The Port Forwarding with Public ip is not working internal network
I have a problem with port forwarding after I changed comcast business modem.
I have comcast modem and own router connected to modem.
The comcast modem has public ip 71.59.xxx.xx and private ip 192.xxx.x.x
The router has wan ip address 192.xxx.x.x and private ip 10.x.x.x
All computer are connected to own router. The server computer has static private ip 10.x.x.xx
The network are same as before only different is new modem.
I changed the modem DMZ set to 192.xxx.x.x and changed firewall disabled.
I did not change anything own my router. (the router DMZ is set to 10.0.0.15)
If I put ip address 192.xxx.x.x on web browser, it connect to 10.x.x.xx. The port forwarding looks working but if I put public ip 71.59.xxx.xx then it show me comcast modem login.
I tried from my iphone with public ip then it connect to server 10.x.x.xx if I turn on WIFI on my iphone then it show me the comcast modem login.
I use the public ip address only for my job from internal and external network. the problem is if I turn on iphone WIFI and connect to internal network. the port forwarding is not working with using public ip.
The setting looks OK but why?
