No communication between FreeRadius and Chilli

[sean]

 Hi,

I have Chilli configured to run on Linksys WRT54G AP. I can access the
Radius server at radius.chillispot.org with no problems. I have
configured FreeRadius to run on a server also running Apache and
MySQL.The FreeRadius installation compiled and runs with no errors and
Radtest works fine, allowing me to authenticate users. The problem is
that Chilli can't communicate with my Radius server. Ethereal tells me
that the destination is unreachable when replying to the Chilli box.

This is part of the Ethereal output:-

The Radius server and the Chilli AP get their IP's from DHCP on a Caymen
DSL modem with static IP. The Modem is 82.141.232.132. The Radius server
is 192.168.1.2 and the Chilli AP is 192.168.1.6, its internal address is
192.168.10.1.

I'd really appreciate any suggestions anyone might have to help me
resolve this.

Regards
