I have a peculiar strategical workout for you brains!
It goes something like this..................
One of my client has two offices in different cities, their server is hosted in a data centre.
They have a leased line connection between the DC to the office on both locations, as such as it provides them two /30 subnets (Thus, forming a point-to-point link between the office & DC).
Office A has an ASA 5505 (Security + licence), Office B has an ASA 5510 (Base licence) and DC has a Cisco 2821Router (ISR).
Our ISP also provides a batch of public IP /29 addresses on both office locations.
office A LAN- 192.168.1.0 /24
office B LAN- 192.168.2.0 /24
DC LAN- 192.168.3.0 /24
Traffic from site A+B must go through the DC in order to see the outside world (Internet) and vice versa. What, I've done so far was to PAT the traffic from LAN A and LAN B to the DC (so both sites can access the server, which they did). However, it seemed to be extremely slow while browsing on the server and whilst, PC's in site A&B can ping the server (in DC), I was unable to ping any hosts on LAN A&B, probably because of PAT setup.
I know my approach was poor, hence I come before the experts. Please suggest a better approach to me in this current topology.
If you guys need a topology map, let me know.
