Iptables and dpts:ipcserver:65535

Hi list, just check the output of iptables -L -v on a new box and saw an entry Chain input_ext (1 references) 307 35343 ACCEPT tcp -- any any anywhere anywhere state ESTABLISHED tcp dpts:ipcserver:65535 flags:!SYN,RST,ACK/SYN with 35343 transferred bytes against an ipcserver at port $ffff. Is it what i think - an interprozess (interchain) communication of netfilter - or should i be worry about that. Yours Michael
