EX90 behind a DSL router

Hello

I want to use EX90 to make a video call over an internet connection. The EX90 is installed behind a DSL router. The DSL router uses a public IP address while the EX90 lies in the private address space. The DSL router performs NAT

But when I try to make a video call, the call is connected but I do not see any video and diagnostics, I see that a single audio track out of my camera.

do we need any specific configuration on the EX90 to work in this scenario?

I have to configure public DSL router address as address H323 NAT for that to work?

Thank you

Ambi

If you had another top config before I'd start with a factory default reset.

I would like to disable SIP:

XConfiguration NetworkServices SIP Mode: Off

And configure NAT:

xConfiguration H323 NAT Mode: auto

xConfiguration H323 NAT address: "88.66.55.33."

xConfiguration H323 profile 1 PortAllocation: static

As you say, 88.66.55.33 ports transmits to 192.168.1.10

These are the required ports:

For direct H.323 calls, the ports used are:

  • Q.931 call Setup: Port 1720 (TCP)
  • H.245 (static): port 5555-6555 range (TCP)

or if you want to use dynamic: H.245 (Dynamic): range of ports (TCP) 11000-20999

  • Media (Audio/video/data/FECC) *: port 2326-2485 range (UDP)

* Configurable by "Range of Ports RTP Start" and "Stop RTP Ports range".

Please remember useful frequency responses and identify useful or correct answers.

  • How to fill Airport extreme wth my DSL router

    I am interested to buy an airport extreme and I currently have a DSL WiFi router. can I fill my current setup and then copy it into the new airport extreme, and then turn off my WiFi in my DSL router? in other words, I wish the Airport extreme to be the main WiFi, I hope I'm supposed?

    You cannot copy between dissimilar model routers.

    And there is absolutely no reason and without having to turn off the current router wifi and every reason to leave it on.

    The extreme must be in bridge including the Apple Installer mode to remove the wireless of comments. So I encourage you to just run two wireless networks... (there bandwidth to run 3 without causing problems).

    Create the wireless on the extreme with your own new values wireless... and you connect some Apple devices you want.

    But you can do what you want... just use the existing router SSID in the airport and use his password... However, this can cause problems for clients who expect a single Assembly and find that they are connected to something unknown.

  • the wpad.home to the dsl router server requires a user name and password

    I recently downloaded some files for Silverlight and Microsoft Microsoft Security Update.  Now I started to get this message when I start my computer that says "the wpad.home of the dsl router server requires a user name and password", there also a warning that this information is requested on a non-secure server.    I hit Cancel and the window disappears and everything works, but I'm afraid that I picked up a virus and I don't want to put the password of my router in this screen.  Is this really a thing of Microsoft, or do I have some type of virus?  I run all my virus software and it found nothing, but I'm still worried.  Is any way to get rid of him?

  • VPN bewtween 2 PIX - 1 behind a NAT router.

    Hello

    I created 2 PIX with a VPN tunnel between them and it worked. Small was during a test well before that of PIX has been shipped to the location where it has been implemented (with of course the new addresses IP etc.)

    Now this PIX is placed behind a Zyxel router running NAT, and the tunnel will not simply come to the top. It is never further than the State of 'mm_sa_setup '.

    I am aware that the only thing that is different from when he worked is the NAT router damn, so I should be aware of this router? I'm going nuts: 0)

    Oh and btw. I use ESP-3des-sha.

    Thanks in advance,

    Rasmus

    When you activate the NAT - T, Cisco PIX automatically opens port 4500 on all active IPSec interfaces so you should be sure that the UDP 4500 port is not blocked between two PIX.

    =================================

    Suppose you have the following in your tnsnames.ora:

    Larry =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = myhost) (PORT = 1521))
    )
    (CONNECT_DATA =
    (SERVICE_NAME = curley)
    )
    )

    Now, when you issue a connect, say like this:

    $> sqlplus scott/tiger@larry

    TNS will appear in your tnsnames.ora for an entry called "larry". Then, tns sends a request to (PORT = 1521) on (HOST = myhost) to aid (PROTOCOL = TCP), requesting a connection to (SERVICE_NAME = curley).

    Where's (HOST = myhost) on the network? When the request is passed to tns to the next layer in the network stack, the name "myhost" resolves to an IP address, either via a file 'hosts' local, through DNS, or possibly other mechanisms being used less. Alternatively, you can hard-code the IP (HOST = 123.456.789.101) in the tnsnames.ora.

    Then, the request arrives at port 1521 myhost. If all goes well, there is a listener on myhost configured to listen on port 1521, and this listener knows SERVICE_NAME = curley. If so, you'll be connected.

    A few important points.

    First, the listener is a process only the side server. It's all in life seeks applications for reception for connections to the databases and set up these connections. Once the connection is established, the listener is out of the picture. It creates the connection. It does not support the connection. A listener, linking an oracle of the House, listening on a single port, use multiple instances of database in several versions of several houses. It is unnecessary complexity to try to have several headphones. It's like the telephone company, to build a separate table for each customer.

    Secondly, the tnsnames.ora file is a client-side problem. Its purpose is to address resolution - the equivalent of the 'hosts' file tns further to the bottom of the network stack. The only reason it exists on a host computer is because this machine also can run client processes.

    What can go wrong?

    First, there may not be an entry for 'larry' in your tnsnames file. In this case, you get "ORA-12154: TNS: could not resolve the connect identifier specified" no need to go looking for a problem on the host, with the listener, etc.. If you cannot place a phone call because you do not know the number (cannot find your phonebook (tnsnames.ora) or can not find the party looking for listed in it (no entry for larry)) you don't look at problems at the switchboard.

    Perhaps the entry for larry was found, but myhost could not be resolved to an IP address (for example there is no entry for myhost in the local hosts file). This will mean by "ORA-12545: Connect failed because target host or object does not exist.

    Maybe there is an entry for MyServer in the local hosts file, but it specified a bad IP address. This will mean by "ORA-12545: Connect failed because target host or object does not exist.

    Maybe the INVESTIGATION period was good, but there is no listener running: "ORA-12541: TNS:no listener.

    Maybe the INVESTIGATION period was good, there is a listener to myhost, but he is listening on a different port. "ORA-12560: TNS:protocol adapter error.

    Maybe the INVESTIGATION period was good, there is a listener to myhost, listening on the specified port, it's unknown SERVICE_NAME = curley. "ORA-12514: TNS:listener is not currently of service requested in connect descriptor.

  • Extend the DSL router?

    I just got internet frontier DSL, and it comes with a wireless router & modem Netgear 7550. I would use my Airport Extreme to extend the reach of wifi at the front of my house and also plug my Airport Express to print wireless, and play music. How can I do this? I don't know anything about networks. Thank you!

    Ask Frontier to replace your modem/router with just a modem, so you can use your own router. Or, if the device has an Ethernet port for the computer, and then connect an Ethernet cable between the port of the modem/router and the port of world on the AEBS. Jam the device border so that the wireless radio is turned off. You should be able to extend the AEBS wireless using your AEX to print and play music.

    Network Apple devices do not extend the networks of non-Apple routers unless you run Ethernet cables for Apple devices installed remotely.

  • OfficeJet 6835: Connection printer/fax to the single telephone line with answering machine and DSL router

    I change my current 2 lines phone/fax with answering machine setup and router DSL to a single line.  I have the right instructions HP and all the necessary parts and wiring diagrams, but I can't determine which of the now used phone cords is 'special' one provided in the box with your printer.  Instructions for the installation of a line saying I should use this cord between the DSL filter and the 1-line port on the printer for reliable fax.

    How can I identify this original HP cord?  And, in case I can't, what makes it "special"?

    Hi @Atlantico,

    Thanks for joining the Forums of HP Support with your request.

    I understand that you change the way that your fax is installed on your HP Officejet Pro 6835 e-all-in-one printer and you want to be able to identify the phone cord supplied with the printer. I would like to help.

    Usually the phone cord supplied with the printer is black and a 2-wire telephone cord. There are basically 2 types of telephone cords, 2-wire or 4-wire. cords 2 telephone wires are the most basic phone cords and because the fax was built around the analog telephone systems, this is the type of cord they suggest to use.

    You can identify a phone cord of 2 sons looking at the end of the connector that you plug into the phone jack. Please see the attached diagram below.

    Please let me know if that solves the problem, or if you need assistance.

  • L2l VPN between ASA with the IP address public and CISCO2911 behind the ISP router with port forwarding

    Hi all

    My apologies if this is a trivial question, but I spent considerable time trying to search and had no luck.

    I encountered a problem trying to set up a temporary L2L VPN from a Subscriber with CISCO2911 sitting behind the router of the ISP of an ASA. ISP has informed that I can't ignore their device and complete the circuit Internet on the Cisco for a reason, so I'm stuck with it. The Setup is:

    company 10.1.17.1 - y.y.y.y - router Internet - z.z.z.z - ISP - LAN - 10.x.x.2 - XXX1 - ASA - 10.1.17.2 - CISCO2911 - 10.1.15.1 LAN

    where 10.x.x.x is a corporate LAN Beach private network, y.y.y.y is a public ip address assigned to the external interface of the ASA and the z.z.z.z is the public IP address of the ISP router.

    I have forwarded ports 500, 4500 and ESP on the ISP router for 10.1.17.2. The 2911 config attached below, what I can't understand is what peer IP address to configure on the SAA, because if I use z.z.z.z it will be a cause of incompatibility of identity 2911 identifies himself as 10.1.17.2...

  • What is the best way to connect a time capsule from the airport to an existing dsl router?

    I have a Netgear D6300 router with built-in ADSL modem and I'm getting a time capsule from the airport. I thought to put the D6300 in Bridge mode and connect the TC via a ethernet cable but my netgear router is kept in a metal TV armoire or I asked myself if I put on the floor and used to extend my existing wireless which is a little spotty on the floor, but I didn't know if the connection on the hard drive would be too slow. However I read in another post is no longer that apple supports the extension of networks of "no apple"?

    The time Capsule will connect to the Netgear router using a wired Ethernet cable connection, permanent... no matter how you decide to configure things.

    Regarding the location, Time Capsule can be located just about anywhere that it will allow an Ethernet connection. If you want to time Capsule to "extend" the wireless Netgear, and then configure the time Capsule to create a new wireless network that uses the exact same wireless network name and password than the Netgear router. The result will be a network of 'big '.

    Should be a lot more work, but assuming that the Netgear gateway can be configured to work as only a simple modem, the Capsule can be configured as the primary network router.
