For this problem maybe I must say what is a network structure on fiscal machine.
The Server is in office in back side of router. The webpage can access because in router i made NAT option for router IP. Everything's with client webpages work correctly, but access to admin panel on mscp can be use only into office.
If I am out of office and I want to go in into admin panel, web browser say that this page is not there.
I'm sorry for bad English.
