One of my client is having two LANs / Intranet on seperate places in one city itself. Now They have two live IP from both side. Now suppose LAN 1 have PC A B C and LAN 2 have D E F. Here if A wants to see or share files with D E F of LAN 2. But how it can be done ? Because LAN 1 and 2 are connected through internet only by live IP. While ABCDEF are having DEAD IP for LAN.

Any suggestion with 3rd party utilities and without 3rd party utilities ?

parth , simple . Get ADSL or LL , and ask for STATIC IP from your ISP . Buy the necessary routers that support VPN and form a Virtual Private Network over the internet . Want more details?

I have managed permission from MD of company to get STATIC IP also they now understands after my explainations about router and switches....

Thank you for your time....

Yeap you are right though problem is they want buy router or switches for VPN or VLAN. And more ISP will charge for STATIC IP. Client is very rigid to invest in for their good facility. Therefore I have to find other solution if you have. Waiting for more from you....

Thank you....

VPN Endpoint routers. You create a tunnel between the 2 routers. Dynamic IP's only pose a problem then the address changes. Some ISP's don't change them often. Some do. Without a static IP, when the IP address changes you lose connectivity and have to re-establish the tunnels using the new IPs. Just a lot of admin work. But if you don't mind putting up with having to monitor the tunnels all the time then just use VPN Endpoint routers.

Definitely will turn on to End point routers in near future.

Thank you... for your time....

I would recommend either SonicWALL or Cisco PIX gear. The hardware is built for these jobs. They license by number of users on the LAN side for each box.

I've done this configuration dozens of times for clients, and have swapped out lots of buggy software configurations for one of these two products.

You will need a static IP at ONE of these sites (usually the head office), the others can be dynamic if you want to save on costs (and the other VPN devices just connect to the static one reguardless of their IP). For troubleshooting and setup it is easier if they are all static however.

Just as a note - all networks will need to be on different IP subnets for this to work properly.

You would definately need to get a static IP from your ISP. If you dont want to invest in Routers or have problems with VPN, you could simply do FTP.
