+ | A router performs | ||
+ | - A gateway between different network areas | ||
+ | - Restrict network traffic | ||
+ | - Forward Network traffic | ||
+ | - Track network traffic, allows traffic incoming only if response to out going (one way traffic) This is primary firewall action and primary security action! This is often confused | ||
+ | - NAT (Network Address Translation) is basically mandatory for IPv4 due to limited address space and optional for IPv6 | ||
+ | - NAT obfuscates Local IP addresses behind public addressable WAN IP address(es). | ||
+ | - NAT obfuscation wrecks simple end to end IP addressing that is required for some services, e.g. VoIP. This requires additional services to compensate, e.g. STUN/TURN services. | ||
+ | - I have tried to use IPv6 via a HE tunnel arrangement, | ||
+ | Key networks services, such as DNS and DHCP are separate functions that a router may perform, although correct router setup is required to allow these services to function. | ||

+ | ======Manual Network Setup====== | ||
+ | A lot of network equipment, such as routers and managed switches come with a default access IP address. In most cases this address does not align with the existing address space. | ||
+ | |||
+ | There are many ways to manually change the computer IP to facilitate this, and this depends upon the operating system and software used by that computer. | ||
+ | * '' | ||
+ | * '' | ||
+ | |||
+ | Once the computer network has been manually assigned and network reset check that the network address and mask have been correctly set. If the assigned network mask is incorrect, that is in most cases not /24 (255.255.255.0), | ||
