I have a requirement to setup a network so that an internal server communicates with outside world through different WAN networks. I have three separate WAN connections terminated on a single Cisco 6500. The internal network also connects to the same switch.
External VLANs: Ingress, Egress and Management
Internal VLAN: Internal
1. Management traffic can only talk to the internal server(s) via Management WAN;
2. Application traffic can only talk to the internal server(s) via Ingress WAN;
3. Outbound traffic originated from internal servers has to go through Egress WAN;
4. Internal servers use private IP addresses
For example, I have:
Servers on Internal VLAN:
The mangement traffic (i.e. SNMP, ssh) uses the following public IPs to reach each server:
The application traffic (i.e. www, ftp) uses the following public IPs to reach each server:
The traffic initiated from the servers uses the following public IPs to access the Internet:
Given the requirements above, how do I design/configure my switch to achieve the goal? I've done some searches on the forum with no luck. Please kindly advise. Any hint would be appreciated too!
