Firewall between DC and DR

Hi,

I need suggestion, we have Data Center and Disaster Recovery connected with point to point link. link is connection our DC sever segment with DR server segment. It is mainly for replication of data. in future VM, vlan extension is possible. 

 

Now client is asking us to install firewall. at both end of point to point link. Here I want to tell you that server segment at each end is fully separated with firewall. 

 

My concern is Why we need firewall between server segment between DR and DC connected with P2P link. Can we go for firewall. What will be the impact of having firewall between DC and DR server segment on replication and other services between DC and DR.

 

I have not seen firewall between DC and DR server segment in my previous projects.

Hi,
So you have a dedicated P2P connection in between DC&DR , then my suggestion is not necessary a Firewall in between that. As per your post your serverfarm is already protected by firewalls.
But some organisations like banks and all have more security constraints and they design to add a firewall.

Typically you would have one fw per dc. Links are most times layer 2 with stretched vlans. So each dc had an internet break out and fw in ha deployed.
