First of all, you have to determine whether your route opens the external network access route management page, which also uses 80 ports;
Secondly, if 80 ports are prohibited by telecommunications, such a setting cannot be successful.
If it is a fixed IP, you don't need to use domain name resolution such as peanut shells.
When changing ports, remember that the ports on IIS, firewall and router should be consistent.
It is a trouble point when IE enters the address, such as ht Harmony tp (this browser that must add IE kernel): //XXX. XXX.X.XX:8080, that's all.
