Re: [Radiusplugin-users] Framed-IP-Address problem

[Ralf Lübben]

Hi,

the plugin just writes the Framed-IP address to the client config file (maybe 
as 
your client config script does) if it gets one from the radius server.

One option could be not to send to the Framed IP option another option could 
be to do the address selection at the radius.

Overall, I think the behavior of a script and a plugin a very similar.

If you have further question please let me know.

Ralf
