# Alternative Ingress IP
This feature allows you to configure the Algo server to send outbound traffic through a different external IP address than the one you are establishing the VPN connection with.

#### Caveats
##### Extra charges
- DigitalOcean: Floating IPs are free when assigned to a Droplet, but after manually deleting a Droplet, you need to also delete the Floating IP or you'll get charged for it.
##### IPv6
Some cloud providers provision a VM with an `/128` address block size. This is the only IPv6 address provided and for outbound and incoming traffic.
If the provided address block size is bigger, e.g., `/64`, Algo takes a separate address than the one is assigned to the server to send outbound IPv6 traffic.
