When a user connects to a VPN and experiences connectivity issues to an external server, the problem is often related to routing or network path issues.
E. tracert:
Traces the path packets take from the user's device to the destination server.
Helps determine if the traffic is being blocked or misrouted.
F. route print:
Displays the device's routing table.
Helps diagnose whether traffic is being sent to the VPN tunnel instead of the correct external server.
Incorrect Options:
A. nslookup: Used for resolving domain names to IPs (DNS troubleshooting), but this issue is likely routing-related.
B. tcpdump: Captures packets for deep packet analysis, not typically the first step in diagnosing a VPN-related access issue.
C. arp: Used for resolving local network MAC addresses, not relevant for external VPN issues.
D. dig: Like nslookup, used for DNS queries, but not useful for routing problems.
