|Why did you ISP tell you to put the router in bridge mode? It is not something you would normally do without a good reason, usually when you are trying to connect two routers together.|
The IP address you have is your public IP address provided by your ISP, No. 19,Laser Building,Adadi Alley,South of Saie Park, VAli-e-Asr Ave,Tehran, Iran. It is not you routers address as bridge mode effectively passed everything straight through the router and you have a direct connection to the Internet.
There is no gateway address because in bridge mode you dont need one.
