we used public IP 4-5 C-class
and local IP 10.0.0.0/8

but, ..

in firewall I put log traffic and have: ,
proto41, 192.168.1.103>64.202.189.170 , len63 ... this is not IP we have in networks.

what is this ?

we drop this traffic , is this ok ?

now I see traffic , from our IP public (our client ) but to 192.168.100.1 ...

proto UDP ?

we have v3.2 on 2-3 core-gateway routers, but most AProuters are v2.9.50

if all this is ipv6 over ipv4 or not, ... how to block ?

how to control this traffic ?

btw, users have pppoe
