I have one PC they have one NIC and two USB port I want internet through USB and Local LAN through NIC But problem is this the IP of Local LAN is Class A and Internet provider IP is Class C.
I configure but both connection is not work at asame time.
Pls provide the solution…
Just try this
Connect USB NIC on USB port. Now you have an extra nic:
Assign DHCP to USB NIC.
Directly connect USB NIC to Modem of Internet Service Provider
Assign Local Lan fixed ip adress to local NIC (something like 192.168.100.10). Subnetmask 255.255.255.0. If you want internet via this local lan, gateway is ip adress of the internet modem, dns is dns of internet service provider.
