Kilight Cao 165.1 246 LPS8-V2 supports flexible network set up for different environment. This section describes the typical network topology can be set in LPS8-V2. The typical network set up includes:
Xiaoye 26.1 247
Kilight Cao 165.1 248 * **WAN Port Internet Mode**

253
254 === 2.2.2  Use WAN port to access Internet ===
255
256
257 By default, the LPS8-V2 is set to use the WAN port to connect to an upstream network. When you connect the LPS8-V2's WAN port to an upstream router, LPS8-V2 will get an IP address from the router and have Internet access via the upstream router. The network status can be checked in the (% style="color:blue" %)**home page**(%%):

Xiaoye 112.1 798 This is caused by the inconsistency between the built-in TTN-Stack domain configuration and your login URL.
799
800 By default, ttn-stack uses the gateway's domain name for URL resolution, but in some networks, they prefer to resolve IP-v4 addresses.
801
802
803 So you can change the domain name of the TTN-Stack configuration to the IPv4 address.
804
805 **Click the update URL button to configure the URL with the current eth port address.**

Kilight Cao 225.1 818 == 9.3  Fallback IP does not work, how can users check ==
Kilight Cao 192.1 819
820
Kilight Cao 172.1 821 When the computer has completed the above fallback IP configuration,the LPS8v2 Web UI is still not accessible via fallback IP.
822
823
824 **1.Check whether the configuration is correct**
825
826 Run the CMD command to ipconfig and ping 172.31.255.254.
827
828 If this fails, the user needs to reconfigure.

833
834
835 **2. Check whether the firewall is disabled**
836
837 If the firewall is not down, this will affect access to the gateway.
