Ciao. Hai provato il modulo ip_conntrack_rpc? Lo trovi in Patch-o-matic.
Dalla descrizione della patch: "This adds CONFIG_IP_NF_MATCH_RPC, which supplies two modules, ip_conntrack_rpc_udp and ip_conntrack_rpc_tcp, which track portmapper requests using UDP and TCP respectively. It also adds the record_rpc match for iptables, which matches if the source of the packet has requested that port through the portmapper before, or it is a new GET request to the portmapper, allowing effective RPC filtering."
si, ma CONFIG_IP_NF_MATCH_RPC gestisce SUN-RPC (aka portmapper), che non ha nulla a che vedere don DCE-RPC o M$-RPC.
