I have a really odd issue with Flow Rules: it seems that they do not work?!
If I put anything but
accept; at the end of my rules, traffic gets blocked.
I started using statements that included
ipdest, none of these rules worked. So I came up with this example: it should allow ICMP (0x01), UDP (0x11), and TCP (0x06):
accept ipprotocol 1; accept ipprotocol 6; accept ipprotocol 17; drop;
But even in this simple example all traffic is blocked.
I think I need some help here …
