I would like your opinion about connecting 3 Cisco PIX 506e firewalls. I have 3 offices which I would like to connect to eachother. This must be done by creating VPN's. The connections between the offcies are made by direct fiber connections (LAN-to-LAN, no routing, no internet access). Is it needed or recommended to use routers between those connections in front of the PIX firewalls. OR it is possible to give the 3 firewalls IP-addresses like 10.10.10.1 .2 and .3, creating internal ranges at the 3 offices and use static routes. Is that possible? What do you recommend for this scenario?
