[strongSwan] A little help with the configuration

I have some news, looks like originally the connection wasn't really establishing. What I did to solve is removing the pool.
Now the connection works correctly, but the only thing I'm missing is setting our company DNS. As you can see on that pool I tried setting those DNS servers (it forces me to set "addrs" value, I really don't need it).

What should be the correct way to set DNS? I have no idea why the connection fails with that pool.
