mode is:
Gateway mode means NAT that makes invisible LAN subnet side WAN addresses. NAT is disabled by activating the Mode of operation of 'Gateway' to 'router '.

I have connected a PC (192.168.2.100) to port the router WAN and another (192.168.23.100) PC on a LAN (192.168.23.1) of the router (192.168.2.2) port.
When I switch my WRT54GC "Router" mode I can't always ping the PC on the site of the side router LAN WAN. SPI Firewall protection and block anonymous Internet requests are disabled. Firewalls on both computers is disabled.

I saw a similar problem at the forum "Connecting two routers via WAN" 08/28/2008 Victor Tang.

Don't you think that it is a bug in the mode of operation of the WRT54GC software?

I reported the bug to Linksys.

My first experience with Linksys technical support is very good.

They take the serious problem, ask for the discharge of Wireshark and send me an update of the firmware of the router.

This fixes the bug with the mode of operation, now I can without NAT on and outside, very well!

I don't have firmware update earlier because the release notes did not mention my bug, I read in the forum a lot of users having problems after the update of the firmware, so I followed the policy do not update unless it can solve your problem.

There are some things perhaps worth mentioning:

You should be careful to use the right firmware for your router.

Not only the model of the router is too important, the hardware version and too country!

I've got a WRT54GC, hardware version 1, and it is the type of the EU.

Of this material, there's also a different US with versions of firmware version!

The latest version of the firmware to the US type is v1.60.1, the latest version of the EU type is 1.60.0 v.

Thus, you should take care of this website, you download the update to get the right version and read the release notes. These release notes, you can check if your current firmware version is part of the history of this firmware, so you know that you have the right one. I was so very accurate because many have reported problems in the forum with updates.

Now I'm able to Exchange traffic between computers and printers in different subnets and I can access the Internet from each subnet gateway I want.

It is important to think about the configuration of your PC and routing tables.

The firewall on the computers must be configured on the additional subnet.

A PC has a default gateway to reach a device on another subnet.

Most of the time these are devices on the Internet, so if you create additional internal subnets that your traffic will be by default will be send to the Internet and will be lost. To define additional gateways where your additional subnet can be found to avoid this.

This can be done on a PC with the command: route add (IE 192.168.23.0 mask 255.255.255.0 192.168.2.2) or you define a static route to your router (the latter is preferable).

The problems I've had, forced me to consider how does networking, with the help of the users on this forum, I would conclude that this is a bug, with the support of very good Linksys everything now works as expected.

Thank you.

  • Cannot connect my HP Photosmart c309g-m printer to my Linksys WRT54GC router. "No filtering = FAIL.

    I have problems connecting my HP Photosmart c309g-m to my Linksys WRT54GC router.  The diagnostics report says "no filtering = FAIL" in all my attempts.

    First I had implemented security wireless to the router with a personal WPA2 password.

    Because this does not work, I spent my WPA security, given that the diagnostic report suggests that this is what he actually uses for encryption. This no longer works.

    I double and triple checked the MAC address of the printer in my MAC filtering wireless settings. He was right. However, he didn't always connect.

    Reluctantly, I turned MAC filtering. However, the printer still wouldn't connect.

    Now, I'm out of options. All possible ideas for this problem?

    Here are a few ideas:

    1. check that the SSID is being broadcast.

    2. make sure that DHCP is active.

    3. don't use MAC filtering (it is not a security measure, in any case).

    4 change the channel from router to 11.

  • HP 50 g: Bug in LASTARG after MOD and other orders of CASES

    I mind not to check if this has been reported before, because it is a bug, and duplicate bug reports should be published until HP fixed them in a new ROM for HP 50g.

    I use the command MOD (in RPN mode in any case), example: 10 ENTER 7 MOD gives the correct answer 3.

    LASTARG appeal immediately after gives an error real mode (!). If it is in the complex mode, or if it end being "politely" beeps to, LASTARG (or ARG on the keyboard) returns 0 instead of 10 and 7 single argument. It's totally false; requiring complex mode (instead of real - the initial calculation has nothing to do with complex numbers!) is ridiculous, and give the wrong answer is just a slap on the face.

    HP 50 g HP50-C revision 2.15 version.

    Hello

    I also have HP 50 g HP50-C revision 2.15 version.

    LASTARG (white-shift YEARS (on the = key)) works correctly for me.

  • Could not load the Mode of operating unit using fndload.

    Hello experts,

    I'm migrating a competing using a TDL of an instance file to another program. As you know has R12 of this security feature where you can run the program with the operating unit single or multiple mode. I ran fndload for download the concurrent program to another instance and it ends without error, but it does not affect the operation of the single unit. It has the value null. If someone has encountered this?

    Here are the steps I did:
    I copied the XXF5_PO_PRINT.ldt file to $FND_TOP, patch, 115, import directory
    Run the following command:
    FNDLOAD apps / DOWNLOAD < < password > > O $FND_TOP/patch/115/import/afcpprog.lct XXF5_PO_PRINT.ldt PROGRAM APPLICATION_SHORT_NAME = XBOL CONCURRENT_PROGRAM_NAME = XXF5_PO_PRINT

    I ran fndload for download the concurrent program to another instance and it ends without error, but it does not affect the operation of the single unit. It has the value null. If someone has encountered this?

    This is set on the source instance? You can find it in the ldt file? If so, you can modify the ldt and try the same command again.

    In addition, please use CUSTOM_MODE = FORCE or UPLOAD_MODE = options to REPLACE and see if it helps.

  • possible bug in colorTransform-related mode full screen (projector and standalone flash player 10)

    Hi all

    It seems to have hit a bug in the current drive (tested on 10.1.52.14):

    If I programmatically change the color of a sprite consisting in a text and a circle the output is different if the application is in mode full-screen (the text is not colored in fs)

    In my class mousedown event handler I call the following (slightly simplified the code to make things easier to understand here):

    var cTrans:ColorTransform = new ColorTransform();

    _hColor =0xD78500
    Recolor the clicked sprite
    cTrans.color = _hColor;

    this.transform.colorTransform = cTrans;

    This is what I get in windowed mode (expected behavior):Capture_w.PNG

    It's the same sprite full screen:Capture_fs.PNG

    I can switch between windowed mode and full screen and the text gets colorful or not, as stated above.

    Anyone got clues about what's going on? I mean that's not supposed to probably not be that way...

    No solution (easy) workaround?

    Thank you very much

    Mike

    Well I tried to make a projector and do not see with it, but then again my install puts 10.0.22.87 in the projector.

    I could try changing the Sprite to a MovieClip and see if that helps.

  • What is the Mode of operation WRT54GS?


    Fix.

    Router mode = disabled NAT
    Gateway = NAT active mode

    This should be the main difference. Sure, it has some effects on dynamic routing (RIP) because with active NAT routes from the local network will not be published and sent to WAN.

    As long as you have your installation gateway mode should work fine, regardless of the BEF. But it is impossible to say without knowing the exact configuration you are trying.

  • Linksys makes a Combo of Modem/Router Wireless N cable

    Does Linksys router wireless n gateway, a combination router and cable modem?

    Currently I have the unit combined for wireless g, but upgrade to wireless-n.

    Thank you!

    I think at the moment that doesn't sell Linksys 802.11n gateways.

    I generally recommend not getting the combined devices, but better to get two separate devices, a simple modem and a wireless router.

    1. you have a far greater choice of products for the router, and they are usually less expensive.

    2. in the event of the death of the router you can still have internet via the modem directly. If the combined unit dies, you are in offline mode.

    3. less functions in a more simple design makes the device and averages more stable and more reliable devices.

    4. you can replace a device at any point. For example, if you pass the ADSL or FTTH cable you can simple replace the modem. You may need to change the configuration on the router but other internet connection so that you can keep the router. Similarly, if two years from now, you want to get the router new generation wireless you can continue to use your modem (if it is still suitable for your internet speed)

    Thanks in advance.

    Enrique,

    On the RV082:

    1. -> Double-WAN management system
    2. Change of balancing load (Auto Mode) at the bottom of the page you will now see binding protocol
    3. Select HTTPS [TCP/443 ~ 443] in the menu drop-down
    4. Select the source IP address or range: (i.e. 192.168.1.100 to 150) that will bind HTTPS for any LAN device that uses an IP address in this range.
    5. Select the address IP of Destination: leave generally to 0.0.0.0 to 0.0.0.0 for all destinations
    6. Select the Interface to bind the Protocol (WAN1 or WAN2)
    7. Check the box enable and add to the list. Save settings at the bottom of page.

    On the RV016:

    1. Management-> multi-WAN system
    2. Look for the setting of the Interface to and select Edit to WAN1.
    3. Follow the steps above.

    Please let us know if this helps or if you need further assistance.

    Yes. It is better to have just a modem ordinary to avoid double NAT issues as well as port easier opening if it is necessary to do so.
