Linksys WRT54GL - illegal subnet mask message

Hello everybody,
I just changed the ISP and the new one is on optic fiber, and they arrived with theirs equipment, wich is a Huawey EchoLife HG856 and I connected it to my Linksys WRT54GL.
When I tried to configure the router with the settings gived by the provider i received the following message:
"illegal subnet mask".
The setting given to me by the provider are: (i replaced some numbers with *, for privacy)
Where is the problem?
adresa de IP: 1**.27.1*4.6
netmask: 255.255.255.128
gateway: 1**.27.1*4.1
DNS1: 1**.2*1.2*2.1
DNS2: 2**.1*4.1*4.1

Try to hard-reset the router for 1 minute,power cycle the router and check again.

  • RFC for subnet mask

    Which RFC describes the illegal subnet masks (255.255.255.254, 255.255.255.255)?

    Hi,
    RFC 4632 would probably make useful reading. To quote section 3.1 :
    "In CIDR notation, a prefix is shown as a 4-octet quantity, just like a traditional IPv4 address or network number, followed by the "/" (slash) character, followed by a decimal value between 0 and 32 that describes the number of significant bits."
    So, this basically says your subnet mask can be any value from 0 (i.e. a default route) to 32 (i.e. a "host"). In your example 255.255.255.254 is 31 bits and 255.255.255.255 is 32 bits so both are valid.
    There's a nice table that illustrates this in the RFC as well.

  • How to configure network printer with Linksys WRT54GL router network

    I just bought a Linksys WRT54GL router and I am planning to build the following home-network around it:
    1. A desktop computer connected to router via ethernet cable (hard-wired).
    2. An HP Network Printer (Color LaserJet CM1312 MFP) connected to router via ethernet cable (hard-wired).
    3. A notebook connected to router via Wi-Fi.
    I want both computers (desktop and notebook) to be able to share files, and also to share the same network printer.
    a. How do I do this?
    b. Do I need to install the printer drivers in both computers as if the printer was local for each one?
    c. What settings do I need to include in the Linksys router settings (and also the printer settings) to allow all this? I've read on the internet about DHCP configs, IP address, etc. but I hardly understand anything.
    A step-by-step ("for dummies") explanation will be extremely appreciated.

    You will need to install the printer driver on each computer that will be using the printer.  You will need to have a printer driver that is designed to be used on a network.   Many of HP's drivers (but not all of them) can be used for either a USB or a network connection.
    Usually, when you use HP's printer installation software, it will walk you through the printer installation procedure, and install the printer drivers.  This software is normally located on a CD that came with the printer.  Some installation software demands that you setup a USB connection first, then switch to a network connection.  Other installation software might install a network connection directly.  Just follow the HP directions.
    There are no special settings in the router.  Simply wire (using an ethernet cable) your printer to a LAN port on the router, when the installation software (or instructions) tells you to do so.
    Your printer will likely get a different LAN IP address (192.168.1.x )  from time to time.  Some printer drivers can handle this and still work properly.  Other printer drivers get confused, and cannot find your printer when it changes addresses.  If your driver has this problem, then you will need to assign your printer a fixed LAN IP address.  This will force the printer to have the same LAN IP address each time you boot up your network.   If you need to do this, you will need to enter the LAN IP address directly into your printer (Sometimes this is done using the printer's buttons and display panel, and sometimes this is done using HP printer software).  Note that any fixed LAN IP address must be outside your DHCP server range (defaults are 192.168.1.100  thru  192.168.1.149 ) , and it cannot end in 0, 1, or 255.  If you need to use a fixed LAN IP address, I would suggest you use 192.168.1.13 , which should be easy to remember by looking at the model number of your printer.   If you need to use a fixed LAN IP address, you will also need to enter the Subnet Mask 255.255.255.0, Default Gateway 192.168.1.1 , and DNS Server 192.168.1.1 , into your printer.   If you use a fixed LAN IP address in the printer, you do not need to change any settings in the router.  The router will automatically find your printer when you turn your printer on.   Even if your printer is using a fixed LAN IP address, your computers can continue to get their address automatically from the router's DHCP server. 

  • "IP and router address not consistent with subnet mask"

    Hi all,
    i have one of the old Powermac G5's running os x 10.3.5 "Panther" with a dual 2.5ghz processor, 512mb or ram, 160 gig hd, and no wireless card. I've been trying to hook the computer up to my network via an Ethernet cable (I have a Linksys WRT54G series router).
    the problem is this: When I go through the Network utilities using the "assist me" option, select the LAN option, put in the necessary information (IP address, subnet mask, router address, and the dns host), and select continue, this message pops up:"IP and router address not consistent with subnet mask".
    What I've found is that no matter if the computer is plugged in with a cable to the Ethernet port the message comes up which is very unusual.
    Thanks in advance.

    Have you verified that you indeed have the proper subnet entered?
    Why don't you just let the Mac obtain its ip address from the router via DHCP?

  • Assigning non-standard subnet mask to local IP address on WRT54GX

    I need to configure my WRT54GX V1 as an access point.  I know how to accomplish this, but our corporate network uses a subnet mask of 255.255.252.0  How can I assign this net mask?  The only options are contained in a drop-down menu and what I need is not there.  Is there a different way to assign the subnet mask rather than using the menues?

    It is a known limitation of Linksys wireless routers that they only support LAN subnets up to 255.255.255.0. I guess the assumption was that the router only runs LANs for up to 253 LAN devices. The plain access point setup (i.e. uplink through LAN-LAN connection) was never properly considered an option although it is documented in the Linksys easy answers.
    Anyway, to set up the WRT as access point the LAN IP address of the WRT and the subnet mask is not important for the wireless connectivity into the LAN. The LAN IP address and subnet mask is only relevant to access the web interface of the WRT to make configuration changes. You have to make sure that the DHCP server on the WRT is turned off and that a LAN port of the WRT is wired to your existing LAN.
    For the LAN IP address setup you have three options:
    1. Use an available IP address inside your LAN and use subnet mask 255.255.255.0, e.g. if your LAN uses 10.0.0.0/255.255.252.0, assign the WRT an IP address of 10.0.3.200 with subnet mask 255.255.255.0. Of course, in that case you are only able to access the web interface of the WRT http://10.0.3.200/ from a computer in 10.0.3.* because that's the IP subnet which the WRT thinks is connected to its LAN ports. You cannot use a computer with IP address 10.0.{0,1,2}.* because the WRT does not know how to route these IP addresses. If your computer has an IP address outside the configured WRT LAN subnet you must temporarily change the IP address of the computer.
    2. If you assign a LAN IP address and subnet mask to your WRT which includes a network router you may be able to get full connectivity by setting up static routes in the WRT. For instance, if you assign 10.0.3.200/255.255.255.0 to your WRT and your main LAN router sits at 10.0.3.254/255.255.252.0 you may be able to set up static routes for destinations 10.0.0.0/255.255.254.0 and 10.0.2.0/255.255.255.0 (or if it works even simply destination 10.0.0.0/255.255.252.0) to gateway IP address 10.0.3.254 on the LAN interface. Traffic from the computer to the router should go directly while the responses from the router to the computer go through the main router. I think this should work although I am not 100% sure.
    3. Use any IP address outside your LAN, e.g. the default 192.168.1.1/255.255.255.0. Again, you must temporarily set up a static IP address on your computer to gain access to the web interface. But even with a LAN IP address outside your LAN the WRT will still bridge wireless clients into the LAN as it is supposed to do.

  • How to configure the eth1 port of NIcRIO 9024 to another IP address and subnet mask

    Hi ,
    I am using cRIO 9024 and am planning to configure it to be an MMS server that interacts with a client which is in another network with different IP and subnetmask. I want to run the server VIs from the host computer via the eth0 port and want to communicate the MMS messages through the eth1 port. the eth0 port is configured as a static IP as shown in the screenshot attached and would like to assign a separate IP and subnet mask to the other port . But when I try to save the configuration I get the error "Could not save your changes tot he target.The subnet mask for eth1 is invalid" .
    I have already directly cross connected the Crio and have disabled the firewalls and still am not able to configure it.
    1) is it possible to configure the ethernet ports to have separate IPs corresponding to different networks and thus the subnet masks?
    2) If its possible then what is the mistake i am doing while configuring it ?
    I would be extremaly grateful to have a reply on this as its pretty desperate to spend a lot of time just to set up the IP configurations..!!!!!
    Regards
    Abhinav

    Dear Abhinav,
    I'm sorry but what you are tryining to do is not suported by the Second Ethrnet Port on any cRIO and so you getting this error meeage.
    Here a abstract out ouf the KnowledgeBase How do I Configure the Dual Ethernet Ports on Real-Time Controllers?:
    Ethernet port 2 is currently not supported to communicate outside its own subnet. There is no capability of configuring the Default Gateway for Ethernet port 2 and therefore cannot connect to a large isolated intranet.  However, there appears to be a common misconception that this port can only be used for communication between NI products: this is not the case, though any communication through the secondary port must be within the same subnet.

  • Ip address & subnet mask !

    I have recently encountered a problem with my system and the assigned IP Address and was not sure why. I have a wireless connection on the iMac with it setup to get the IP address automatically but the system gets the wrong subnet mask every time. It gets (255.255.0.0) the correct subnext mask in the other mac's is (255.255.255.0). Where is it getting the inappropriate address and why does it didn't assign the correct one!!

    Are you sure that both these macs are getting IP addresses from the same place? (1 wired, 1 wireless...might mean that mac2 is getting neighbor's wifi)
    Are you certain that this trouble mac is configured to be fully Automatic in the NetworkSystemPreferences?
    "Conigure IPv4...Using DHCP" ( not manually, not dhcp with manual address, not bootP...)
    Have you done a cold start to all your network devices (macs, router, modem, network printers?)
    Power-cycle them off. Count 2 minutes. Start up modem, pause. Start up router/BaseStation, pause. Start up mac(s).
    You haven't said what kind of router/baseStation you've got. 'Twould help, maybe.
    added: Do you have a wireless modem/router AND a wireless airportBS/router/something)?

  • Help with a Subnet mask solution?

    This is probably obvious to many of your network guys/gals - but I'm stumped - I'm looking for an easy solution to this.
    I have a Linksys wireless router WRT54GS - Comcast cable broadband - my MacBook wasn't staying connected to it so I plugged in my Airport Express to one of the Linksys ports via Ethernet and disabled the wireless on the Linksys.
    Bingo - no more connection problem - the Linksys handles the wired users and the Airport Express handles the wireless - except - I have a network drive connected to the Linksys via Ethernet that my wireless users can't "see" - I believe - because it's on a different subnet mask.
    Is there an easy way to "link" the two so my wireless users can see the wired network drive?
    THANKS!

    As both the Linksys and the AE act as normal switches with no routing functionality, you have one single subnet. So all you have to do is to make sure that all devices connected to the Linksys and the AE have an IP-address of that subnet and the same subnet mask.
    Most routers have a class C private network configured by default. Let's assume, you have 192.168.0.0/255.255.255.0. If so, pick an IP-address out of the address range 192.168.0.1 to 192.168.0.254 for each device and use 255.255.255.0 as a subnet mask. For other class C private networks use the according range.
    If you need to mix different class C networks (e.g. 192.168.0.x for your wired deviced and 192.168.1.x for your wireless devices) use a subnet mask of 255.255.0.0 on all devices.
    Just for your understanding: when a machine A connects to a machine B, machine A takes it's own IP-address (e.g. 192.168.1.1) and ANDs it bitwise with it's subnet address (e.g. 255.255.255.0 would result in 192.168.1.0). Next it does the same again, with machines B IP address and it's own subnet mask. If both results are the same, both machines are on the same subnet, so machine A tries to connect machine B directly. If not, the machines are on different subnet, so machine A tries to connect to machine B using it's configured default gateway.
    Hope this information helps at least a bit.

    I don't have the Admin Utility in front of me at the moment. However, as I recall, you need to deselect the Distribute IP Addresses check box...I believe it's on the Network tab.
    This puts the device in Bridge Mode and it will pick up a dynamic IP from your Linksys router.

  • The subnet mask on the Extreme isn't the same as on the Express.

    Dear Group,
    I have my Extreme configured to do PPPoE and DHCP and my DSL modem is setup as bridged. Everything is finally working well. I have an Express extending the Extreme in a WDS.
    When I look at the PPPoE tab in the Internet tab of the Extreme in AirPort Utility it shows a subnet mask of 255.255.255.255, but the Internet tab of the Express shows 255.255.255.0.
    I don't have any problems at all and wireless clients are connected to the Extreme and the Express.
    Is the Extreme's subnet mask part of my DSL connection and therefore a different subnet mask?
    Not sure, but I'd like to make sure that I don't have something setup incorrectly.
    Thanks,
    Frank

    This really isn't an issue as long as the AirPort Extreme base station (AEBS) is providing a working Internet connection. Since the AEBS is using PPPoE to connect to your ISP I'm not sure that the subnet mask is even used.
    The subnet value of 255.255.255.0 used by the AirPort Express (AX) is typical.

  • Subnet mask 255.255.255.255 assigned to VPN client - can't ping LAN

    Hi,
    I configured PIX 501 with PPTP VPN to connect to the small office (PIX FW, Win 2000 Server, several Win clients, LAN IP 10.0.0.X/24):
    ip local pool mypool 10.0.0.101-10.0.0.105
    vpdn group mygroup accept dialin pptp
    vpdn group mygroup ppp authentication mschap
    vpdn group mygroup ppp encryption mppe 128 required

    vpdn group mygroup pptp echo 60
    vpdn group mygroup client authentication local
    vpdn username xxxx password *********
    vpdn enable outside
    I can connect to the office using Win VPN client, but I can't ping any hosts in the office network. I suspect that the reason for that is subnet mask assigned to the VPN client: 255.255.255.255. ipconfig of the VPN client:
    PPP adapter Office:
    Connection-specific DNS Suffix . :
    IP Address. . . . . . . . . . . . : 10.0.0.101
    Subnet Mask . . . . . . . . . . . : 255.255.255.255
    Default Gateway . . . . . . . . . :
    Default GW is missing too, but I think this is not the main problem.
    Any way, what is wrong with my config? How to fix subnet mask assigned to clients? Or may be my assumption is wrong and this mask is ok? What is wrong then?
    Any input will be greatly appreciated!

  • Leopard wifi issue: subnet mask?

    I have the common Leopard wifi problem:
    4 computers, all linked to new Airport Extreme with 10.4
    3 of 4 link with Leopard.
    Have tried all suggestions to fix the problem with the IMac G5 that won't link.
    Always says that the iMac has self-assigned IP and can not connect
    Noted that when the problematic machine does rarely link, Subnet Mask is 255.255.255.0
    Same with all linking machines.
    When doesn't link, subnet mask is 255.255.0.0.
    Does this give any hint as to the problem.

    This might not be related, but you could try changing the DNS settings in your Router to use OpenDNS instead of the number automatically set by your ISP. You just need to manually enter the 2 numbers:
    208.67.222.222
    208.67.220.220
    There are good instructions on the OpenDNS website. It's worth trying just to see if it solves your problem:

    no open apps ...
    I did a bit of testing today and discovered, that the connection doesn't close, only when I exit OVI Store (this happens with WLAN and also with 3G/UMTS connection).
    When I exit any other app (e.g. Browser, Opera, ...) the connection closes automatically after I have closed down the app.
    So this must have something to do with the OVI Store, probably with the new version as I cannot remember to have experienced this until some days ago.
