Re: IPSEC using Linux Kernel 2.6

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Oscar:

Why don't use iptables 1.3.3 and see if the policy match is present
after install the iptables 1.3.3 code into the kernel?

See the kernel options before install the patches ... some patches (as
the documentation said) are *not* compatibles.

Five patches from shorewall.net? 

Why don't try:

kernel 2.6.12
iptables 1.3.3

After that, see If you still needs the patches (from patch-o-matic and
from shorewall.net)

Hope this helps,

Jorge.
