DUO 2FA integration with FreeRadius

I use Duo 2FA with FreeRadius for CLI access to some network devices. I’m not aware of a away to do it without using the DUO proxies.

It gets tricky when specific devices are expecting VSA’s in the access accept message and you also want 2FA. I’m currently hijacking a standard radius attribute to store device info so it gets passed through the Duo proxy.

Its a hack and I don’t like it, but it works.
