How do I subnet 131 subnets and 300 workstations?

Currently we have 30 workstations within our company. We use a Class C address with 192.168.x.x / 24 thus giving us 65,534 subnets with 256 hosts in each. Now I don't think it was setup correctly for future growth. We are moving to bring 130 branch offices with 260 + pc's into our LAN thus creating a WAN environment. 260 + because some offices have 3 or 4 pc's.

1) Do I need to change to a Class B, 22 or 23 bit network or is there something else I can do to make my situation work?

2) How do I keep the branch offices from browsing our network?

3) Each branch office will have a Symantec 320 firewall. I assume that I can use the secure tunnel of the branch office that I want to connect to to use Remote Desktop Connection to troubleshoot user issues etc. Is this correct?

We are implementing a gateway-to-gateway solution using IPSec tunnels. I have never done something of this magnitude. Please offer tips, suggestions, and pitfalls to avoid.

I think that you have about 256 subnets with 256 IP in each one
it's about a 65,534 IP's

the simpple and clear wya is to put every branch in different subnet
i mean First Branc - 256 IP's
Second Brach also 256 IP's
and you can make VPN bettween branches that you want

if you have any special quetions ask
