I have 8 static IP from ISP and I suppose can use 6 IP in range: e.g. x.x.x.205-x.x.x.110 and I want to config it, so all traffic from my Email server(192.168.0.2) can be routed via specific IP, e.g. x.x.x.206. And all traffic of office workstation to be routed with x.x.x.205
How can I configure it?
currently, I use below for incoming traffic. ip nat inside source static tcp 192.168.0.2 25 x.x.x.206 25 extendable
