問題文
A branch turned on load balancing across its two WAN uplinks. Since then an internal server that is published to the internet through a 1:1 NAT rule is reachable only about half of the time, although the rule itself was never touched. What restores the mapping while load balancing stays on?
選択肢
- A change of which uplink is set as the WAN 1 uplink, so that the interface named in the NAT rule carries the traffic.
- A static route on the appliance for the public IP of the server, so that the replies leave through the uplink that owns that address.
- An internet traffic flow preference that pins the local IP range of the internal device to the uplink whose public IP the 1:1 NAT rule uses, added once per rule.
- A VPN traffic flow preference that ties the local IP range of the server to one uplink, because a 1:1 NAT rule is read after the VPN table.
