Hii all gurus.. given the following configuration, i would like to pubish one lan computer to internet as webserver with 192.168.0.9 (125.16.132.cc). For that there is no problem as such while request are coming inside...(shows 125.16.132.cc) but while gong out of webserver, it gets natted to one of the nat pool i.e., either 125.16.132.aa or 125.16.132.bb . what i need is i want to saparate a range of lan ips say, 192.168.0.1 to ..10 in a different acl which will nat to their own static ones, so that DNS can do reverse lookup correctly. Pls guide me through..... TIA.... interface FastEthernet0 ip address 192.168.0.1 255.255.255.0 secondary ip address 125.16.132.xx 255.255.255.240 ip nat inside speed auto ! interface Serial0 ip address 59.145.65.xxx 255.255.255.252 ip nat outside ! ip classless ip route 0.0.0.0 0.0.0.0 Serial0 ! no ip http server ip nat pool ittinalan 125.16.132.aa 125.16.132.bb netmask 255.255.255.240 ip nat inside source list 101 pool ittinalan overload ip nat inside source static 192.168.0.9 125.16.132.cc ! access-list 101 permit ip 192.168.0.0 0.0.0.255 any !
