I am trying to use twice nat along with dns_alg to support a framework, and take its measurements.
I have a private network 192.168.0.0/24
this network contains www,dns,dhcp etc for its own use.DNS,WWW are also used for global access. I have say eg. 6 public addresses that have been allocated to me.
192.168.0.0/24 | ----router/NAT ||=--- 6ips-----isp-----bigger isp-----whatever.
I want to : -Allocate all those ip onto single router's outside nic , or alias them, but i have only 1 nic.
-Use natting, so that whenever the internal dns replies, the router should modify it to match a global address(runtime selection not static). Whenever the outside dns replies , the nat should again map the public address to one private address say 192.168.0.32, and then it should reach the client.
- use source and dest natting, so that, the internal addresses never appear to communicate with the outside world, rather they seem to only communicate with their lan.
how should i proceed +
