SonicWALL TZ400 Access Single X0 Interface IP from Many X3 Interface IP’s
Posted on 2016-11-09
I want to be able to access X0 (LAN) IP 192.168.1.51 from X3 (LAN2) 172.16.1.0/24
1. X0 (LAN) and X3 (LAN2) are trusted interfaces and have corresponding Any/Any access to each other as separate firewall rules (automatically created by SonicWALL when trusted is enabled).
2. I created address object AO_X0_IP for 192.168.1.51 and a corresponding address object AO_X3_IP to translate to 172.16.1.51
3. I then created address object AO_X3_RNG for 172.16.1.0/24 for full range of subnet
4. I then created and enabled the following NAT policy
a. Original Source: AO_X3_RNG
b. Translated Source: Original
c. Original Destination: AO_X3_IP
d. Translated Destination: AO_X0_IP
e. Original Service: Any
f. Translated Service: Original
g. Inbound Interface: Any
h. Outbound Interface: Any
This all seems correct, but yet I cannot access, or even ping, X0 (LAN) IP 192.168.1.51 from X3 (LAN2) 172.16.1.0/24. That is, when I'm on the X3 subnet and I ping 172.16.1.51 it should translate to 192.168.1.51 on X0 and reply back, but no joy. Can anyone help me solve this problem? Thank you.
