IP Routing Question

Help! I have a PC router connecting an Ethernet LAN to a Token Ring LAN. The PC rtr has 2 NICs one for each LAN. The PCs on the Ethernet segment connect via the rtr to an AS/400 on the TR segment via a static route set up on the AS/400. The PCs on the TR segment connect to a remote AS/400 which the PCs on the Ethernet segment NOW need to connect to but can’t. The TR sement PCs connect to the remote site via a Cisco rtr. Is there a way to allow the Ethernet PCs to connect to the remote AS/400?
