the 0.0.0.0 simply means 'don't nat'.

We would need the config to see what's going on.

Also, is the entry non-zero initially and then switching to 0.0.0.0 ?

Does it break any connectivity ?

Could you capture a sniffer trace of a failure.

Is it happening for specific client or all of them ?

All the time or just sometimes ?

Thanks,

Gilles.

Hi Giles,

After checking the active CSS I can find the same 0.0.0.0 so I guess you can use the showtech.out of this box as well ;-)

Attached you can find the showtech.out and the show flows output.

many thanks in advance
