You should be able to use your normal pool and overload command, eg ip nat inside source list 1 pool POOL overload,
You pool, for eg is 192.168.0.60->10.168.0.99, then the first 39 IP's would be used for NAT, and the last will be use for PAT =?iso-8859-1?q?ciscoGo2002?= wrote: > > Hello friends, > > Thankyou for your answeres, but I have more doubts: > > Config: > > ip nat inside source list 1 pool POOL overload > > If have understood your answers, the router start > doing PAT with the first IP address and doesn't takes > the next avalaible public IP address until PAT is > exhausted with the first IP address, right??
