Set AE as an IP passthrough?

Hi
We got my son an Airport Express for his dorm room where they have restrictions on internet connections and don't generally allow WiFi in the rooms. It appears that they use a pseudo-static DHCP scheme - always assigns a 172.xx.xx.xx type IP address to the computer. When using a wired connection, he's able to access the internet. When connected through the AE, no dice. He is able to see the AE and the address it was assigned (same as above). We've gone through the AE setup, but it still won't let him get out. The AE does synch up and gets the 172.xx.xx.xx address.
My guess is that a software scanning process the school requires installed a program on the computer which only allows that address to access the internet. What I am wondering is if there is a way to get the AE to set the WiFi IP address (just one) the same as the DHCP address it gets assigned off the net.
I hope this makes sense. Any chance it could work?
thx

I don't think the issue is the DHCP address that being assigned, as you can set the AirPort Express Base Station (AX) to have a static IP to match (at least temporarily) whats coming from the school's DHCP server.
What I believe the issue is (beside the school's stand on WiFi in dorm rooms) is that they are, most likely, using MAC address filtering. For example, did your son have to provide the MAC address of his computer to "register it?" If so this MAC address would not match the one on the AX.
Unfortunately, in this case, the AirPort base stations don't allow for "spoofing" the MAC address.

    When you set passthrough using the 'passthrough' command in ttisql the new value only remains in effect until you commit and then it gets reset back to the setting in the DSN. This is why you can only use the passthrough command when autocommit is disabled.
    Note that the setting fof passthrough takes effect at command 'prepare' time not execute time annd is saved as part of the prepared command 9same is true when using it in applications). Consider the following sequence in ttIsql:
    autocommit 0;
    passthrough 3;
    prepare 1 update sometabe set somecol = 4 where somepk = 100;
    commit;
    passthrough 1;

  • How to manage coexistance of IIS policy agent and sun-passthrough from AS

    We have an ISS 6 with Policy Agent 2.2 and on same instance we have the sun-passthrough plugin installed to redirect certain pages to an Application mounted on Sun App Server 8,2. We need to apply policies to requests to those pages before redirection is done but seams that passthrough plugin is taking precedence over Policy Agent. Therefore, policies are not evaluated and all traffic is passed. PA agent is installed as a wild card and passthrough as an ISAPI filter. We do not see a way to change priority (already set to HIGH) for the passthrough plugin. PA has the option on amAgent.properties and we set it allready to HIGH. Any hint?

  • DMZ, IP Passthrough and Firewalls

    Hi, I'm trying to play some games online and I have been trying the port forwarding thing but it seems that I have some software firewall blocking my ports and I can't figure which one can be.
    I have Bellsouth DSL, I have set my modem to IP Passthrough to my Linksys BEFW11S4 (V4), and I have set my router to DMZ, so I think there shouldn't be any hardware blocking my ports. After that I disabled my Norton AV & Internet Protection, and Disabled the Windows Internet Firewall. I don't have any other AV or Internet protection installed.
    After all that disabling session, when I try any online tool to check my ports (even port 80) they gave me a "connection timed out" response.
    Is there any way to know what is blocking my ports? Are my ports really blocked? I just want to disable the whole hardware protection and keep the software.
    Thanks in advance

    You already have a NAT firewall on your router....That's ample amount of firewall, but if you prefer to have more protection, make sure your anti virus or firewall software does not limit your network connectivity, there are options in  your software to allow traffic, you should be okay after that...

  • Using USB printer on Sun Ray 2

    Can someone direct me to a document or explain how I can configure the Sun Ray Software to allow me the ability to print to a USB printer attached to a Sun Ray 2 thin client. I believe this is possibele using the USB redirection utility but only when connecting to Windows XP desktops. I see it's being done when connecting to Windows 2003 Terminal Server. Any help or info on this would be great.
    Thanks!

    Here is a repost of my article on the sun-ray users mailing list.
    Lars Tunkrans
    Wed, 27 Jan 2010 09:34:47 -0800
    This article is for using Solaris as the Sun Ray server.
    I have used a Sun-Ray local USB attached printer in two ways.
    Precondition1: The printer was using Postscript rendering.
    The printer had its own rendering engine.
    The printer was NOT a dumb windows-driver dependant printer.
    Precondition2 the user logging on needs to have the printer administrator RBAC role to be allowed
    to create /destroy printqueues.
    1) Printing from Solaris.
    Set up a solaris printqueue with
    lpadmin -p printername -v " sunray devicename" -I postscript -T PS -m printermodel
    This will use the solaris lpfilter mechanism to convert the printdata to postcscript protocoll.
    2) Printing from Windows.
    Set up a solaris printqueue with
    lpadmin -p printername -v " sunray devicename" -m printermodel
    Set up the windows printer with a working windows Postscript driver.
    The windows included hplaserjet-postscript driver works. for a hplaserjet printer.
    or any printer emulating the HPlaserjet like many Xerox printers do,
    This setup will generate the Postscript protocol on the windows PC , and it will merely
    "pass-though" the Solaris spooler without change.
    So if you need to print from both the SR server and the windows PC you need to define two spooler queues for each printer. Below are two scripts that have existed in various versions on sun-rays.org that I enhanced a bit and ran from the VDI superstructure to make it do what I wanted. For windows printing you then need to pass the printername as an argument to the "uttsc" startup command.
    uttsc ......... -r printer $printername .........

  • Quicktime won't recognize entire DivX movie

    I've tried to play a DivX movie that's 2:46:49 long in Quicktime (7.1), but it only recognizes and plays 1:45:46 of it. I open the same movie file in VLC (0.8.5) and it recognizes and plays the entire movie.
    Movie format: 720 x 480, MPEG Layer 3, Stereo, 48.000kHz.
    What gives?
    G4 iMac 1G RAM   Mac OS X (10.4.6)  

    And if Streamclip doesn't fix it,
    Some programs, like ffmpegX, insert a timecode break at the 1GB mark. QT doesn't like it and will only see the first 1023MB of the movie. When you do a 'Show Movie Properties" in QT, I'll bet it shows something like 1023MB for the Data size.
    You can either watch it in VLC or use the fix I use for QT. Because of that bug in ffmpegX, and another one in D-Vision 3, the fix is kinda roundabout.
    First, if the extension is .divx, you need to change it to .avi. Download and install ffmpegX and D-Vision 3 from Versiontracker.
    Open the .avi in ffmpegX, choose the quick preset "Movie audio to mp3". Go to the Audio tab and set the Audio Codec to "Passthrough", hit Encode.
    Open D-Vision, hit the Tools button, select the "re-encoding avi/mpg" option. Then drag the AVI into the "More infos" window. Hit the Copy/Extract button, then Hit the Create task button across from the "Extraction of the video track" line.
    Now you have a copy of the Video and Audio tracks. In D-Vision, Hit the "Show all" button, then Hit the "Add audio track" button. Choose the Video only file and the mp3 file, Hit the Create task button.
    The resulting .avi should work correctly in QT.

  • BT Infinity Broadband - stay away. Extremely poor...

    Just switched to BT Infinity broadband. Unfortunately, I took the limited option as we do not download a lot but wanted the faster speeds. A big mistake. Regret going to BT. Issues that we have faced so far:
    1) Installation could not be done on the first day the engineer turned up. After sending an email and text every day for a week prior to the engineers visit to make sure that we had things ready it turned out that BT did not have their house in order and couldn't install it on the day. They had issued a notice to my previous broadband provider to disconnect, so ended up without internet for a week. BT provided a BT wifi-voucher but that was a world of pain as well with expiring vouchers, dropped connections, etc.
    2) Once the broadband was installed, we stopped getting signal in parts of the house. Never had a problem with my sky router. Called BT only to be told that we should go wired. Wifi has a limited range. I would like to think that my house is massive and wifi doesn't reach all places but unfortunately not. With the previous sky router, we would get wifi 3 houses away. Now - not even within the house. Tried to play around with channels but no luck. Finally ended by buying an extender!
    3) Usage cap: We used up 70% of our monthly limit in 2 days without downloading any movie, any video. Just normal browsing. Called BT and they said that they can't provide details of usage. If it says 70% then it is 70%. If it crosses the 40GB limit, then we have to pay £5/5GB. At this rate, potentially looking at a bill of about £200/month for normal browsing. This can't be right!!
    4) Tried to upgrade to unlimited only to find out that it means taking out a new 18 month contract without any offers. I had signed up to BT Infinity 1 with a 12 month contract at £15/month (£3 off regular price). If I switch to any one of the unlimited packages, then the £3 discount will not be available and it will have to be a fresh 18 month contract. HOW ABSURD! Never had that problem with any other provider. They always had an option to upgrade to a higher package for the remainder of the contract. 
    Over the last month, I have spent over 12 hours on the phone to BT, have spoken to at least 10 different departments and still an unhappy customer. So regret going to BT. Counting the days when the contract will end and I can move away. Only 352 days more to go.

    Hi there
    Welcome to the forum.
    Sorry to hear you have had issues.
    Just a few comments for you. 
    Point 2 - With the WiFi - is the new BT Hub in the same location as your old Sky router? If not, then even minor changes to the location can cause different behaviour due to signal variations.
    Also, you could consider using your Sky router as a WiFi access point. I did that with my old Netgear router. Connected it via ethernet, diisabled the DHCP, gave it a new ip address and set it to just allow passthrough. Worked a treat.
    Point 3 - Usage cap: You need to remember that *any* connection like web browsing, emails, streaming etc will generate data traffic which will be recored as usage. 
    Not sure if you signed up for "BT WiFi with Fon" but this will use a portion of your connection to allow people to use your WiFi. 
    I do not know if this is actually recorded against your usage, but I am sure other Forum users will be able to tell us.

  • Restoring Disk0: when it breaks in 12k XOR routers

    Hi all,
    How to restore the Disk0: contents like corrupted boot image,configurations and file system on the disk0: in 12k routers running with XOR Build.
    1)Is there any options available ?
    2)IS there any best practices to deal with this above ?
    3)Is it possible that only primary RP's config/file system got corrupted and the backup RP is fine? Would then help for a switchover??
    4)IS there any way to check the healthy of the config/file system before rolling back things after a power cycle??

    The firmware is up to date on the Cradlepoint CBR400.  It's definitely not in the CBR400, i've already pursued that.  Even though NAT is required on my end for multiple phones, disabling NAT by setting the CBR400 to IP passthrough mode to allow the phone to pickup the DHCP address from Verizon didn't work either.  This works on a SIP softphone (Bria by Counterpath) and a laptop but not directly to a Polycom phone.  Very odd scenario... The traffic coming from the Bria app on the laptop probably looks slightly different (no QoS tagging for one) than the traffic directly from the Polycom phone, which leads me to believe Verizon is doing some specialized handling of SIP traffic when they see it (probably SIP ALG of some sort) which is breaking hosted VoIP.  For premise based VoIP it might work but a hosted VoIP scenario is different.  Since the server is in the cloud, if Verizon is manipulating those packet headers before it reaches the server (re-writing a real IP with a LAN IP for example), the hosted server won't know where the traffic came from to be able to communicate back and establish the call (SIP signal or audio session).  This is very common (SIP ALG) in today's routing devices.  This is a whole separate scenario to double NAT which I believe they are also doing.  This would explain why the SIP softphone Bria won't work with Verizon 4G LTE behind the NAT of the Cradlepoint CBR400.
    Bottom line is that over the past week i've tested over a dozen scenarios with the 4G LTE and the Cradlepoint CBR400 and determined Verizon is breaking it.  AT&T iPhone tether actually shows some promise except that the Cradlepoint CBR400 isn't compatible with it via USB.  I'd be very curious to know if a compatible AT&T USB device would suffer from the same issues.  In light of my iPhone tether testing i'd have to say no.

  • Exporting selected clips  to MiniDVD

    I am unable to export "Selected Clips" from iMovie6 to my MiniDVCamera(CanonZR60). I was able to do so in earlier version of iMovie.
    The "Selected Clips" box is dimmed when I select "export to Video" (but not so when Quicktime or iDVD selected).
    I can export an entire movie successfully.
    I do have Final Cut Express installed but it has not been used on the movie project in question.
    Any ideas? Thanks

    What do you mean by "passthrough to the camcorder mode".
    In iMovie preferences there is a setting that puts iMovie to passthrough to camcorder mode.
    Passtrough mode means that when you play the video in iMovie, it also appears, through FireWire to an attached camcorder.
    I do all my edits in this mode because a camcorder LCD (and an optional TV attached to the camcorder's analog-out) enables me to see the correct overscan, interlacing and gamma, something a computer monitor can't show correctly.
    To export a desired range in the movie, do as follows:
    - Optionally insert about 10 seconds of black clips to the beginning and end of the desire range (not necessary but this makes the export tidier). (You can prepare the black clips in iMovie by dragging a clip in timeline mode, double-click the created clip to modify its length or color).
    - Put iMovie to passthrough to camcorder mode. Attach a camcorder via FireWire to the Mac and put the camcorder to VTR mode. Now the iMovie video should appear on the camcorder LCD.
    - To export to the camcorder, put iMovie to playback. Then put the camcorder to VTR Rec mode: you have to do this manually via the camcorder's buttons or via its remote.

    Games don't PASS AC3 during gameplay. Only pre-recorded soundtracks like DVDs PASS AC3. Game audio is not pre-recorded, but mixed on-the-fly. The program has a bunch of sound samples to use, and it mixes them together and plays them interacti'vely. Audio would have to be encoded into AC3 AFTER the computer has created the interacti've mix of sound during gameplay. This is not easy to do because it can take a lot of additional processing power. On the other hand, there is no problem with just connecting some PC speakers to the analog outputs on your soundcard.
    If you really wan't use your home theater system for games, you need to connect the analog multi-channel outputs to the analog multi-channel inputs on your receiver (assuming they exist on your receiver). You'll also need to turn on bass redirection in the soundcard's control panel, and IF you have some way to independently amplify the bass channel on your receiver (not the dial on the subwoofer), you'll probably wind up increasing that a bit while playing games because the bass channel will be lower than normal and you need to compensate for this.

  • Connecting the Audigy 2 to a home theater sys

    I've seen a lot of posts on this subject, but have seen a number of different answers. Hopefully I can get a definiti've answer...
    I have an Audigy 2 ZS card (ordered as part of a Dell E50) in my PC and want to connect it to my home theater system. The home theater system has both analog, digital coax, and digital optical inputs. I want to get the best possible sound quality coming out of the PC to play music, thus I would like to have a digital connection between the PC and receiver.
    The question I have is specifically what type of connector do I need to make this digital connection. I have seen people mention using a regular mini-plug to RCA connector, but didn't really say whether that got a digital signal or not.
    I've looked on the Creative web site a bit, and saw some cables, but didn't know for sure which one was the right one. Please advise specifically what kind of cable I should get for this.
    Thanks.

    You will have to ask the store if they have a 3.5mm minijack to RCA cable. Somewhere within the Getting Started program of the Audigy 2 ZS Sound card they have a section which shows you illustrations on how to connect your sound card to different setu
    ps.
    The digital connection will give you the purest stereo signal for your music, but you will not get surround sound unless you are listening to a surround sound?digital feed which the Home Cinema Recei'ver can understand (i.e. Dolby Digital, DTS, or regular PCM). This means that unelss you are listening to DVD Videos?with Dolby Digital or DTS soundtracks, you will only get stereo sound out the speakers, no multi channel EAX, no DVD Audio or CMSS either. Best thing to do is to connect the sound card to the Home theater system using Analog Mutlichannel input. Get 3 3.5mm to 2 Phono Cables. Plug each 3.5mm end into Line out ,2 and 3 on the back of the sound card. At the other end of the cable, match the 2 phono plugs?to the respecti've sockets on the home cinema amp. For example Line out is the front left and right speaker so just match white with Front Left and red with Front Right. Line out 2 - white goes to Rear/Surround Left and Red goes to Rear/Surround Right, irrespecti've of the colour coding on your amp.
    Line out 3 - white goes to Center, red goes to Subwoofer, irrespecti've of the colour?coding again?- am not too sure on this one so be ready to reverse the connections if the speaker test comes out wrong or the "Front Center" voice booms out of your subwoofer!?By connecting it through multi channel analog input, the sound card will do all the decoding, so you can enjoy CMSS, EAX, Neo:6 and any other multi channel pleasure that the Sound Card provides in all its glory. The digital connection will provide purer sound but NOT surround sound unless you invoke a multi channel source such as a Dolby Digital or DTS?DVD, this is of course assuming you have set up the DVD software to correctly channel the sound to the SPDIF out and then set the sound card to passthrough SPDIF signals through digital out!?Good luck and hope that hel

  • Verizon 4G LTE with Pantech UML 290 NAT breaks VoIP with mobile routers.

    LONG story short.  I run a training class once a month (8 road, 4 home) called FreedomVoice University where we train our dealer network on our hosted VoIP phone system called FreedomIQ.  I'm looking to provide my own Internet solution for these classes since most hotels have inadequate (or non-working) wifi and internet.  They typically also lack a wired connection, something that would allow us to connect Polycom (RJ45 connection) VoIP phones for training purposes.  My idea was to use a Verizon 4G USB device that interfaces with a Cradlepoint CBR400 router to provide Internet to a switch that connects multiple VoIP phones.  It turns out that this scenario is impossible to use with hosted VoIP because Verizon has the 4G connection NAT'd.  When you use another router to connect the phones, now a double NAT scenario exists (premise based router providing NAT and 4G connection NAT'd) and that breaks nearly all flavors of hosted VoIP.  Verizon refuses to disable the NAT on their end, citing "security reasons" but I think it's more of a "we don't want you using VoIP instead of our minutes" reason.  Anyway, their 4G LTE service is completely useless to me in this scenario.  Verizon suggested that I turn off NAT on my end.  Apparently they are clueless as to the purpose of NAT.  Multiple devices need unobstructed internet access here guys!!!

    The firmware is up to date on the Cradlepoint CBR400.  It's definitely not in the CBR400, i've already pursued that.  Even though NAT is required on my end for multiple phones, disabling NAT by setting the CBR400 to IP passthrough mode to allow the phone to pickup the DHCP address from Verizon didn't work either.  This works on a SIP softphone (Bria by Counterpath) and a laptop but not directly to a Polycom phone.  Very odd scenario...

    Bottom line is that over the past week i've tested over a dozen scenarios with the 4G LTE and the Cradlepoint CBR400 and determined Verizon is breaking it.  AT&T iPhone tether actually shows some promise except that the Cradlepoint CBR400 isn't compatible with it via USB.  I'd be very curious to know if a compatible AT&T USB device would suffer from the same issues.  In light of my iPhone tether testing i'd have to say no.

  • Sound Blaster Audigy 2 ZS with Logitech Z680 Speakers. HELP

    Okay, I recently purchased the Logitech Z680 5. set w/ the Audigy 2 ZS sound card (not platinum pro version). Im really happy with it, but doing some research on other forums has given me a LOT of questions and confusion. Here is what I need to know:
    To begin with, this section under "support" located at the logitech page (link below)
    http://logitech-en-amr.custhelp.com/...fAaVouh&p_lva=& p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX 3Jvd9jbnQ9MjYmcF9wcm9kX2x2bDE9JnBfcHJvZF9sdmwyPSZw X3BhZ2U9MSZwX3NlYXJjaF90ZXh0PVotNjgw&p_li=
    says that to get TRUE 5. sound with my soundcard and speakers I need to have a digital audio cable that goes from the back of my DVD ROM into the soundcard (like the old ones you put in the back of your CD rom to your mother board to get cd audio). NONE of the local computer stores in the area carry this cable and ALL say I shouldnt need it. WHY do I need it, and where can I find it assuming I do?
    Secondly, it says I need a digital connection to get TRUE 5. sound, not analog. So if I connect a coax from my speakers to the soundcard (using an RCA adapter since it wont fit into the back of the sound card) im getting better 5. for gaming and movies than I will with analog?
    I really just want to take FULL advantage of these two products to give me awesome 5. sound in gaming. This is all I know so far in doing so, PLEASE critique any errors:
    - I had to disable the digital decoder of the Audigy 2 to allow my speakers to decode. I also had to disable decoders built into media software
    - I had to configure both windows and my sound card (and my games/dvd software) to play 5. sound.
    -I had to hookup a digital audio connector from my DVD Rom to my soundcard
    - I had to connect a digital coax from my 680z's to my sound card (along with a mini jack for the coax to fit into the soundcard).
    - I had to select "Digital Output Only" and "Synchronize with control panel" under the speaker settings.
    Assuming ALL this is done, is this everything I can do to take full advantage of the 5. sound this setup can give me, and will digital REALLY give me the 5. sound over the analog, and is there ANYTHING else I need to consider.
    Thank you for your help:-John

    I've just posted a similar question today. I spent hours trawling the web looking at AC3 and everything associated with it yesterday - still not 00% on it though. I'm with you entirely in the game department except my external decoder only has a digital coax input (the optical is for my Xbox) - I don't have the choice of digi vs analogue as you seem to have.
    The only thing I'm not sure if you're aware of is that the set-up you describe doesn't give you Dolby Digital as there is no on-board DD (AC3) encoder. You'll only get DD 5. from AC3 encoded sources like DVDs - you can either set the digital output to passthrough and decode externally or you can decode internally on the Audigy and use the analogues. Not sure which of your decoders is highest quality. I think the 5. you're hearing for games is generated by the Creative hard/software and you'll never get "true" 5. if "true" means Dolby Digital. Having said that, who cares whether it's DD or not if the gunshots sound like they are coming from behind you and you're getting a decent experience ?!
    Maybe you can help me in that respect - f you have set up your system as below (Aud 2 ZS to mini-jack/coax and in to your digi coax input on your external decoder), how did it sound? Did you get all 6 channels during the tests? If you think it sounded good for games then I'm off out to get an Audigy 2 ZS and get going because unless I can find a sound card with AC3 encoder (which I can't), then that's my only option. PLEASE let me know if it sounded good to you.
    Cheers

  • K7N2-L *can* output AC-3...

    I asked this question before Christmas, but no-one could answer conclusively.
    Anyway, I got myself an S-bracket and hooked it up to my decoder with an optical (TOSlink) cable.
    Tried two Dolby Digital trailers in VOB format, and an AC3 test AVI file; the audio set to SPDIF output.
    No problems at all, the Dolby Digital indicator lit up on my decoder and I could hear the files in their full 5.1 glory.
    I'm happy now!  

    Richard, I think you may be confusing "encoding" with "decoding"? I am talking about playback of Dolby Digital in movies only.
    Install S-bracket to the mobo header as shown in the manual.
    I installed the Realtek audio drivers from here.
    The amp that drives my speakers contains a Dolby Digital decoder, and has two digital inputs - coaxial and optical. (Creative® Inspire™ 5.1 Digital 5700). The coaxial input was already connected to my DVD player, so I used the optical connection from the S-bracket with a TOS link optical lead.
    The AC3 test AVI file I used is from here, and the Dolby Digital trailers are here. All these files contain a 5.1 AC3-encoded audio track.
    The AVI file plays in Windows Media Player when AC3Filter is installed; the output is set to S/P DIF passthrough as shown:
    The VOB files were played in VLC media player, but I imagine they would work in PowerDVD or WinDVD, etc. Again, the audio is set to S/P DIF output:
    Edit: Added some more info.
    Edit II: Typo
