IP Pool for Ethernet

we indeed already tried sending only the Framed-IP-Address in the Access-Accept and it didn't work, the Gateway didn't assign this address to the IPsec client, but a default IP address.

I also didn't understand why the Framed-Pool attribute is a must in the Gateway,
Juniper supports only the following cases (extract from the Screen OS documentation):

Case 1:  Framed-Pool attribute and the Framed-IP-Address attribute are both included in the Access-Accept message.
=> The Framed-Pool attribute is always ignored by the RADIUS server unless the  framed-IP-Address value is 0xFFFFFFFE ( Then, the device allocates an address from the Framed-Pool attribute sent by the RADIUS server

Case 2: Framed-Pool attribute and the Framed-IP-Address attribute are both absent from the Access-Accept message.
=> The device does not assign an IP address to the end user.

Case 3: Framed-IP-Address attribute is included in the Access-Accept message and it has a value of 0xFFFFFFFE ( BUT Framed-Pool attribute is absent.
=> The device allocates an IP address from the default IP address pool that is configured for that virtual system.

Case 4 : The pool sent out in the Framed-Pool attribute is not configured, or it does not have any IP addresses.
An error messages are generated and the negotiation is terminated.

Best regards,

That doesn't make sense. You can't send it a specific IP, and an 
attribute telling it to pick an IP from a local pool, and expect any 
sensible behaviour.

Have you tried just sending the Framed-IP-Address?

Also, your subject line is wrong - this is nothing to do with "Ethernet"
