Hi all, I'm new to this list, having only got my netfilter box working yesterday. I'm seeing occasional bunches of
kernel: Neighbour table overflow in the logs. Is the size of this table (wherever it is) controlled by: net.ipv4.neigh.default.proxy_qlen or net.ipv4.neigh.eth0.proxy_qlen net.ipv4.neigh.eth1.proxy_qlen or neither or both? Will sysctl -w on these take effect on a running firewall or do they have to be added to /etc/sysctl.conf and a reboot performed? The current value is 64. What is the impact on the system of increasing this to, say, 128? Apologies if this is documented somewhere. I havent found it in any of the network/netfilter HOWTO's yet. Cheers, Terry.
