Problem Description

There is a computer on the intranet that cannot access the IAG console, but can ping the IAG bridge address, but cannot telnet the console port. Other computers are normal

Process——

  1. Open the pass-through test on the IAG, but still cannot log in to the IAG

  2. Capture data packets for analysis. The computer telnets the IAG's console port, but the data packets do not reach the IAG.

  3. Capture the data packets of the computer pinging IAG. The computer shows that it is connected, but no data packets can be captured on IAG.

  4. Use the computer tracert to trace the route and find that after one hop, it reaches the IAG bridge address 192.168.199.1

  5. Check the computer network port configuration and find that there is a virtual network port with this address
