Are UDP 500, 1701 and 4500 ports being blocked -- VPN ports ??

I recently set up a VPN back into my network (for use on public wi-fi, keep they prying eyes away). 
Everything was working and now it is not.  I checked the access to the port via the internet and they are now closed.
Is VZ blocking UDP 500, 1701 and 4500 now.

#1 Is the computer that you are forwarding to a Static IP? 
Yes, the server on the inside is a static IP.
#2 Is that Static IP outside of the DHCP Range of the router?
Yes, the static iP is  well above my 4 devices that get their normal dhcp address
i put the starting VPN DHCP address well above my static IP  and yet below where the set boxes start using IPs.
#3 If you don't know what the DHCP Range of the router is, it would help to know the brand and model of your router.
I believe the router is the standard VZ issue ActionTek MIR some model, can dig it up when i get home.
Things to note: 
All my other port forwards (ssh, http, https) are still working, they terminate on the same host as the VPN.
DNS is up-to-date as i can still access the box from the internet  (I am using dyndns updater).
I nmapped from the internet to my host on ports 500, 1701 and 4500 and they are close, where my other port forward ports are open.

  • ITunes proxy authorisation window does not appear (and account is being blocked randomly)

    Many users have iTunes installed on their PC. iTunes requires proxy authorization to connect to internet. Appropriate popup window appears when opening iTunes and trying to open some internet-based page there. Entering current AD account credentials helps to connect. There is also a checkmark there allowinf to save credentials for further use (and do not show this window anymore). When AD password is changed - this popup window does not appear again and user's account is being blocked (because iTunes tries to connect proxy with old credentials). The question is: is it possible to reset proxy settings, stored somewhere inside iTunes somehow? Just to return proxy authorization window back. Did you have such an experience? If you caould share any knowledge - it would be great.

    What happens if you go to iTunes > File > Devices, do you get the option to Sync iPhone?
    You could try a reinstall of iTunes. OS X Yosemite: Reinstall apps that came with your Mac

  • VGA and HDMI ports are next to each other; any VGA cable blocks HDMI port; want 3 displays.

    The VGA & HDMI ports are right next to each other on the left side of the laptop.  I ultimately would like to connect two monitors to it, but am unable to occupy both ports because the everyday end of a VGA cable/extender is too wide. Any solutions?

    Hi, Firstly you won't get 3 displays without buying more hardware for your dv7 that why you won't be able to plug 2 ports at the same time. Regards.

    I'm setting up VPN server and need ports 500, 1701, 1723, 4500 open
    Thanks
    -Allen

    Depending on the exact set-up of the network, L2TP requires UDP ports 500, 1701 and 4500 and the IP-ESP protocol, which is IP protocol 50; ESP. 
    Other than ESP (which is protocol 50 and not port 50), these are UDP ports, and not TCP.
    TCP 1723 is used for PPTP.  Not L2TP.
    It is common for L2TP passthrough to fail when more than one connection is active.
    As compared with L2TP, PPTP is usually easier to get going around NAT.  Though conversely, L2TP is rather more secure than PPTP.
    Check your Mac OS X Server firewall settings, too.  If you have some outboard network device providing a NAT gateway, try dropping the server firewall.
    Use of an external firewall-gateway with an embedded VPN server is something I've variously recommended, too.  (I find that VPN NAT passthrough is something best avoided, as VPNs and NAT are operating at crossed purposes.  VPNs seek to keep connection end-points known, while NAT tries to hide those connection end-points.  Doing the VPN processing on the Internet side of the NAT is just... well, easier.)
    Also ensure that your ISP is not blocking VPN connections.  While you might be on static IP, confirm the ports are open.  Trust, but verify.  Get yourself a UDP port scanner, and have a look. 
    If it's permissible within your ISP service tier (and depending on what protocols you're testing), probe the specific target ports using telnet or the openssl s_client command and (particularly for this case) the nc (netcat) tools, and see if the ports allow access.  nc can run port probes on UDP, which is the key piece here given telnet and s_client target TCP and TCP SSL connections.  Probably something like the nc -zu w.x.y.z udp-port command.

  • VPN: Port-forwarding OK but Nothing Talking

    I've set up several 10.3 & 10.4 VPN services but this one has me puzzled...
    10.4.2 Server (does it just need updated?)
    Internal ip only (no firewall on server) with router forwarding UDP 1701, 500 & 4500 (for L2TP).
    When attempting to form the VPN with remote (wan side) Internet Connect client, there is no connection showing in vpnd.log (set to verbose logging) and no connection showing on Internet Connect log. It's like the port forwarding is not taking place. However...
    If I run a port scan from remote machine, on UDP 1701, 500 & 4500, this traffic shows up on a TCPDump session running on the server.
    Attempting to form the VPN, however, shows NO traffic with TCPDump.
    The IP address of the server, in Internet Connect, is correct (same as the one used during port scanning). The VPN client is able to connect to several other servers OK.
    Any ideas?
    Ta.

    1. What kind of router are you using?
    Corega router at server side and Netgear DG834G on client side (with ethernet cable, not wireless).
    The Netgear works fine to other sites. The Corega is 'unproven' in that I do not have another site with same router. It can act as a VPN gateway (this does work elsewhere) but is not active in this role at this site (we want to use server vpn service).
    2. I have seen a few copies of 10.4.x Server just go
    L2TP/IPSec deaf. They all eventually sorted
    themselves out with software updates, but certain
    versions were just plain ol' deaf.
    I've now updated to 10.4.8. No difference.
    Just to reiterate...
    Port-forwarding of 500, 1701 and 4500 appears to be working, as a TCPDump on the server lists these packets when a remote machine is port scanning for them.
    However, the same TCPDump session does not list any UDP 500 packets when the VPN client (internet connect) is attempting to start. Logs show nothing beyond "listening for connections...". As I understand it, L2TP commences with an IKE communication on port 500 prior to the later 'real' stuff. Why is this not showing up in a TCPDump?
    Puzzled...

  • VPN Port-forwardinf & Passthrought

    Hi buddies!
    In my office we use a lots of VPN's from ours custumer and we had a lynksys e1200 with port forwardinfg for PPTP, L2TP and IPSec Passtrhought, right now we have migrated to a 2911 with CME features to manager SIP phones.
    I'm not and expert on the security area and withthe ISR we cannot connect to a customer VPN that uses PPTP (Windows) how can I make the portforwarding and passthrought on this new router?
    The interface Gi0/0 is to the ISP with NAT outside (PAT)
    The interface Gi0/1.1 is our LAN with NAT inside (PAT)
    I have integrate a the basic and lower default firewall that generates Cisco Configuration Profesional, but with or without this firewall we still cannot conect!
    Best Regards!

  • Ports 500 and 4500 are blocked

    Sometime in the past week, Verizon started blocking ports 500 and 4500.  This shuts down VOIP.  The Verizon agents I spoke to about this told me the only solution available would require my paying between $49 and $140 in order to get access to Expert DSL Technical Support.  I find this policy disappointing.  

    I understand ports 500 and 4500 to be for VPN, not VOIP?
    Either way, they should not be blocking ports out. Unless the ports are known dangerous ports. 
    Other carriers (primarily DSL) are starting to block these services. My personal opinion is so they can charge business rates for home users who may occasionally connect to workplaces securely.
    Just another poor business decision on their part.

  • Strange issue, I can't update my CS3 InDesign because it's being blocked by a QuickCam file

    My InDesign updates are not able to complete because its being blocked by a quickcam / logitech file ( QuickCam_11.90.1263\setup.exe ) - I've removed the file through Add / Remove programs, I've searched and deleated all quickcam / logitech files several times, then re-searcherd to confirm the files are gone and deleated from trash. However, each time I try to run the InDesign update the quickcam file is back.... after I deleted it?  It's like the InDesign update reloads it.  help!  I can find my way past this.

    Sounds like a virus. But probably isn't. Some software is probably re-installing it. Try removing the your camera from the computer and disabling any software that works with the camera, then reboot and try. If that doesn't work try a safe boot.

  • Ohio Alert System texts being blocked

    I subscribed to the Ohio Alert System to get text alerts for school delays/closings and they won't come through.  I contacted their support and everything is fine from their end.  They said another Verizon customer had the same problem and it was being blocked.  I emailed Verizion support and they said nothing is blocked on the phone to call them.  I just tried calling and there is way too much pressing this and that, say this and that, so I just gave up. Maybe someone here can help?  I don't have time to be pressing this number and to say what you need just to get through to support.  Thanks

    When I sent verizon an email the reply was that I didn't have anything blocked so that is why they wanted me to call.  Trying to get through all that click this and that number and all the other hoopla to get through was annoying so I gave up.

  • Port forwarding UDP 500 not consistent

    I have a WRT400N setup to port forward UDP 500 (IKE) to a VPN device on my LAN.  It works for a few hours, and then stops forwarding.  If I reboot the WRT400N, it starts forwarding again.  Has anyone seen this behavior?
    Other ports I'm forwarding, such as 443 (HTTPS) work OK all the time.

    Try to re-flash the firmware on your router and see if that works.
    Connect the computer with the Ethernet cable to the router.
    Download the latest firmware from Linksys website and save it on your computer. Open the setup page of the router. Click on Administration tab and go to Firmware upgrade sub tab. Browse the firmware file that you have already downloaded and upgrade it on your router.
    After upgrading the firmware on the router, it is recommended that you should reset the router and reconfigure it. Press and hold the reset button on the router for 30 seconds. Release the reset button and wait for 30 seconds. Power cycle the router and reconfigure it.

    IF that is the only iDevice activated for that recipient, then no. It should not successfully send as an iMessage if the phone is powered off or has no data connection. If you have Send as SMS turned on, it should automatically fallback to SMS after a few minutes. Of course, they won't get this until they power on their phone, assuming they have a text messaging plan with their carrier.

    All has been installed. Those are there in case you need to do a reinstall. Unlike most Windows based hardware vendors these days. Apple still ships software you might need in case a drive fails. Even in the case of the new MacBook Air, Apple ships the software on a flash drive.

    Hi shldr2thewheel,
         it has been a while since we have last spoke, I would like to let you know, I am still working on getting used to the switch from windows to a Mac/Apple system. I do have a new question for you, I did purchase In Design CS5.5 through journeyed.com through Cuyahoga Community College of which I attend as a student, is there a way to purchase an online book through iTunes to learn that as well? Also, you know me, the struggling student, I would also, when and if the book can be purchased through the iTunes, would need to know if you do know of a much easier book for struggling students like myself and at a reasonable price as well for the In Design CS5.5 program. Our campus bookstore had closed early, and, so did the colleges library and our local library here where I do live, so, I cannot go to either place to purchase a book or to take out a book, plus cash funds are low at this moment as well but, I do have money left on the iTunes account to use, if it can be used. So, can it be used, the iTunes money, towards finding a low priced online book? I am in great need of assistance as I have a project due for my one course for this Tuesday, September 4, 2012.
    Sincerely in need of help once again,
    Kim
