Networking question
What woud be the best way to implement a WAN for the following scenario.
Three locations are involved.
Location A: Internet connectivity with T1 connection.
I guess i need to have a router and for security purpose i have chosed Cisco PIX firewall for security protection. I have about 35-40 Computer network running on CAT 5 cable with HP pro curve 4000m ethernet switch. i do also have bunch of static IP addresses. Chosen Cisco 2600 series router.
Location B: DSL Internet Connection. 5 static IP address
very small network, basically 3-5 computers.
Location C: ISDN internet connection. 3 static IP addresses.
3-5 computers network.
the objective is to setup a WAN between all the locations so that when ever any user at any location browses the network neighborhood , he/she should be able to see all the computers at all the locations altogether. I need to have a firewall at location B and C so that the connection between all threee locations is safe and secure. (of course the firewalls wud be configured accordingly). what kind of router/firewall would be the best to have reliable and stable WAN among all 3 locations.
Please suggest and advise.
thanx,

thanx for the comments.
what would you recommend on the TCP/IP adressing scheme. if i want to implement it as follows.
Location A:
Private IP Addresses, 192.168.1.1-192.168.1.254
Subnet mask: 255.255.255.0
Location B: 192.168.1.1-192.168.1.254
Subnet mask: 255.255.255.0
Location C:
192.168.1.1-192.168.1.254
Subnet mask: 255.255.255.0

any further information u think is necessary for the implementation part in terms of configuration, any recommendations.
appreciate your response.
appreciate your response.
Suggestion: do NOT use the same network at each location.
I don't even like to start at 1 because any reconnaissance ping sweeps will be cought before they get to you if you use higher numbers:
Location A: 192.168.122.0
Location B: 192.168.123.0
Location C: 192.168.124.0
etc..
all subnet mask 255.255.255.0

I agree with lrmoore
Use different ip ranges and also use higher numbers
