NAT

[fbadr]

Dear all

i have a problem with natting

router is 1601 version 12.2

my config is as follow:

interface ethernet

ip address xx.xx.xx.xx 255.255.255.0

ip nat inside

interface serial0

ip unummbred e0

ip nat outiside

ip nat inside source list .......

ip nat list .... pool .... overload

access-list 1 permit 192.168.10.0 0.0.0.255

it didnt work i dont know why.

in the show ip nat translation i can see the translation but nothing goes beyong the router.

is it because the serial interface is unummbred i dont know?

please help

tks

T what ip would you be overloading as you are using an unnumbered interface ?

I think you should try with a loopback in between with a route map, but im'n not sure about this since i've never done nat in a situation like this.

tks

i am using one IP of same subnet of the ethernet for the overload

could you be more specific about loopback what you mean?

route map i dont think it will solve it although i will try

any other suggestion?

tks

Hi Fadi,

Good Day! :-)

Can you please try the following configuration.

interface loopback 1

ip address yy.yy.yy.yy 255.255.255.0

interface ethernet 0

ip address xx.xx.xx.xx 255.255.255.0

ip nat inside

interface serial0

ip unummbred loopback 1

ip nat outiside

ip nat inside source list 1 interface ethernet 0 overload

access-list 1 permit 192.168.10.0 0.0.0.255

is there any command like ip nat everything 0.0.0.0 0.0.0.0 if port 25 or 110 to 10.0.0.1

I mean can i redirect tcp ports 25 and 110 to inside address ?

If you are seeing the translations, but it is not going out, check that your routes are well configured. Do not forget to check for the route for the address you are nattin to. To redirect to a port use the static nat translation

i.e

ip nat inside source static tcp

Don't know if you got this working but check the spelling of "outiside" - should be outside. Perhaps this makes the difference? I'm in no way an expert just happened to be reading the configuration and saw the misspelling
