We have 2 internet providers, one for data and one for voice. We have a firewall and a HP L3 switch (HPE 2920X). We are using RIPv2 to inter-VLAN as we have multiple VLANs setup in the environment.

We have 5 VLANs setup, and one of them will be voice which has its own internet gateway. Our firewall is connected to Port 1 of the HP 2920 switch, and the voice router is connected to Port 48 of the HP 2920 switch. On the phones and the PABX system we have given the voice default gateway, and the LAN/servers/printers etc are given the HP 2920 default gateway using DHCP.

All seem to be working,however the calls are dropping out and getting a message "No route to destination". Im just thinking it might has something to do with the routing or the  voice PABX/internet issues. Because they are inter-connected, we added ACL rules to block traffic from voice subnet to subnets.

Can anyone share some lights?

Many thanks in advanced.

Hello EE,

Our VPN firewall prevents ipV6 (blocks) so our Visual Studio debugger is failing to connect.
I wonder if anyone knows of a way in Visual Studio to turn off ipV6 and only use IPv4.

I upgraded my manager's computer to Windows 10. The manager has at least 50-60 desktop web links. Now in windows 10, each web link take 20 - 30 seconds t load the page. I have reset IE to defaults, changed the default browser to edge (the links still open in IE). uninstalled / reinstalled .net4. Set the file explorer to defaults. no add-ins. Can't figure out the issue.

I get error below...

I was working earlier today.

Can not  access from any chrome and firefox as well.

TLS 1.0, TLS 1.1, and TLS 1.2 is already turned on in IE. Tried removing it and adding back in but no luck.
Server is : Windows Server 2012 R2

Error below

This page can’t be displayed


Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://www.virginaustralia.com  again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure. Please contact your site administrator.

The proxy server would always get reset to (127.1.1.1) port 8003 in IE and if you manually set it back to no proxy and delete the line item out on a restart it will automatically re-enable itself. We do not use a proxy server and this address is not a valid one. I did read online about it: (http://deletemalware.blogspot.com/2014/12/remove-proxy-settings-127001-hijack.html)

followed the steps but after a reboot it will always come back.

Thoughts>?

Visited a client site and ran various ‘my ip address’ site to determine what is the External IP address the provider assigned.  Noticed that each device resulted a different value.  For example their phone and their tablet gave different values where that last segment changed (xxx.xxx.xxx.19 and xxx.xxx.xxx.20), yet when we ran myipaddress in our device gave a whole different value in all segments.

We understand that the internet provider assign the cable modem or location a single dynamic external ip.  The location router managed a total different internal ip sequence values and assigns it to each device connecting to the wifi or router within the location.  Thus the cable modem has 1 IP address and the devices within the location has different ip address.

Why would the “my IP address” website display different IP address in all devices connected to the same wifi?

When I do a Google search in my own language (Swedish), using www.google.se and advanced settings where I have selected to only display search results in my own language, it doesn't say that the search results are in the Swedish language. Earlier this was always displayed (something like "Only display search results in Swedish").

What has happened, and how should I solve this so I get search results in Swedish in Google again?

I use Google Chrome on a Windows 7 Home Premium.

It is the same thing in Internet Explorer also.

Around the time some of our traffic dipped to our site - I saw a number of changes of BGP path with lots of prepended AS's indicating less preferred routes. If those changes were beyond our directly connected ISP, what is the best way to find out why the path changed at that time? Is there a way to find out? There were perhaps 10 path changes in 10 minutes before things got back to normal.

Hi there!

I have a development written in .NET/C# standard (not .NET Core) that connects to a Rest API for fetching records of my customer's business. In other to login I have automated sending login form using NHtmlUnit, when I get an authorization token, I use RestSharp for fetching the data. The program runs well when I run on my development machine, however, when I deploy the the production environment (in this case, Azure), I get the following exception exception:

I recently started with cable internet service after being with FIOS.  Maybe the drop from the pole is pre-existing.  

There's the lightning arrester then the cable comes right into the house into a netgear CM 400 cable modem that I bought (it was cheap and says it was docsis 3 compatible which is what the ISP says I need.

Things working great for a couple months.  Then in the last week, I get loss of internet for 15 minutes or so at a time, then it comes back for 1/2 day - 1 day at a time.

Cable company came out and added a 6db attenuator, checked connections.  Said signals look good.


But still having these dropouts and error messages in the modem event log. Cable company says they don't do anything with modems that aren't theirs / don't know what these errors mean.

Any advice? I am going to pop for their modem rental $5 / month, but is that the answer or is there a problem with their network / cable drop?

See the 2 screen captures of the up / down.  A load of errors in the right most columns., right?

the event log:

We have AT&T MIS 10Gbps Ethernet circuit with speed throttled to 2Gbps. We have 10Gbps fiber connection from AT&T router to our fortinet firewall 600D 10G port. Is their a way to test internet speed over 1Gbps? We don't have any device or NIC with more than 1 Gig. How to test it?

Hi

I'm going to file my blog trademark again. Lame, but I neglected to do the final step one time, because I was so annoyed with the seeming endless ( unstoppable) billings. It felt like a Nigerian scam. Truly, I was suspicious and concerned.

Anyway, forget about it. I'm going to file again and there are 3 options. Does it matter which one I use? - for a blog name trademark? Also, would a logo filing be done later? The costs are complicated?  What will they be?

This is the initial page - notice the feeling-to-be-never-ending fees,      here

Thanks

I have a Synology NAS Server with a 500gb Hard drive connected and a Nvidia shield TV box/console.
Both the devices have the PMS (Plex Media Server) installed.

What I want to do is watch IPTV through plex. Ideally I would like to have the IPTV installed on the PMS that is on my Synology NAS Server as that is on and running all the time,  so that I can watch IPTV on my android phone when out of the house.

Does anyone know where to manually find the plugin folder on the Synology NAS Server or if not on there then where the plugin folder is on the Nvidia shield TV?

Also, can anyone recommend a stable IPTV channel for plex which I can use to load the IPTV playlist m3u?

Thank you...

Dear Team, we are suffering the slow problem of Email Exchange 2016: Send from Exchange server is OK, but receive is slow; which ever have or does not have attachments.

We have Avast installed in Exchange server, everything in default mode, not sure which Exchange part should be added to AV's exclusion.

Is there any other way for tuning or increasing the speed (except increase the bandwitdth, we are in Leased line link: 30 Mb/s International + 50 Mb/s Domestic)?

Many thanks as always!

I have fortinet 600C with WAN interface connected to AT&T router (1 GigE). We are in process to upgrade AT&T MIS circuit from 1Gig to 10Gig. The speed is going to be throttled to 2Gig. What are my options with Fortinet 600C to get 2Gig link speed? Do we have to get two cables going from AT&T or we have to replace the fortinet? What is recommended or what should we do?

I have about 30 000 files which are a mix of jpg, png, mov, mp4 and potentially others.  Total size is around 70GB.  I've collected these into a single folder structure and left an upload to google photos running, and then used the desktop uploaded and left that for a week to upload any that were missed.

Now, I'm not sure which have uploaded successfully and which haven't.  The 'log' created during the upload is not helpful when working out which files haven't uploaded.  I've done a download of the photos from google photos through their backup system.  However, I can't just windiff between the two folders as they have different subfolder structures.  I've tried doing an xcopy of files to a single folder but some of the files have the same name (although different dates) and I may miss out on file-extensions that I'm not aware are in the listing.

Does anyone have any ideas or scripts I could run to make the problem easier to solve, or to come up with the final list of files that haven't uploaded?

I have a 2012 R2 IIS 8.5 Server that is running a web site for the application Kaseya.  I am trying to lock it down so depreciated ciphers are disabled and I would like to reorder them in a more secure fasion.  I have attempted to make the changes to the schannel key in the registry (didnt Work).  I have used Narcos IISCrypto and I have ran Powershell scripts to try and recreate all my keys.  I also used group policy to decide the cipher order.  Nothing has worked.  No matter if I have every cipher disabled or even protocol, they still show that they are in use.  I am scanning the server using Qulays ssl scan.  Has anyone ever ran in to this issue?  I have had no problem doing this on other application web servers in my organization, but this one seems as if the protocol and ciphers settings are hard coded somewhere other than the registry.  Any ideas would be greatly appreciated.  I'm wondering if the web application is forcing it somehow and my registry settings have no effect.  I just have never seen this happen, nor can I find any reference on the internet.    Just so everyone is aware, I have restarted after making the reg changes.  Unfortunately, the same protocols and ciphers are always enabled.

My computer is Windows 10 latest update, ASUS laptop using a USB to Ether adapter.
I plugged my computer into the router but I am not getting Internet. Can someone help me fix/diagnose this problem? I can get access using the wireless but that is very weak signal and not consistent, so I want to connect by wire.
Thanks
