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.

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?

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

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

[RajKumar-vdiq]

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,

vpc firewall refuses to open any ports i try to open

[rvwoens]

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

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

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