I'm trying to setup a RB450G(ros 5.24) with PPTP VPN/RSA SecurID token authentication. PPTP connectivity works with local user authentication, but errors out with RADIUS. I've enabled AAA authentication for router admin login and I can telnet into the RB450G fine:

When I try PPTP with AAA I get this:

Anyone have experience with RSA Authentication manager to know what my problem might be?

Seems like your radius server is not set to allow dial in / vpn connection type for the username you're providing.

Nice post man ! hope you will be do better in future with more informative ideas and information . Thank you

I'm quite sure the authentication server is not set to allow NAS-Port-Type = 5 for the username provided. (This is just another term for telling the same as I did on april 24th)

Turns out the RSA RADIUS server we're using only supports PAP, EAP-PEAP-GTC, EAP-TTLS-PAP, and EAP-TTLS-GTC protocols for authentication. I'm guessing when I telnet in it uses PAP?

If it set both the PPTP server and client to use PAP, it works! BUT VERY INSECURE! Looks like the Mikrotik VPN servers only support PAP, CHAP, MSCHAP1, AND MSCHAP2 authentication protocols.

Any way to make this work beside PAP?
