[OSL | CCIE_RS] Vol2 Section12 Task9.3 NAT - mistake in PG?

[Roger RPF]

Hi Guys,

 

I think there is a mistake/typo in the PG of task 9.3 of Vol2, the NAT
configuration. The PG shows here a mix of “old school” nat and nat with nvi.

Old school part:

 

R8:

ip nat inside source list 8 interfaces serial0/0/0 overload

access-list 8 permit 192.168.80.0 0.0.0.255

 

than on the interfaces nvi style:

 

int s0/0/0

ip nat enable

!

int fa0/0

ip nat enable

 

Well, since I’m not really an advanced NAT user, I was confused about the
mix in the syntax so I wanted to try. Well, with this configuration I never
got a translation done. So after reading the DocCD I changed the nat part
to:

 

ip nat source list 13 interface Serial0/0/0 overload

 

and it worked fine. The other possibility which I figured out was to
configure under the interface the old style of nat and leave the other
command as it was:

ip nat inside source list 8 interfaces serial0/0/0 overload

int s0/0/0

ip nat outside

int fa0/0

ip nat inside

 

Am I right with what I’ve figured out? Could it be possible that there is a
small typo in the PG?

 

regards
