Topic: No return traffic to wireless clients

hey all,   

I've recently setup a chillisoft installation, fairly generic with changes only to the radius, uamallowed & uamserver sections of the config.  The authentication bit works,  and the redirection to tha UAM homepage and CGI works great as well.  However the enduser browser page times out after the redirection. I try to ping from the wireless workstation (192.168.182.2) I observe the following:

1) Ping to the chillisoft gateway tunnelled interface works (tun0) - tcpdump sees icmp echo requests/replies
2) Ping to the chillisoft gateway LAN/Internet-bound interface works (eth0 - 10.56.50.158/28) - tcpdump sees icmp echo requests/replies

    ** note:  eth1 was brought up without any address **

3) Ping to the gateway of the eth0 interface (upstream - 10.56.50.145/28) FAILS - tcpdump on eth0/tun0 sees icmp echo requests but no replies.  The gateway sees the requests but is not able to arp the workstation (15:16:45.776925 arp who-has 192.168.182.2 tell svcdns).

Can someone shed some light? I'm running chillispot 1.0


cheers
