Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

I am looking to create an IP strategy for a hybrid environment (VMware on prem and Azure public integrated). I am wondering if anyone has best practice on best practices for IP strategy and more importantly on IPv6 implementation in Azure. Anything to watch out for with IP addressing, in particular IPv6.

Your help is appreciated.

What types of daily/weekly/monthly activities are require to effectively manage a SAN device? I appreciate this is very generic, but often organisations use a 2nd SAN as a repository for disk based backups, so having some assurances from a management perspective that this DR SAN is well managed/maintained/monitored is quite important.

Also from a contingency / support angle, what sort of arrangements / contingencies should you look for in terms of support if there was a failure of the entire device or a core component?

Our Solarwinds admin guy said he can't set up rules unless a sample event is sent to solarwinds.

We have about 70 events from an app : so far the apps team only could get someone to login/logoff
to simulate once such event but for the other 69 events, need to do reboot etc which they can't
unless there's downtime.

Attached is the full list of snmp events our apps team gave to me.

I'm wondering :

a) what exactly our solarwinds admin is expecting or hinders him from creating rules?  He's
    elusive & extremely busy (ie no time to show me)

b) are there free tools like snmpwalk etc which I could trigger sample events?

I'm sure Cisco devices & Windows events which are currently sent to the solarwinds will
go through the same process to be monitored but really doubt the network chaps will
send the 100+ Cisco event types to Solarwinds for them to be monitored.

looking for some sort of checklist or ideas in terms of criteria in which to critically appraise the performance of our IT service, which is partially in house and certain functions outsourced. I know there are obvious areas such as time to resolve incidents/service requests, uptime of critical apps etc. But was hoping if you work in a contract monitoring type role where you outsource certain IT functions if you have any criteria in which you audit/assess the relevant team against.

i Have an unregistered NSA240.

Setting up two LANs both trusted but cannot route between them also on second LAN, management not allowed.

Is this do to the device not being registered?

Cannot remember having this problem before.

Looking for some advice here....

About a month ago we sent out a notice to our customers that we would be moving our SAaS service from our hosted data center to the AWS cloud.  The weekend to do teh migration is now here and we have run into an issue migrating data that will give us reason to believe there is a chance that the site may not be ready Monday morning when we are supposed to be ready.  The management team here is saying that there is no way we can send out a notice delaying this migration.  I am requesting we give the customers notice that the migration will be postponed.  How bad does postponing the migration look?  How does it compare to having real problems on Monday if it does not go as planned?

I have been using SonicWall for years. Never really thrilled with their support (primarily a language barrier until recently) but their content filtering seems to be problematic. I spend more time on the phone with them trying to keep it running correctly than it is worth.

Does anyone else use SonicWall for content filtering and in your opinion is it easy to keep running? Any comments about sonic wall in general?

Hello All,

I have an outside vendor that needs to communicate to their equipment on our inside network. I would like to set up a DMZ for that access. I have 5 public IP addresses to use. The ASA i want to set up is strictly for this use and no other. I have four devices on the inside that will have static IPs which will require certain ports to be opened. This is what they require. I do not have a config to post as of yet. I am trying to configure one.

Four static private IPs
External port forwarded to internals
  Port 90 Open - 1st internal IP
  Port 91 Open  - 2nd internal IP
  Port 2048 Open - 2nd internal IP
  Port 92 Open - 3rd internal IP
  Port forward 2049 to 2048
  Port 93 Open - 4th internal IP
  Port forward 2050 to 2048

Any suggestions would be greatly appreciated.

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.

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.

Hi Guys

I need to find a way to allow the 10.0.0.0/24 network to be reached from 10.10.1.0/24 – 10.10.3.0/24 networks. Given little documentation, I need the help to allow for communication between the networks, trying to achieve the below (sorry, I know it is sketchy)
 
10.10.1.0/24 >>> PING >>>> 10.0.0.0/24
10.10.3.0/24 >>> PING >>>> 10.0.0.0/24
 
10.0.0.0/24 >>> PING >>>> 10.10.1.0/24
10.0.0.0/24 >>> PING >>>> 10.10.3.0/24

The below is .conf file I pulled from our OpenSwan 2.2.6, this .conf file is for our 10.10.1.10/24 network (the 10.10.3.0/24 network is similar)
 
conn ifly-pen
        auto=start
        type=tunnel
        left=%defaultroute
        leftsubnets={172.17.0.0/16 10.0.0.0/24}
        leftid=54.153.249.30
        right=115.70.193.138
        rightid=115.70.193.138
        rightsubnets={10.10.1.0/24}
        authby=secret
        ike=aes128-sha1;modp1024
        esp=aes128-sha1
        pfs=no
        forceencaps=yes
        force_keepalive=yes
        keep_alive=10
        ikelifetime=8h
        keylife=8h
 
You can see, the leftsubnets allows for communication to the 10.0.0.0/24 network from the 10.10.1.0/24 network. However, in the 10.10.1.0/24 network, when I ping the 10.0.0.1 IP address I get no response, see Ping.png and Tracert.png
 
Our OpenSwan IP is 172.17.0.6 and it is a VM in AWS, you can see the above is routing through the 10.10.1.1 (on the 10.10.1.0 network, router), through to the 172.17.0.6 but then goes …

switch model: Aruba 2920 48G POE+

Adding to a stack which already has 3 switches. Is it just a matter of reordering the stacking cables or is additional config required?

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.

It should satisfy the following conditions:
1. Capable of 75Mbs bandwidth
2. Up to 25 users
3. Its VPN client must flawlessly work on all client machines including Linux and all modern Windows versions.
4. Costs less that $500

Currently we use a Sonicwall TZ170, its maximum bandwidth is just 25Mbs

If I configure sonic wall tz300 to get WAN ip from Comcast GW DHCP, will I still be able to configure the VPN for remote access?   I am mulling several different topologies, and if this could work this seems like the easiest way.

I am setting up a small business network.  DNS and AD is being managed on Win Server 2016.  Should I have Windows Server manage DHCP as well?  I was thinking about having a sonic wall fw manage DHCP, VPN.  

If I want remote users to connect to the vpn authenticating with domain credentials, does this sound right? Any suggestions on Network Topology?

Because SNMP uses two different port numbers (UDP ports 161 and 162), a single system can easily run both a manager and an agent.  What would happen if the same port number were used for both?

Wanted to see if anyone had any knowledge regarding providing 4G LTE as a backup line for an enterprise office.
I was investigating some Cisco / Meraki options, including :

- Cisco 890 series ISR
- Meraki router + Inseego (formerly Feenet Wireless) Skyus DS

Would anyone have any info or experience with one of these as a solution for a temp situation or as a backup solution.
Appreciate in advance.

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 ?
