Hi all, please am submitting a CRQ for a simple static route via vrf
i.e.
ip route vrf  (vrf name) <ip address/mask> next hop.
I know it will not be approve if I did not put a statement about testing.
Please can anyone suggest any simple testing statement for static routing?

When ransomware hits your clients, what do you do?
When ransomware hits your clients, what do you do?

MSPs: Endpoint security isn’t enough to prevent ransomware.
As the impact and severity of crypto ransomware attacks has grown, Webroot fought back, not just by building a next-gen endpoint solution capable of preventing ransomware attacks but also by being a thought leader.

We decided not to spend that  60k/year on external consultants services to do scanning for rogue AP/SSIDs.

I noticed the consultant run a software tool on their laptop.  Any tool that could give a decent PDF report
certifying there's no rogue Wifi AP around will be most welcome.   Need something easy to use

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.

Hello,

I'm having some issues removing the start menu tiles in windows 10 through group policy on our 2016 windows server. I exported the start-layout xml file from powershell to use as the standard layout for all of our users in our group policy. Initially the users start menu will have no tiles as expected, but after a second login or so, there will be tiles from Dell.  Even after uninstalling all of Dell's bloatware, there's still a section labeled "Dell" but with no tiles.  Is there any way to make sure that no tiles will ever show?

Thanks!

What is the best option for a router or managed switch for a new fiber connection we have coming into our building?

Any recommendations other than a Cisco switch?

Basically we have a tail coming in with 50/50 fiber and 2 ip’s and 2 businesses need to leverage off it, our business and another.

Both businesses are separate but contributing to the connection and aside from QoS just need something to be able to push 1 internet ip to 1 lan and 1 ip to another.

Was assuming a managed switch or router with a vlan switch to 1 port and a vlan to another. Each business will have their own router and firewall from that point

No data can cross.

So was just looking for the best option and what unit would be reasonable whether a router or switch and just setup vlans

Any assistance greatly appreciated.

We have users that don't have static IPs and need them to gain access to some servers. They do have DDNS with nutpile so wondering if those dns names could be used instead of a source IP.

In this article I will be showing you how to subnet the easiest way possible for IPv4 (Internet Protocol version 4). This article does not cover IPv6. Keep in mind that subnetting requires lots of practice and time.

This article is amazing. I am studying for the Network+ N10-006 test right now and was able to use this information along to correct mistakes I was making previously in trying to determine Subnets and ranges of given IP address/CIDR on the practice tests. This makes it easier to keep the math simple in my head as well as to follow how to finish the resolution of the problem without reworking parts of the scenario. Great work and thank you for sharing it with us!

Our Windows 10 computers request WiFi RADIUS machine authentication continuously (every few minutes). We see this in the logs of our RADIUS server The logs are filling with re-authentication requests.
The WiFi profile is applied by group policy.
Power save modes have been disabled.
Has anyone else had a problem like this?
Thanks for your help.

Hi.  We have Scom monitoring two domains.  (Two way trust)

All seems fine but early days

I need a report that shows uptime it availability of active directory in domain B


What I can do is use the standard availability report. Agains the ad topology object    Works but it shows both domains.  Not just the one I want

Any ideas how to focus this to one domain please ?

Looks like the re-seller sold us network gear (routers, firewalls, switches, controllers) without any manufacture or 3rd party support.  Probably cost effective that way.  Now they getting me a support quote.  Tricky?

Questions.  Can they do it normally?  And does it mean I wont have any support even day 1 after installation?

This is in US and licensed large certified reseller.  Network gear, Cisco/PAN.

Everyone has always said HUBs are bad and send information to ALL devices

I have an employee that needs another PC setup next to them ASAP and I do not have time to run another 100' CAT6 cable from the switch to this PC, therefore I just setup a small $10 cheap hub as follows

 1. patch cord from SWITCH to HUB
 2. patch cord from HUB to PC #1
 3. patch cord from HUB to PC #2

Which one of the below options will happens since a HUB is now in the mix when PC #2 updates a file on the Windows 2012 R2 file server since I did not wire back to the Cisco switch ?

    ** Option #1 = PC #2 sends info to ALL 100+ devices on my network, with only the file server accepting the data

    ** Option #2 = PC #2 sends info to ALL devices that are plugged into the hub (i.e. only PC #1 and the switch), with only the file server accepting the data

   ** Option #3 = something else ?

Hi All

I have a couple of clients with SonicWALL TZ 300 routers, and am considering having them purchase SonicWALL’s Capture Advanced Threat Protection because it seems like a damn good idea! As I understand it, it's cloud based sandbox system.

Would appreciate hearing everyone's thoughts, concerns or experiences with the product or similar products.

Thank you!

I have  router R1 connected to router R2.
R1 has some loopbacks and the networks that the loopbacks are on, are advertised to EIGRP

R1 has some Networks(172.16.0.0 0.0.255.255) that I need to filter out, so that they do not end up in R2 routing table:
on R1 , I have created Route Map , but before even I specify anything in Access-List and make route map match the Access-list . I have found that the Network 172.16.0.0 has already  been filtered out from R2 routing table... I wonder what has filtered it out .



R2(config)#do sh ip route | inc 172.16
R2(config)#

you see there is nothing about 172.16.0.0  in R2
Thanks



R1(config-route-map)#    do sh ip interface br

I have a Sonicwall NSA 3600. I have a block of Public IP's.  I have a Server 2012 vm with two IIS sites and two seperate LAN IP's configured in bindings.  One of the IIS sites has been configurd in the NSA via the wizard. The Address Object is called "web1."  

When trying to run the web server wizard for the second IIS site, i get error "Server name conflicts with existing address object" when entering the same name of "web1" which is the servers DNS name.  I change the name to "web2" and assign my LAN IP and my seperate WAN IP and it completes the wizard and creates rules.  

However, my site is not available at all. Not even by WAN.  I ensure i configure private and public DNS but it wont resolve.

Has anyone seen this issue when running to web sites from one server trying to create the firewall rules in an Sonicwall.

Free Tool: Port Scanner

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

People moving into the new office but the network gear may not be ready yet.  Looking for a quick alternative for WiFi access just so users can go online.  
Saw that thread below from 2015 where a person says they ran office of 30 off this device following hurricane Sandy.
My office would be about 10-12 people day one.

Would that work as a temp solution?  Any suggestions appreciated.  Thanks!!

I need to add a route to our ProCurve switch which will allow all traffic from my network destine for a network in our parent company.

All traffic from 192.168.0.0/21 going to 172.20.0.0/16 needs to go thru (edge router)192.168.0.150

My parent company sent me the edge router and setup a VPN tunnel using this device, which has the 192.168.0.150 interface. The VPN is working as If I add the command  "route ADD 172.20.0.0 MASK 255.255.0.0 192.168.0.150" to my computer I am able to reach the server at our parent company.

Not sure how to add the route to the ProCurve
 

Below is the config for my ProCurve

hostname "ProCurve 2910al-24G Switch"

I am trying to understand the purpose of the number that comes after the "/".
example:
ip prefix-list TEST seq 5 permit 10.0.0.0/2 ge 17

2 means match 2 bits of first octet 10

however whatever I put , the prefix list will care just about the ge 17

to clarify it I have this table before filtering:

R1(config)#do sh ip route 
      10.0.0.0/8 is variably subnetted, 6 subnets, 6 masks
D        10.1.0.0/16 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.2.0.0/17 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.3.0.0/18 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.4.0.0/19 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.5.0.0/20 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0
D        10.6.0.0/21 [90/156160] via 192.168.12.2, 00:00:01, FastEthernet0/0

Open in new window


if I use : ip prefix-list TEST seq 5 permit 10.0.0.0/2 ge 17
router eigrp 1
 distribute-list prefix TEST in


R1(config)#do sh ip route

      10.0.0.0/8 is variably subnetted, 5 subnets, 5 masks
D        10.2.0.0/17 [90/156160] via 192.168.12.2, 00:00:03, FastEthernet0/0
D        10.3.0.0/18 [90/156160] via 192.168.12.2, 00:00:03, FastEthernet0/0

so what 's the purpose of the number that comes after the slash sign "/", example:10.0.0.0/2

Thank you
