Hi there,

have a pix (525, 6.3.3) securing a public class-C network /24

Want to get data in and out only based on ACL.
So want to have this /24 network staticly mapped with no network
translation whatsoever

Something like
static (inside,outside) zz.yy.xx.0 zz.yy.xx.0 netmask 255.255.255.0 0 0

This is accepted, but seems of no use ( perhaps getting from a higher
security interface to a lower).
However a nat 0 rule works for that also

However when I do

static (inside,outside) zz.yy.xx.1 zz.yy.xx.1 netmask 255.255.255.255 0 0
static (inside,outside) zz.yy.xx.2 zz.yy.xx.2 netmask 255.255.255.255 0 0
static (inside,outside) zz.yy.xx.3 zz.yy.xx.3 netmask 255.255.255.255 0 0

etc, etc, it does work. I can get from a lower security device to a higher
security device.

Since I also got a lot of ( virtual) interfaces, this mean 256 times all
the interfaces, is a lot of rules.

I guess i miss something obvious then, don't I?

Thanks for your time

Jan-Willem Michels





I have tried outgoing a nat null rule and with incomming static rules
