#* The <i>Remote</i> text box should automatically have <i>CIDR</i> in it; do not change this.
#*In the <i>CIDR</i> text box, replace <code>0.0.0.0/0</code> with <code>your-ip/32</code>. Note that this is the IP address of the physical computer you are wanting to use to connect to your VM. If you don't know your current IP address, you can see it by going to [http://ipv4.icanhazip.com ipv4.icanhazip.com] in your browser. If you want to access your VM from other IPs, you can add more rules with different IP addresses. If you want to specify a range of IP addresses use [https://www.ipaddressguide.com/cidr this tool] to calculate your CIDR rule for a range of IP addresses.

#*<b>Do not remove the default security rules</b> as this will affect the ability of your VM to function properly (see [[Managing_your_cloud_resources_with_OpenStack#Security_Groups|Security Groups]]).

#*<b>Security rules cannot be edited</b>, they can only be deleted and re-added. If you make a mistake when creating a security group rule, you need to delete it using the ''Delete Rule'' button on the far left of the row for that rule in the security groups screen, and then re-add it correctly from scratch using the ''+Add Rule'' button.

#*If you change your network location (and therefore your IP address) then you need to add the security rule described in this section for that new IP address. Remember that when you change your physical location (example working on campus vs working from home) you are changing your network location.

Remember that when you change your physical location (example working on campus vs working from home) you are changing your network location.
#*If you do not have a static IP address for the network you are using, remember that it can sometimes change, so if you can no longer connect to your VM after a period of time sometimes it's worth checking to see if your IP address has changed. You can do this by putting [http://ipv4.icanhazip.com ipv4.icanhazip.com] in your browser and seeing if it matches what you have in your security rule. If your IP address changes frequently, but the left most numbers always stay the same, it could make more sense to add a range of IP addresses rather than frequently modifying your security rules. Use [https://www.ipaddressguide.com/cidr this tool] for determining a CIDR IP range from an IP range or learn more about CIDR notation [https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#CIDR_notation here].
