Checkpoint MFA with FreeRadius and Google-Authenticator

[stre]

Hello!

I need an advise...

I did install a FreeRadius Server with Google-Authenticator on my DMZ.

Based on this :

https://community.checkpoint.com/t5/General-Topics/MFA-with-Google-Authenticator/td-p/39456

I also did configured the Radius to communicated with LDAP server which is in my internal network.

And It's working fine.

But is it secure ?

What is the best practice with a Radius Server "talking" with LDAP server ?

Should i add another nic on the Radius to communicated with LDAP server ?

Thanks a lot!!!
