Your company has a Web server in the trust zone. You configure a NAT rule to allow Internet users from the untrust zone to access this Web server. Internet users use the public IP address 70.1.1.1 to access this Web server, but they report that the server is not accessible.
Referring to the exhibit, which configuration change would resolve this problem?
