I don't think there are any ports needed to be configure since ports are for WAN to LAN connects and not Wireless connections on the same LAN side.
I would presume that if the 1360 was running in Repeater mode that there shouldn't be anything blocking data traffic between the 1360 and the 655. The only thing that comes to mind is WLAN Partition and if it's enabled and available as an option on the 1360, this could restrict visibility of the 655 from clients on the 1360. However being in Repeater mode, nothing should be restricted as it's just re-broadcasting whats coming and going from the 655.
Is DHCP server still enabled on the 1360. Also are you using static or DHCP as the Connection Type? I would presume that it should be DHCP. I would also presume that DHCP Server should be disabled on the 1360.
