Troubleshooting NAT Reflection¶
If an improperly specified NAT Port Forward exists it can cause problems when NAT Reflection is enabled.
The most common way this issue arises is when there is a local web server, and port 80 on the WAN is forwarded there. When NAT Reflection is enabled, any connection made to an external web site comes up as the internal web site instead.
To fix this, edit the NAT Port Forward for the offending port, and change External Address to *Interface Address* instead of any.
If an external address of “any” is absolutely required, then NAT Reflection will not be possible on this firewall and Split DNS must be used instead.
