Dual WAN (ONE ISP and MPLS link)

Sharan.k — Sun, 06 May 2018 07:38:16 GMT

Hello All,

Need your help/guidance on the following requirement

We have 2 WAN links, One ISP with Static public IP and MPLS connection for Internal server access.

Requirement: 1) All the Internal users (Trust Zone) has to go through ISP Wan for Internet access

2) Secondaly, to Access Internal Web application servers Hosted in MPLS cloud(Private Cloud) the traffic has to be routed through MPLS link.

For Option 1: we have configured NAT and security policies and working fine.

to access internal MPLS cloud server we have a private DNS servers.

Please guide us on the DNS config and how to router the traffic to MPLS cloud for Web application using Policy based forwarding.

Thank you in advance.

You shouldn't need any special DNS settings as long as your clients can access a DNS server that can resolve the names of the cloud environment. You say that your private DNS server can resolve those names so you shouldn't need to do anything else.

For the routing, you probably don't need PBF. If there is only a single path to the private cloud, you could use a static route for access.

Static routes and policy's allowing said traffic to its destination (MPLS) is all you need for that traffic
