| ==Introduction==
| |
|
| |
|
| ==Configuration overview and prerequisites==
| |
|
| |
| Before we begin, let's take a look at the configuration that we are attempting to achieve and the prerequisites that make it possible.
| |
|
| |
| '''Prerequisites''':
| |
| * Two RUT/RUTX series routers with RUTOS firmware;
| |
| * An end device (PC, Laptop) for configuration;
| |
|
| |
| If you're having trouble finding any page or some of the parameters described here on your device's WebUI, you should turn on '''"Advanced WebUI"''' mode. You can do that by '''clicking''' the '''"Basic"''' button '''under''' '''"Mode,"''' which is located at the top-right corner of the WebUI.
| |
| [[File:Networking rut9 manual webui basic advanced mode.gif|border|center|class=tlt-border|1102x52px]]
| |
|
| |
| ==Topology==
| |
|
| |
| RUT1 - RUTX11 as a hub. It will be our "default gateway" for spoke device. RUTX11 has a LAN subnet of 192.168.11.0/24 configured on it, which should be reachable by the spoke.
| |
|
| |
| RUT2 - RUT955 as a spoke. It will be connecting to a hub for basic internet access. RUT955 has a lan subnet of 192.168.9.0/24 configured on it, which should be reachable by the hub.
| |
|
| |
| ==RUT1 (Hub) configuration==
| |
| Start by configuring HUB (RUT1) device. Login to the WebUI, navigate to '''Services → VPN → IPsec''' and add a new IPsec instance. Configure everything as follows.
| |
|
| |
| '''Note:''' '''''Not specified fields can be left as-is or changed according to your needs.'''''
