質問 126
A BIG-IP device is configured with both an internal external and two Corporate VLANs. The virtual server has SNAT enabled and is set to listen on all VLANs Auto Last Hop is disabled. The Corporate users are on
10.0.0.0./24 and 172.16.0.0/12. The BIG-IP has a Self-IP on the 1.0.0.0.0./24 subnet.
Internet users are able to access the virtual server. Only some of the Corporate users are able to connect to the virtual server A BIG-IP Administrator performs a tcpdump on the BIG-IP and verifies that traffic is arriving from users in 10.0.0.0/24.
