Adrian, Please tell me which version of nfdump and nfsen are you referring to?
Unfortunately because an incompatibility between latest nfsen/nfdump and latest rrdtool 1.4.x (in RHEL 5), I have to use nfsen 1.3.2 with nfdump 1.5.8 and older rrdtool 1.2.x :( I got "Filter error: line 1: syntax error at 'router'!", with simple syntax "router ip 172.0.0.1" This feature should have been implemented in newer versions. I'll think about another way to work around. Thank you anyway!
