Mikrotik

Good day. There are
three networks 192.168.1.0, 192.168.2.0, 192.168.3.0 Proxy
server 192.168.1.1 and Internet access 1.1.1.1 to address 1.1.1.1 Thank you.

Answer 1

You can wrap all the necessary packages to the desired address, and there is already a nat or proxy - to your taste.
Well, for example, without special details:
/ip firewall mangle
add chain=prerouting dst-address-list=Local src-address-list=Local
add action=mark-routing chain=prerouting disabled=yes dst-port=20,21,80,443, 8080 new-routing-mark=To_proxy passthrough=no protocol=tcp src-address=10.1.1.0/24
/ip route
add distance=1 gateway=10.1.1.254 routing-mark=To_proxy scope=40 target-scope=30 Wanted by
client or not, it transparently transfers it to a server that already knows who to let through, who to cut banners, and who to facebook, but especially malicious cut js with pictures)))
