Hi am am trying to do the ccna skills 4 test, which includes:
frame relay
ppp
eigrp
dhcp
nat
pat
configure static routes.
Everything works fine until I get to NAT and PAT.
Here is the outline:
3 routers = ISP, Sydney, Auckland
ISP>Sydney = Frame relay
Sydney> Auckland = ppp with chap
regarding NAT the tasks are:
NAT to translate the 10.0 addresses to a 192.168.100.0/24. Use PAT to ensure that only the addresses 192.168.100.11 to .20 are translated to.
Use a static mapping of 10.10.0.1 to 192.168.0.1
my nat configs on ISP are
Interface e 0 = 10.10.0.1/16
ip nat inside
int s 0/0 = 192.168.2.1 /30
ip nat outside
access-list 1 permit 10.10.0.0 0.0.255.255
ip nat pool NAT 192.168.100.11 192.168.100.20 netmask 255.255.255.0
ip nat inside source static 10.10.0.1 192.168.100.1
ip nat inside source list 1 pool NAT overload
Sydney has a default route pointing back to ISP, which has also been redistributed to Auckkland.
Any ideas why the NAT dont work.
I cant see why
Thanks
