the PS3 may suffer from the same limitations as the AT&T Uverse TV set top boxes. We had a problem with the settop box and the 1522, cause the 1522 will Mask the DHCP servers MAC address on the LAN with it's own. Almost acting as a proxy for the LAN side DHCP. AT&T had issues with this, as the box's would fail to pull DHCP.
I'l have to test it.
