One of the server host uses the same internet ip to get on to internet and also receive the request from internet to itself. this was done for address space restraint. But a recent security audit has forced to seperate the communication for this server using a single internet registered ip both ways.
i.e server host 10.19.2.2 will use internet IP X.X.X.X for internet bound data from itself & the same X.X.X.X internet IP will be used to reach this host when any other host on internet needs to start a new connection to 10.19.2.2.
Insights into how best,this can be achieved, will be helpful.
Taking the eg. that you have stated, our policy needs me to use the same public IP for this server host 184.108.40.206 when going out to internet & use the same public IP for inbound connections to this server initiated by any source from the internet.
