Protect Your Google Cloud Instances with Firewall Rules

Moving from on-prem to the cloud can bring a ton of new features for your applications, but one of the biggest challenges is how this movement can expose your systems to new vulnerabilities.
In this video, Stephanie Wong shows you how to control traffic in and out of your instances on GCP by creating Firewall Rules.

Thanks Michael!

[@spoown007]

and boom, nice demo !

[@timmybabson8218]

nice video.

[@sureshiam8350]

is it possible to block the ssh/rdp traffic through IAP unless the traffic comes from a specific network subnet? Please advise.

[@haribolanil]

You are awesome guide

[@phillyeagles0728]

You added an ingress rule to both VM's, but shouldn't you have added a similar egress permission on port 5001 on the first VM to allow outgoing iperf? Or when you said "allow Egress" default rule, it means allow all outgoing by default upon VM creation?

[@stephaniewong142]

Every VPC network has two implied firewall rules. These rules exist, but are not shown in the Cloud Console:
Implied allow egress rule lets any instance send traffic to any destination. Implied deny ingress rule protects all instances by blocking incoming traffic to them. cloud.google.com/vpc/docs/firewalls#default_firewall_rules

vpc firewall refuses to open any ports i try to open

[@celinfigueiredo]

I've made new rules, but not working. Where do i fount help?

[@titobundy]

How can I connect two instances, one in default network and the other in a custom vpc? , I tried to ping in each instance to other but unsuccessfully, booth networks have the firewall rules icmp active

[@stephaniewong142]

Make sure you've allowed ICMP for traffic from the public internet 0.0.0.0/0 or the subnet range of the other network, or use target tags on your instances and apply firewall rules to the tags. Ingress firewall rules that use source tags can take time to propagate. I'd also recommend using Network Intelligence Center Connectivity Test to have a visual way to test configuration and verify connectivity between instances. th-cam.com/video/edwa3cW6s-Q/w-d-xo.html

But how can I save my bluram cam to google iCloud

[@RajKumar-vd3iq]

If i create a new instance and add this VM to our custom VPC the is Iperfaccess traffic automatically allowed for this VM, If yes how can i restrict to the particular VM. Please reply,

[@stephaniewong142]

Create a new firewall rule that only allows TCP: 5001 traffic from the specific source IP range your source VM is sitting in, instead of the public internet, or apply the firewall rule to a source tag and apply the tag to the source VM instance.

How to block contry wise

[@andersonmora769]

We need geoip in firewall rules, define ranges is exhaustive.

[@rvwoens]

this assumes you already have created instances on a created VPN. No information is given how to do that

[@user-rr7yi3ru2p]

it shows me: You do not have sufficient permissions to view the networks in this project.
