RevPi connect and IPTables
Posted: 12 Sep 2019, 12:11
Good morning to everyone,
i'm just using a RevPi connect and i need to setup IPTables to perform Source NAT on eth1. The problems is that iptables kernel modules seems to be not present:
so i've attempted to modprobe the needed modules:
but when loading the iptables table modules i'm getting the following error:
and when i check the system log
i get the following entries:
at first time, it seems that modules and kernel version des not match, so i check the infos and the kernel version:
i've performed a system update, but i don't know how to solve this module mismatch..
many thanks,
Pierluigi
