Hi,

I have a problem, my cisco 831 has one IP a.b.c.d configured on eth0 ,
and e.f.g.h on eth1
Eth0 is connected to our firewll, eth1 to internet.

I put a1.b1.c1.d1 secondary address on eth0, and I want to perform NAT.
I have plugged a laptop on fa3 interface switch of 831, its IP is in
the a1.b1.c1.d1 range.

So from the laptop i can ping eth0 et and ETh1 but not Internet.
I have set
ip nat inside on eth0 , ip nat outside on eth1, and ip nat inside
source list 101 int eth1 overload
access-list 101 permit ip host a1.b1.c1.d2 any

But nothing occurs, sh ip nat trans showes nothing.

i don't if I can set up nat with secondary address
