Different IP for client and Server?

hello,

i'm trying make arduino work both client , server @ same time, different ips. want client weather information yahoo api, , want use server chose city. when give them both same ip works when change it doesn't. router gives ips subnet 255.255.255.0, it's ip 192.168.0.1, , want arduino server have 169.254.x.x ip, client won't connect internet unless has 192.168.0.x ip. thats why i'm trying work 2 ips @ same time.

my code follows:

code: [select]

server code w.a. smith
client code webmeister
combined using zoomkat's mixed client/server test code.

any appreciated.

if matters, i'm using arduino uno ethernet shield , sd card, , ide 1.0.5-r2.

you should need 1 ip address. use 192 series one. act public facing server, need configure router direct incoming traffic on port 80 arduino.
