i have a CGNAT (100.64.0.1/10) address assigned to a routed interface and it won’t ping from another subnet if I assigned a RFC1918 address to the same interface it will there are no other filter rules or NAT rules assigned do Mikoritk auto filter these address and prevent routing

without config, I’m just guessing here check your local address see to it that they are unique for each pool e.g

Local Address 100.64.0.0 IP Pool 100.64.0.1-100.64.0.254
Local Address 100.64.1.0 IP Pool 100.64.1.1-100.64.1.254

i haven’t subnetted these down just using the /10 to encompass them all in the same subnet
