GNS3 Notes

Some notes about GNS3 on Windows 10

1. Till GNS3 version 2.2.29, the WinPcap is required for both uBridge and Dynamips. Hosts inside GNS3 may not connect to host PC (ping replied destination unreachable) if WinPcap is not installed. uBridge is compiled with WinPcap SDK, so it cannot be replaced by the WinPcap compatible-API provided by NPcap. 
2. Serial console is required for a appliance in GNS3, such that its console can be redirected to a TCP port which can be connect by telnet programs on host PC.
3. The VPCS in GNS3 is initiated with the same MAC address (stating at 00:50:79:66:68:00 by default). If there are two VPCSs running on two different GNS3s which are connected in a physical LAN, this will raise the MAC address conflict problem.
