Hi,

you can do a site-to-site IPSec VPN but you'll need a remote router for the other site.

As i understood you want to make these 20 PCs able to reach the office which you have a Cisco router there. but the subject made me confused (How to connect Single cisco router to split the network).

Anyway, if you need to connect both sites together and you only have one router at the office, you can either use your ISP to buy a VPN connection between both site & office (which will cost alot). or you can just buy one puplic IP address and use it in your cisco router, so that all PCs can establish PPTP connections with that router which will allow you to connect both site & office together. if that what do you need, please tell me in order to support you with needed configurations. unless, kindly clarify.

I highly appreciate your support. I do have static IP from the ISP so please help me to configure that. So that site people can connect our office through VPN.

My cisco router is 1800-1840

Pls note: my network is like this

ISP->Fortigate firewal-->Core Switch

Please follow this link:

but kindly change the security settings to be as that image (in order to pick just ms-chap & ms-chap-v2)

==================================

You can also make a NAT in order to let these PCs to reach internet from that static IP in the office. If you are interested, please let me know in order to support you with the needed configuration "God Will".

Waiting your feedback.
