# Accessing LSA over Network Address Translation

Network Address Translation (NAT) enables private IP networks that use unregistered IP addresses to connect to the Internet. NAT operates on a router, usually connecting two networks together, and translates the private addresses in the internal network into legal addresses.

To access the LSI Storage Authority application over a NAT environment, the LSA server must know some information about the NAT server settings.

Perform the following steps to configure the parameters in the lsa.conf file in the conf directory.

1. Open the lsa.conf file in the LSIStorageAuthority/conf directory.
2. Specify the public IP of `nat_ipv4_ipv6`.

   For example, if the public NAT IP address configured is as `135.24.227.198`, you must specify nat_ipv4_ipv6 = 135.24.227.198.

3. Restart the nginx service and the LSA Service for the changes to take effect.

   If you have multiple public NATs (for example, `135.24.227.198`, `135.24.227.199`, `fe80::dc8d:e156:41e1:b06`), you must specify them as nat_ipv4_ipv6 = 135.24.227.198, 135.24.227.199, fe80::dc8d:e156:41e1:b06
