2.4.20-pre7: ip_conntrack: table full, dropping packet.

2.4.20-pre7: ip_conntrack: table full, dropping packet.

[Stephan von Krawczynski]

Hello all,

After several days running kernel 2.4.20-pre7 I came across the syslogged
message:

kernel: ip_conntrack: table full, dropping packet.

This box runs about 10 rules for destination nat. My simple question: is this a
bug, or a need to tune something? If it is a bug, is there a later kernel that
has it fixed?

Hi Stephan. Don't know if you remember me, but we've met at some IN e.V.
meetings in the past ;)

it's not about the number of NAT rules, but the number of connections
going on through your machine.

the FAQ (to be found at www.netfilter.org) describes how to raise the
number of connection tracking table entries.
