service on a H3C S7506 switch to access the Internet;
z The private IP addresses of the two PCs in internal VLAN 2 are 192.168.1.2 and
192.168.1.3 respectively;
z In the S7506 switch, the LPU implementing NAT is in slot 3;
z There are three valid public IP addresses in the NAT address pool: 200.18.2.3 to
200.18.2.5;
z The interface IP address of VLAN 10 is 200.18.2.2, the subnet mask is
255.255.255.252;
