dns server

Can anyone tell me how i would advertise my dns server to the outside world, would I just use a nat statement with the dns port number ?

Re: dns server

Hello this can be done using static NAT.

"

Static translation establishes a one-to-one mapping between your inside local address and an inside global address. Static translation is useful when a host on the inside must be accessible by a fixed address from the outside."

SUMMARY STEPS

1. enable

2. configure terminal

3. ip nat inside source static local-ip global-ip

4. interface type number

5. ip address ip-address mask

6. ip nat inside

7. exit

8. interface type number

9. ip address ip-address mask

10. ip nat outside

----

example

ip nat inside source static 10.0.0.1 200.174.10.100

your internal IP 10.0.0.1 would be reachable from outside, they only need to point to 200.174.10.100 (ip of the outside interface)
