ip assigned from radius + access to proxy

Wannabe · Tue Apr 08, 2008 7:28 pm

Hello,
I have the following network schema:

 --| ADSL modem |------| HUB |------| mikrotik |-----     hotspot
         192.168.0.1     |      192.168.0.2  192.168.1.1   //192.168.1.0/24 clients network//
                         | 
                         |
                         | 192.168.0.3
                     |Proxy+Radius|

   //192.168.0.1/24 internal network//

For each client, authorized through Hotspot service on Mikrotik, the radius-server assign an IP-address from pool (e.g. from 192.168.2.2-192.168.2.254). All HTTP-traffic from Hotspot clients goes through my transparent proxy-server.

My problem: I cannot set properly the IP pool parameters that must be assigned from radius-server to client, that the client with this assigned address must be able to access to proxy-server without using NAT on MT. (In my case I cannot use NAT on external MT's interface because in my proxy-server's logs must be shown a client's IP assigned from Radius).

Please give me advice which radius' ip-pool configuration can be used in such case (example pool, netmask etc.) or (probably) how internal network must be reconfigured.

Thanks.
