I have just received my new Ant S1's trying to connect them to my node on the local network  I have setup the following 3 pools

Pool 1 192.168.1.20:9332
Pool 2 100.166.178.107:9332
pool 3 us2.eclipsemc.com:3333

but when the S1 connects is goes straight to pool 3 why won't it connect to my node on the local network, under the mining status tab the first 2 pools aren't in the list only pool 3 as alive, is there a setting I have missed.
