I want to setup an additional wan address to hit a second web server on
my local network

 

Public network

Wan settings 207.191.115.50 / 24 gw 207.191.115.49 (I know the subnet is
wrong but I don't think that would cause my problem)

Additional IP I want to NAT 207.191.115.52

 

This is the rule I created

Server NAT 

WAN 

TCP 

80 (HTTP) 

10.10.10.11 
(ext.: 207.191.115.52) 

80 (HTTP) 

 

When I request 207.191.115.50 remotely, everything works fine, 

207.191.115.52 remotely gives me no response. 

10.10.10.11 on the local network works fine.

 

Is there anything I am overlooking?
