How to access WAN IP from LAN network?

HI,

if you run a tracert using DNS from a PC where does it end up at?

Ian

Did you mean tracert example.com? if yes, the tracert result show me 2 hop, 

the LAN gateway and the WAN IP 

So does your firewall rule allow http/https access to the WAN, this assumes the application uses http/https?

Ian

I allow Any services to the WAN. 

The issue is from may local network cannot browse to example.com but outside is OK.

It is OK now,

Due to misconfiguration. Missing Routing Rewrite source address and set it to MASQ. 

Always keep in Mind, a DNAT could be dangerous from security perspective (RDP issues etc.).
