Question #: 51
Topic #: 8

Your ISP gives you an IP address of 203.0.113.0/27 and informs you that your default gateway is 203.0.113.1. You configure destination NAT to your internal server, but the requests sent to the webserver at 203.0.113.5 are not arriving at the server.

In this scenario, which two configuration features need to be added? (Choose two.)

Afirewall filter

Bsecurity policy

Cproxy-ARP

DUTM policy

Show Suggested Answer

Suggested Answer: A, C

Junos-host and null are two non-configurable zones that exist by default on an SRX Series device. Junos-host is the default zone for all internal interfaces and services, such as management and other loopback interfaces. The null zone is used to accept all traffic that is not explicitly accepted by other security policies, and is the default zone for all unclassified traffic. Both zones cannot be modified or deleted.

Hmm, this seems like a classic networking issue. I'm guessing we need to enable proxy-ARP to handle the NAT configuration properly. And maybe a firewall filter to ensure the traffic is being routed correctly.
