Netflow receiving

[vitaprimo]

Can OPNsense receive Netflow data from external sources?

I added it as a Netflow collector on a vSphere Distributed Switch using the default port number it prepopulates (2056) and added a NAT rule to redirect to the prepopulated address as well, since it's 127.0.0.1. I figured otherwise it would not reach it.

I just did this, but so far I've seen no difference. OPNsense is a secondary firewall, it doesn't have a direct connection to anywhere on the network, it's only connected to an isolated virtual switch for which the only exit is through another firewall, any traffic/data should be fairly easy to spot.

Thanks.
