How to configure to allow access to senhasegura through the Google Cloud Platform balancer

1. First, the subinterface must be created using the command below:

vim /etc/network/interfaces.d/eth0:1

2. After creating the subinterface, it will be necessary to create its properties, for that use the following command:

auto eth0:1
iface eth0:1 inet static
    address <VIP_IP_ADDRESS>
    netmask 255.255.255.255
    pre-up arptables -t filter -F INPUT
    pre-up arptables -t filter -F OUTPUT
    pre-up arptables -t filter -A INPUT -d <VIP_IP_ADDRESS> -j DROP
    post-up arptables -t filter -A OUTPUT -s <VIP_IP_ADDRESS> -j mangle --mangle-ip-s <IP_DA_ETH0_DO_SERVIDOR>

In <VIP_IP_ADDRESS> insert the Google Cloud Platform Balancer IP parameters, and in <IP_DA_ETH0_DO_SERVITOR> insert senhasegura IP, as shown in the image below.
