Filtering RFC1918 Addresses
Mikrotik RouterOS
- Define an RFC1918 address list
/ip firewall address-list add address=10.0.0.0/8 list=RFC1918 add address=172.16.0.0/12 list=RFC1918 add address=192.168.0.0/16 list=RFC1918
- Perform NAT on traffic coming into AMPR from RFC1918 space
/ip firewall nat add action=masquerade chain=srcnat src-address-list=RFC1918
