SQL Windows Firewall

I set up a lot of SQL servers. Here are the powershell commands to allow the sql ports. Please don't be 'that guy' who shuts off the firewall.

New-NetFirewallRule -DisplayName "SQLServer default instance" -Direction Inbound -LocalPort 1433 -Protocol TCP -Action Allow

New-NetFirewallRule -DisplayName "SQLServer Browser service" -Direction Inbound -LocalPort 1434 -Protocol UDP -Action Allow


You can also do it with netsh in DOS.

netsh advfirewall firewall add rule name = SQLPort dir = in protocol = tcp action = allow localport = 1433 remoteip = localsubnet profile = DOMAIN


netsh firewall set portopening protocol = TCP port = 1433 name = SQLPort mode = ENABLE scope = SUBNET profile = CURRENT

How to set up a Site to Site VPN on AWS to your firewall

 AWS VPN-

1) First you need a "VIRTUAL PRIVATE GATEWAY"- this is the connection to the on-prem firewall. Use the amazon default ASN, that doesn't matter. Once you create it, attach it to the VPC. You only need one of these for all VPNs.


2) Next you go to Customer Gateways, don't worry about the BGP stuff. IP address is your firewall IP. Leavn certification blank.


3) Go into site-to-site VPN connections, create it and tie it to your virtual private gateway, select your existing customer gateway you created, set the routing option to static, static IP prefix is your remote lan. Leave local and remote IPv4 blank.


4) You will need to add routes in the route table. Create a route, point it to Virtual Private Gateway and select the gateway. 


5) You will need to allow access in the security groups from your on premise servers.


6) Once it completest, click download configuration to get the info for the local firewall.
