Yes, you can. If you have multiple servers at Tilaa, you can create a virtual network through our dashboard: https://my.tilaa.com/virtual_networks/add
You can name the network and select which servers you want to add.
After you have saved the virtual network, restart your servers to add the new network interface. Please note, most Linux distributions do not show unconfigured interfaces unless you use 'ifconfig -a'. In most cases, the new interface will be eth1.
Please note: It's important to restart the server through the Tilaa dashboard for the added changes to have an affect!
You can now configure an IP address from a private range such as 192.168.0.x on the interface.
For CentOS/Fedora/Scientific Linux, create an interface configuration file: /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1 BOOTPROTO=none ONBOOT=yes
For Ubuntu/Debian, modify /etc/network/interfaces and add:
iface eth1 inet static
For FreeBSD, modify /etc/rc.conf and add:
ifconfig_em1="inet 192.168.0.1 netmask 255.255.255.0"
Press Windows Key+R and launch run and type either of below commands and press enter:
A new interface should have appeared after the reboot of your VPS. You can now set the desired IP-addresses. Note: Please leave the default gateway and DNS fields empty!
After doing so on each server, you should be able to ping from one server to another.
To add a new VPS to an existing network, click 'Details' at the server's Network configuration. On the Network Interfaces page, click 'Add interface', select the network you'd like to add and click 'Save'.
