I'm aiming to build the following network (might need to open image in new tab due to width):
- Assume those BGP links are different ISPs
- Same ASN is advertised to both ISPs
- Sites are interconnected via private line
- BGP default routes only
- We have a /24 (public address space)
- EDIT: I should add that we're already advertising this /24 with BGP at siteA. So I'm essentially looking to add SiteB
- Server 1 is accessible on the internet via NAT
My Question: I'm hoping to expose Server 1 via the same public IP regardless of which ISP a client comes in through. So therefore, I'm assuming the accepted method is to have the same NAT rules on both routers? Is this possible? What are the downsides to this?
