#################### The Problem ################################
I have discovered that with net.ipv4.ip_forward = 1
the apr table starts to grow and grow and I think I get an arp table
overflow. Also I get No buffer space available errors. When I do
net.ipv4.ip_forward = 0 the arp table reduces to a normal size and the
No buffer space available errors stop.
Any ideas?
Thanks.
