I want to collect Netflow data from routers at remote sites in my Data Center. I have setup Netflow successfully and am receiving data from the devices local to the server. I have Site-Site VPNs to the remote offices and connectivity to the collector is not an issue. I have configured Netflow on the remote routers to use the IP address of the inside interface to source teh Netflow traffic ( also tested with Loopback interfaces) which should make this interesting traffic just like one would for RADUIS or Syslog. The issue is that the traffic generated does not get encrypted. I checked these message boards and have found others with the same issue but no solutions have been found. I can duplicate this issue on 830,1721,3700 series routers with varying versions of code. Does anyone have any suggestions on how to get the data to the server. Any help would be appreciated.
I have this problem too.
