Configure IP settings

Configure DNS

DNS is an Internet service that translates domain names into IP addresses. On the Internet, whenever you use a domain name a DNS service needs to translate the name into the corresponding IP address. For example, the domain name www.wikipedia.org might translate to 208.80.152.2.

If you want to obtain DNS server addresses from a DHCP server, tick the Obtain DNS server address automatically check box. If you want to manually configure DNS server addresses, untick the Obtain DNS server address automatically check box and in Preferred DNS server and Alternate DNS server type the preferred DNS server and alternate DNS server IP addresses as IPv4 addresses, example 1.2.3.4. To modify the resolution behavior for unqualified DNS names enter search domains as space separated list. In case you leave everything empty (Obtain DNS server address automatically check box unchecked, no preferred and alternate DNS and no search domains) the DNS settings for your physical network interface are used (/etc/resolv.conf will not be changed). This is useful for users who are managing their /etc/resolv.conf by some other means, like with dnsmasq for example.

Configure routes

In general terms, routing is the process of forwarding packets between connected networks. For TCP/IP-based networks, routing is part of Internet Protocol (IP) and is used in combination with other network protocol services to provide forwarding capabilities between hosts that are located on separate network segments within a larger TCP/IP-based network.

Based on the Use default gateway on remote network setting, one of the following occurs when the VPN connection is active:

When the Use default gateway on remote network check box is cleared, Internet locations are reachable and intranet locations are not reachable, except for those matching the network ID of the Internet address class of the assigned IP address. When the Use default gateway on remote network check box is selected (the default setting), all intranet locations are reachable and Internet locations are not reachable, except for the address of the VPN server and locations available through other routes. If you want to setup your VPN connection for Split tunnelling tick the Use following explicit routes to intranet locations radio button and add routes accordingly.
