[isf-wifidog] Can ExternalInterface and be set to to the same NIC in wifidog.co nf

[tukey]

Hello,

I am using Wifidog gateway on my Linux server.

My Internet NIC (ExternalInterface ) is wlan0, and the internal interface (GatewayInterface) is same.
It seems that the gateway does not work, except for it can only
redirect an url to the portal.
The "FirewallRuleSet global" section in my wifidog.conf does not work either.

So, my question is:
Can ExternalInterface and GatewayInterface be set to the same NIC ?
However, I did that, and it seems that there was no error messages.

I will appreciate any help.
