Expressway Clustering with Single NIC for B2B and Webrtc Calls

[sandip.khandekar]

Dear Team,

We have expressway E with single NIC deployement for B2B calls and webrtc calls

expressway E1 at DC LAN1 ( 192.X.X.X -DMZ IP) Nated with public IP

expressway E2 at DR LAN 1( 192.168.X>X-DMZ IP) Nated with public IP

I have one question:

Does expressway clustering is supported for expressway Single NIC deployment model?

We have only one firewall.

Please help me to expressway cluster deployment.

expressway setup details:

DC
expresssway c1 expressway-e1-LAN1

172.28.1.X 192.168.X.10

DR
expressway c2 expressway E2-LAN2

10.130.120.X 192.168.X.15
