ip nat outside

I need help to understand "ip nat outside" in the Serial1/1.4

How i can do troubleshooting over that.

interface Serial1/1.4 point-to-point

ip address 192.168.150.93 255.255.255.252

ip nat outside

no cdp enable

frame-relay interface-dlci 120

interface FastEthernet0/0.50

encapsulation dot1Q 50

ip address 172.17.3.2 255.255.255.0

ip nat inside

!

interface Serial3/2.45 point-to-point

bandwidth 128

ip address 10.10.26.2 255.255.255.252

Not sure what you are asking. The "ip nat outside" under s1/1.4 is matched to "ip nat inside" under fa0/0.50. Using one of your NAT statements as an example -

ip nat inside source static 172.17.3.138 192.168.200.2

this says when a packet from 172.17.3.138 arrives on the fa0/0.50 interface and is routed out of the s1/1.4 interface it is Natted to 192.168.200.2.

Has this helped ?

The "ip nat outside" causes the same behavior in the interface Serial3/2.45 with the interface fa0/0.50?

Jon Marshall · ‎01-08-2009

Yes it will if the traffic is routed out of the s3/2.45 interface although whether you want it natted to a 192.168.x.x address is another matter.

This command, has some effect?, taking into account that the interface to which this associated the ip nat inside is the interface FastEthernet0/0.50?

ip nat inside source static 172.17.210.12 192.168.200.3
