i did not change any firewall setting, the default should be not blocking any ports right ? or i should explicitly allow those ports ? i tried, but still not able to access those ports.

I saw some post online about the firewall router, do you think for maxis router we need to do something like this ?

double port forward ?

but what is firewall router, how can we access to it ?

May i know what do you mean by disabling the firewall for all 3 profile ? Actually i tried to use the DMZ to allow access to my internal ip which link to my server, but seems like it is only accessible when you are connected to the network, when we try to connect from outside, it failed.
