I am responsible for managing IT in 4 offices and all of them are using internet seperately. All these 4 offices are not connected each other. They all have their own firewall, switch, and WIFI. Among these 4 offices 2 offices has VSAT connection which has static private ip 10.191.50.50 & 10.192.85.132 respectively. ISP has given only static ip (not public ip). Two offices has Wireless modem connection which has linux firewall which also act as a router.

Assume
Office A
VSAT connection
VSAT IP : 10.191.50.49
Gateway : 10.191.50.50
Internet speed: 384 kbps
ISP NAME IS : A1

Office B
VSAT connection
VSAT IP: 10.192.85.132
Gateway : 10.192.85.133
Internet speed is 256/512kbps
ISP NAME IS : B1
Linux Sever as Firewall shares internet connections
Lan IP: 192.168.1.1/255.255.255.0

Office C
Wireless Modem
Linux Server as Router and Firewall shares interet connection
Linux server has open vpn
Static public ip : 41.100.40.12
LAN ip: 172.16.1.1 /255.255.255.0
Internet Speed : 1 MB

Office D
Public IP : 78.22.33.78
Sub net mask : 255.255.255.0
Sonicwall as a firewall with VPN enabled.
Internet speed : 512kbps

How to interconnect all these networks, i am not sure how to connect all these network. I would prefer VPN to connect. In this place there is no MPLS connection available.

Please help how to interconnect these offices in steps.

Thanks in advance

Do any of the other offices have an Astaro? If not, are they capable of creating a site-to-site IPsec connection to the Astaro?

This site, www.astaro.org, is for users of products by Astaro Corporation, Astaro Internet Security - Simplifying Network, Mail & Web Security. The Astaro Security Gateway is their flagship product; it provides basic firewall services and can be upgraded to provide extensive VPN choices, advanced Network Security, Anti-Spam, Anti-virus for surfing and email and more. You can get more precisions from the Astaro website.

The Astaro "Essential Firewall" soffware version is free and includes servers for PPTP and L2TP over IPsec. Although this would not allow you to establish site-to-site VPNs, replacing your current linux firewall software with this Astaro product would allow you to establsh a VPN into each site from your management PC. I don't know if the SonicWall provides that capability.
