i have a small office network in my shop which consists of
A PC server (A)
A PC client (B)
..
A and B are connected through a cisco switch and the CISCO switch is connected to a 3g Router for internet connection for the network.. (a static IP has also been assigned to the 3g router making in accessible any time.)
now what i want is..
I have another Laptop at home. (C)
Laptop (C) have internet connection as well.
I have a custom built software installed on all three machines.. 2 are always connected to the network.. i.e. A and B
but C is only connected when im at shop..
i want C to connect over the internet when im not at the shop.. but at home or somewhere else with internet connection.. i want this custom built software to work everywhere..
this means.. i shud somehow use that static ip.. put it sumwhere in the internet configuration of my laptop.so when im at home. i just open up that software and it knows that it have to connect to '111.111.111.111' .. .etc etc..
but at the same time i should be able to use my home internet for browsing..
this means..
im using internet at home for surfing internet
and
im using home internet to connect to shop internet and network. and have all data live pulled out of PC Server to this laptop..
PLEASE GUIDE. URGENTLY REQUIRED.!
