# This is the list of users to generate.
# Every device must have a unique user.
# You can add up to 65,534 new users over the lifetime of an AlgoVPN.
# User names with leading 0's or containing only numbers should be escaped in double quotes, e.g. "000dan" or "123".
# Email addresses are not allowed.

### Review these options BEFORE you run Algo, as they are very difficult/impossible to change after the server is deployed.
# Change default SSH port for the cloud roles only
# It doesn't apply if you deploy to your existing Ubuntu Server

# Deploy StrongSwan to enable IPsec support

# Deploy WireGuard
# WireGuard will listen on 51820/UDP. You might need to change to another port
# if your network blocks this one. Be aware that 53/UDP (DNS) is blocked on some
# mobile data networks.

# 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.

# Available for the following cloud providers:
# - DigitalOcean
alternative_ingress_ip: false
# Reduce the MTU of the VPN tunnel
# Some cloud and internet providers use a smaller MTU (Maximum Transmission
# Unit) than the normal value of 1500 and if you don't reduce the MTU of your
# VPN tunnel some network connections will hang. Algo will attempt to set this
# automatically based on your server, but if connections hang you might need to
# adjust this yourself.

# Algo will use the following lists to block ads. You can add new block lists
# after deployment by modifying the line starting "BLOCKLIST_URLS=" at:
