I have 2 adls links with 192.168.1.1 internal ip boths. ADSL1 allow internet web access to all internet domains, and ADSL2 allow web access only to domains of my country. At this moment, i have a Debian 11 server as non-transparent proxy-firewall to 192.168.0.1/24 network with one nic card connected to ADSL1, and i need connect the second ADSL and use it only for web request to my country domains accross the proxy service installed.
Note: it´s not possible for me change the internal´s ip address of adsl modems
