Hi,
I tried to:
iptables -A INPUT -p gre -j ACCEPT
But i get:
Unknown protocol "gre" specified.
I try:
iptables -A INPUT -p 47 -j ACCEPT
No failure!
I don't know if iptables don't know the gre-protocol or the kernel. Does
anyone has an idea?
Here my boot, where you can see that all protocols to GRE are loaded:
.....
NET: Registered protocol family 26
u32 classifier
OLD policer on
Netfilter messages via NETLINK v0.30.
