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:- No. Time Source Destination Protocol Info 540 142.622909 192.168.1.6 82.141.232.132 RADIUS Access Request(1) (id=0, l=195) Frame 540 (237 bytes on wire, 237 bytes captured) Ethernet II, Src: 00:12:17:b7:a1:71, Dst: 00:00:c5:b1:0c:0c Internet Protocol, Src Addr: 192.168.1.6 (192.168.1.6), Dst Addr: 82.141.232.132 (82.141.232.132) User Datagram Protocol, Src Port: 2051 (2051), Dst Port: radius (1812) Radius Protocol No. Time Source Destination Protocol Info 541 142.623743 82.141.232.132 192.168.1.6 ICMP Destination unreachable Frame 541 (70 bytes on wire, 70 bytes captured) Ethernet II, Src: 00:00:c5:b1:0c:0c, Dst: 00:12:17:b7:a1:71 Internet Protocol, Src Addr: 82.141.232.132 (82.141.232.132), Dst Addr: 192.168.1.6 (192.168.1.6) Internet Control Message Protocol 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 Sean
