RTNFA Multiple interfaces to capture?

Hi, have just setup netflow on an 857 running 12.4(15)T9 and am confused with the number of interfaces im able to capture. I've enabling net flow individually on both the dialer and the internal vlan1 interfaces and both show two interfaces (Interface 12 & 16 in this instance) to capture from in RTNFA.

Config below

ip flow-export source Vlan1
ip flow-export version 5
ip flow-export destination 192.168.xxx.xxx 2055

interface Vlan1
 ip address 192.168.xxx.xxx 255.255.255.0
 ip access-group xxx in
 ip flow ingress
 ip flow egress
 ip nat inside
 ip virtual-reassembly
 ip route-cache flow

When capturing one interface appear to show outgoing and the other incoming but i cant view a capture of both together? Is this simply a limitation of the free tool?

    You should be able to choose an end point and see all traffic to or from that end point. You would not be able to do that for two separate endpoints at the same time.

    well i have a problem then as when i choose an endpoint i only see either inbound or outbound traffic depending on which interface i originally selected to capture.

    if i capture <IP ADDRESS>, Interface 12 I see inbound traffic. If i capture from <IPADDRESS> Interface 16 I see outbound traffic.

    That sounds like a configuration issue. In order to be more helpful we would need you to PM us the full config, packet capture, and captured flow being sent to the device hosting the NetFlow Realtime free tool. Also include a description of your settings.
