Your Antminer probably can't reach the internet. Do you have any devices that can actually reach the internet from that subnet? Just change its IP address to something from within the 192.168.0 subnet such as 192.168.0.99.

Edit: Forgot to add that you will probably want to go into your router and permanently assign that IP address to your Antminer's MAC so there won't be any conflicts.

Use the address stratum.bitcoin.cz:3333 for Pool1
Use the worker style of  "Leooo.worker1", where "Leooo" is your registered user name and worker1 your registered worker. The password of worker1 has to be consistent with what you registered on Slush's pool (check Slush's instructions).
These entries have to be precisely what the pool requires, no additional 'spaces' or 'variations'.
There is no point in having 2 entries into the same server on the same pool.

Cheers
