This module provides an updated list of Duo's public CIDRs. These are maintained against the Duo Documentation: https://help.duo.com/s/article/1337
This module provides an updated list of Duo's public CIDRs. These are maintained against the Duo Documentation: https://help.duo.com/s/article/1337.
Supported on both Terraform and OpenTofu.
# Usage
```hcl
// Import the module
module "duo-ips" {
source = "captn3m0/duo-ips/data"
version = "1.2.0"
version = "1.3.0"
}
// Allow traffic for MFA APIs for all region CIDRs
// Also open traffic from these to your LDAP Server port 636 if you're using LDAP
resource "aws_security_group_rule" "allow_all_to_duo" {
type = "egress"
from_port = 0
to_port = 443
protocol = "tcp"
cidr_blocks = ["${module.duo-ips.cidr}"]
type = "egress"
from_port = 0
to_port = 443
protocol = "tcp"
cidr_blocks = ["${module.duo-ips.cidrs}"]
security_group_id = "sg-123456"
}
// Limit MFA traffic to specific regions
resource "aws_security_group_rule" "allow_all_to_duo_uk" {
type = "egress"
from_port = 0
to_port = 443
protocol = "tcp"
cidr_blocks = ["${module.duo-ips.uk-cidrs}"]
security_group_id = "sg-123456"
}
// trusted endpoint requests are made from these ranges
// depending on what port your origin is using, pick the correct port here as well.
resource "aws_security_group_rule" "allow_all_from_duo_in_ingress" {
type = "ingress"
from_port = 0
to_port = 443
protocol = "tcp"
cidr_blocks = ["${module.duo-ips.trusted-endpoint-india-cidrs}"]
