We describe how to allowlist (formerly known as whitelist) source IP addresses to prevent Silverline Routed DDoS services from mitigating / blocking them.
- Source IP addresses are allowed as exceptions from being potentially blocked by Silverline.
- Even if the client attached to a allowlisted IP address is marked as suspicious, the client is allowed to bypass the DDoS mitigation logic and permitted to transit to your servers.
- You can allow IP network prefixes to bypass mitigations.
- NOTE: The AllowList functionality in portal does not bypass your GRE firewall rules. Firewall ACLs run independently of the mitigation filters and are under customer control.

- Silverline DDoS
- DDoS IP Allowlist
1. Navigate to Config > IP Management > DDoS IP Allowlists
2. Select the +Add button in the upper right.
3. Enter up to 100 IP addresses or IP prefixes, one per line.
- An IP address is entered in the normal four tuple format.
- An example of a prefix would be: 18.104.22.168/24 - This would block any address in the range 22.214.171.124 - 126.96.36.199.
4. Click Save.
Important note: It is recommended to redeploy the L7DoS profiles to use updated Allowlist.
