I'm having trouble defining the possibility of a multi-WAN network proposed by an IT solution company since I'm no CISCO Geek.
Our company has offices all over the world (US, India, China), all connected in a "World WAN" so we can access certain resources in other countries. IP: 10.x.x.x for each country
In US (IP: 10.149.x.x), the company has several offices (NY, LA, San Francisco, New Jersey), only New York (10.148.5.x) is connected to the World WAN now. We were proposed a solution of connecting all US offices into a smaller network called "American WAN" so we can share resources between offices in US and also be able to access World WAN from anywhere. What I wonder is
- Is this network possible ?
- Can one firewall be able to handle both WANs, is it easy configure this ?
- Is it possible for all US offices to access resources from World WAN, can this be defined by ASA firewall configuration ?
- What should play the role of DHCP here ?
Any advice will be very much appreciated.
