I have two networks 1&2. Both have separate internet connections .
ASA1 in network1 has three interfaces (inside/192.168.1.0/24) dmz (172.16.1./24) and outside (56.*.*.*/28). Its DMZ has connectivity to a layer 3 switch of second network network2. Network2 has some servers with public IP 210.*.*.23 .with dns name mywebsite.com and corresponding private IP 10.10.128.121
Right now when a host in 192.168.1.0/24 requests mywebsite.com or 210.*.*.23 server , the traffic routes through the internet causing the wastage of internet bandwidth .
Could anyone please help me to direct this traffic (i e all traffic from 192.168.1.0/24 to mywebsite.com or 210.*.*.23) through the DMZ of the ASA to the layer 3 switch
This layer3 switch in network2 is behind the ASA2 so the traffic to 210.*.*.23 has to be natted to 10.10.128.121 also.
is simple, do a NAT exclude on both firewalls so that traffic between the 192.168.1.0/24 and 10.10.128.0/24 doesn't get NATed and all traffic and both networks will be able to connect using their private IP addresses.
