These things suck at the best of time and frequently don't play nicely with Linux. With OpenSUSE I take it you're using network-manager as your management tool for wifi? Take a look here to save me typing out something similar: http://unix.stackexchange.com/questions/89630/how-to-sign-into-an-open-wireless-network In short, you might have to prod it with wireshark a little to see exactly what kind of redirect it's attempting to perform on you. Easier would be to try and connect to the SSID first via network-manager and then, before you try and actually access the network, look at what ifconfig/ ip addr/etc tell you has happened to your network setup. See if you can ping out, or if your resolvconf has updated properly. As ever, one step at a time and a bit of logic and perseverance will usually get to the bottom of it.
