FYI, the access list in our case did NOT stop traffic on those ports. Cisco doc said it only stopped traffic TO the router not THROUGH the router. Useless. YMMV. The above two rules I quoted are probably your problem. I think either the AS/400 or the Perle may ping before attempting to connect. I found no docs to support that, but removing that block solved our problem. A better bet is to start logging packets somewhere (somewhere depends on your network setup, I used our firewall) and get the computers cleaned and patched. Good luck!
