[SOLVED] Windows IIS Webserver with Pfsense = Potential Rebind Attack

[Peppe]

Sorry if I post this in the wrong section.

I have a Pfsense 2.3.3-RELESE-P1
Virtual IP Adress setup with IP Alias
NAT 1:1 mapping
Dns Forwarder enabled
A test webb server with two subdomains test1.example.org and test2.example.org

Which results in Potential Rebind Attack if I try to access any of the sites

I have tried both suggestions in this faq; https://doc.pfsense.org/index.php/Why_can%27t_I_access_forwarded_ports_on_my_WAN_IP_from_my_LAN/OPTx_networks

If I enabled NAT reflektion, the sites become inaccessible

If I map split dns - the end result is the same - Potential Rebind Attack

What am I doing wrong?
Thanks in advance!
Regards

EDITED;

I have another network on the Pfsense box which I used to test the webserver and my firewall rules is most likly the problem since it seems to resolv internal rather then go externaly. I have replaced this network with another router and now it works.
So stupid of me but "learning by doing".

Regards
