Hoping to get some help. I've got a PPTP vpn setup on an RB450 (3.28). I have no problems with it using defined Secrets in the Mikrotik, but am having nothing but problems using Radius.

Initially I have been getting the error "terminating... -could not determine a remote IP address"

The default profile that the PPTP server is set to use has "Remote IP" set to the DHCP pool of "vpnpool"

I tried setting "framed-pool" in the Radius user to "vpnpool", but am now getting an error on the PC: "TCP/IP CP reported error 738: The server did not assign an address."

What am I missing?

What RADIUS server are you using? MikroTik User Manager, FreeRADIUS, or..?
I had to use "Framed-Pool" (not "framed-pool") to get this to work on my hotspot. FreeRADIUS (my version anyway) did not recognize the lower case start characters, and would not send it.

steel belted radius

*to add* the attribute is set to "Framed-Pool" in the radius server

I think Steel Belted has radtest. On radius server shell
radtest user password 127.0.0.1 0 radiussecret

That is a zero following the ip address. Change user, password, and the radius secret to yours.
Does it return the "Framed-Pool" attribute with that user?

You need to set the Local IP in the PPP Profile as well. You can't specify Local IP via Radius, only Remote IP can be a pool or via Radius.

That did it. Thank you!
