Ubiquiti VLAN with current setup.

As of right now there’s only one VLAN, VLAN 10. What can I do to create another VLAN, VLAN 20
VLAN 10 IS 172.16.1.0/24 We want VLAN 20 to be 192.168.1.0/24

All computers in VLAN 10 have internet access, all is working perfect, the DNS and DHCP server is 172.16.1.20

I noticed that the unifi siwtches only let me create a vlan name, nothing else, the VLAN 20 is already created on the Cisco switch, but the Unifi Switches don’t see it.
What do I need or doing wrong?

We have a computer who is accessible by placing '\\pc-name\j$' in the Windows Explorer. We also have that same location mapped using the command 'net use j: \\pc-name\j$'.

When in the command prompt we use 'Dir \\pc-name\j$' or 'Dir J:\' works excellently - total access.

However, if place 'J:\' in the Windows Explorer or if we type 'start.', in order to open explorer at that point, it gives the following error:

How can we successfully use Windows Explorer to access this 'J:\' ?

Israel Internet

I'm at a client which has an Internet feed from their Israel office which egresses in NYC. Nobody seems to know why it was put in that way. Might any experts on here with middle east experience know why you might want to egress on the other side of the Atlantic rather than just using a local ISP? Or at least Europe? Security issue? Tax issue? Something else??

How to use BGP Default Local Preference

Screen-Shot-2017-08-06-at-11.30.59-A.png

on the topology above , I have R1 and R6 on AS 1, R5 on AS3 , R2,R3,R4 on AS2

I would like to have Routers on AS1 (R1 and R6) Not take route through AS3 to reach routers inside AS2, instead I want AS1 routers to go straight to AS2 through R1 using BGP Default Local Preference command on R1

you can see in the config below on R1 :
bgp default local-preference 600

Below is the BGP route configuration on R1, R6, R3. As you can see R6 is going through AS3 to reach routers in AS2 instead of going straight to AS2 through R1

If you need more info , please feel free to ask.

Thank you

What is the process to logon to or reset the logon username and password for a SonicWALL TZ600 router when the logon information isn't known?

We don't want to reset any information on the router we simply want to logon to it or reset the username and password.

We have physical access to this router.

How can this be done?

Network switch question

Hi experts,
i need some advice. i have about 50 pc's on our company network with 1 file server that these pc's access for AD,DNS, DHCP and our financial application(uses access database). we currently have a 48 port 10/100 switch with 2 gigabit uplink ports as the backbone and then 2 gigabit switches connect to this backbone switch. i was aiming to replace the 10/100mb backbone switch with a full gigabit switch but budget is a problem at the moment. would the following work as a temporary solution for about 3 months: I will install a very entry level 8 port dlink gigabit unmanaged network switch as the backbone, connect my server and links to other switches to this 8 port switch. so from the 8 port switch i will connect all 4 network cards on my server to this switch as well as the link cables from my 3 larger switches. I know this is not the best solution but i just need something that will do the job for a few months? or would this small 8 port switch take too much strain?

symantec/veritas backup exec settings

can I ask a few basic questions in relation to Symantec backup exec.

1) what is the underlying database which stores all the configs, e.g. sql server or something else?

2) where is the management console can you see which accounts are authenticated for access? is access based on windows logins or accounts specific to backup exec?

3) in terms of the management console configuration, what needs to be backed up?

4) and is there an easy way to export all the current settings, e.g. jobs/schedules, backup selections per server (e.g. which drives) alert configurations and recipients, out to a single file for offline analysis?

5) is it application aware, e.g. by default does the standard package have the ability to backup exchange, SQL, AD, sharepoint etc.
