Hi,
 
 I have a windows 10 PC (domain joined on Windows 2008 network) that I can ping it by IP address neither by IP address nor by name.
 But that computer can connect to the internet, domain, mapped drive ... everything works normal from that computer, including I can connect to that computer using Splashtop remote software too from outside of the network.
 I discovered this weird situation when I failed to RDP into that computer. First I ran firewall.cpl and made sure that REMOTE DESKTOP was checked for domain, private and public.
 I went to the domain controller and confirmed that IP address and computer name was registered in DNS manager and DHCP server. Other workstation computers can ping each other by computer name and IP address.
 What can I do to troubleshoot this issue?

Thanks.

Dear Experts，

I have a set of fortigate firewall policies which I need to duplicate on a cisco router.

I have done most of the point A to point B.

The issue I have now is the NAT and there is an IP Pool, is there a guide on how I can translate the rules from firewall to cisco router?

Any help is appreciated.

Hello,
I am deploying pfSense firewall following the topology bellow:
My Network Topology : Router + pfSense + FW1 (Router connected to Internet) + Internet Service Provider + Internet WebsiteWhere FW1 is a router connected to Internet using a leased line connection, and pfSense firewall is located in a BACKBONE network, different as users networks.
I add too, that this is a new setup of this firewall, and connectivity in both sides is verified, i mean:
  • Connection to internet : i was able to download new package SQUID/SQUIDGard from Package Manager
  • Connection to the LAN : i can access firewall from  my pc, and i can see SQUID error message, when i try to open a website
The problem now, I want to grant PC IP address authorization to access Internet. I created a RULES for both HTTP and HTTPS protocols, but i still cannot access Internet.
And the firewall, says that i have not the right to do so.
I'd appreciate any help from you Experts.
Regards.

I have been using an Excel 2016 VBA program that uses XMLPRC to upload some documents to a website.
This program has been in use for a number of years now, but it has just started to fail on my Windows 10 machines.

I see some messages in the Security Event log saying that the The Windows Filtering Platform has blocked a packet. Event ID 5152
I have added Excel to the Firewall, but doesn't seem to change.
The Windows Filtering Platform has blocked a packet.

Hi All,

I need some assistance setting up the below. I've got 3 "subnets" to set up internally. All must be able to reach the internet through the suppliers router.

The networks are 2x /26 and 1x /27. VLANS 601 & 603 are desktop pc's. VLAN 602 will be Cisco phones. 601 and 603 do not need any seperation, they're just to cover the seperate DHCP ranges. DHCP will be provided by an external source (hopefully) through a VPN setup on the ASA Firewall. I'm looking to setup outside interface, inside interface and access for all vlans.

Is anyone able to provide a sample config on how I could get this working?

Network Overview
Thanks,

J

Problem with customers sending/receiving documents from server, running SolarwindServer har returned after Windows Update
After Windows Update port 22 i closed
If I stop the windows firewall, I still have the issue and according to traceng, port 22 is close even if firewall has been stopped
I only have a firewall setting for inbound port 22 (see attached files)

My hosting company solve the issue - they ask if there is an update avaiable for Solarwind SCP Server ver. 1.0.4.9?

What is the best way to communicate between a Windows Service application and a UI Application within the machine.
Currently I am writing into a SQL lite database and reading every second in both applications.
My Service application has Socket Communication for inter machine, I do not want Sockets on UI (to avoid Firewall blocking).
IPC at times gives problems when the users are different (Local System and Standard user)
I use Delphi Seattle on Windows

Hello Experts,
Just wanted to find out how do you guys dynamically update the Office 365 endpoints IPs and URLs that are published by MS for the proxy and firewall access? I know the RSS feed will be retired soon per what I read online and do you guys just run a PS script that grabs the info from the published XML file or there's a better solution/idea out there? Any input would be greatly appreciated!
