Hi,
When we open port 8088 or 443 to get remote access perspective web pages we also make possible remote access to the designer and gateway config pages. So if some one can get password he can easily go to config page and change all security setting.
I believe if we have separate port for desinger and gateway from perspective port it is much safer for remote access applications.
We can drop any access to that port with firewall and even user and password are compremised at least with using security zone(that limit all outside IP) the hacker can’t send any command.
