# Create Access rules to allow the type of traffic that is handled by the Server Pool

Before you can enable Server Pool load balancing using NAT rules, you must create Access rules to allow the type of traffic that is handled by the Server Pool.

## Steps

1. Open the Firewall Policy for editing and add an IPv4 or IPv6 Access rule.
   Note: If the Server Pool uses both IPv4 and IPv6 addresses, you must create separate IPv4 and IPv6 Access rules.
2. Configure the Source, Destination, and Service of the rule to allow the type of traffic that is handled by the Server Pool.
   If you want to restrict the destinations to which this type of traffic is allowed, we recommend creating Host elements that represent the external IP addresses of the Server Pool and using them in the Destination cell of the Access rule.
   Note: Do not add the Server Pool element to the Destination cell of this rule. If the Destination cell of an Access rule contains a Server Pool element, the Access rule applies Server Pool load balancing, and the NAT rules are ignored.
3. Save and Install the Firewall Policy to transfer the changes.
