Collector Software for NAT Translations Logging

[schwarzenbachcyb]

I need to log my NAT sessions and like to use the "High-Speed Logging of NAT Translations" with "ip nat log translations flow-export v9".

https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_nat/configuration/xe-16/nat-xe-16-book/iadnat-hsl-vrf.html

Does anyone has a recommendation for the netflow collector software? It should be open-source, running on linux and include a GUI or CLI-commands to search for specific translations.

Can I use nfsen/nfdump or better something else?

Thank you for any hint.

Hello,

have a look at the link below:

Thank you for the link. But I need to know, which of them understand the NAT flow packets from the cisco device. nfsen/nfdump don't do it...

They are no "normal" netflow packets...
