is. In addition to the IP address and mask, the packet also has the lease time limit corresponding to this address. Of course, the assigned IP address may be used by other hosts and may cause IP conflict. 3. After receiving the

address, the communication between different network segments will be based on the IP address of the host network to search the path, Therefore, as a LAN gateway router device usually has a ip-mac dynamic corresponding table, which is automatically generated and maintained by the ARP communication protocol. We can ent

1. On the vro logon page, click static ARP binding settings under "ip and mac binding" on the left, as shown in the following figure.2. Now I click "static ARP binding settings" and open it, as shown in the following figure. The mac address in the red box is yours. We can check it in the local connection.3. Click "save"

. The so-called "Lease Term" refers to the effective period of time when the DHCP server of the wireless router is assigned to the IP address used by the common workstation. If the flexibility of the wireless network set up is relatively high, we can try to adjust the lease time to a little shorter. If the wireless network is set up for a fixed user, we can try to adjust the lease time to a little longer, t

The complexity of the network structure also makes it difficult for us to maintain some of its services. Sometimes, some faults may inevitably occur. Here we will mainly explain the problem that the client in the DHCP relay fault cannot obtain the IP address of the same network segment as the IP address through the rel
