Hi everybody,
First of all a big thank you to chillispot devs!!

And then:
I got a configuration where a chilli 1.0 works but chilli-1.1 does not.

Clients get DHCP lease no problem.
Routes are ok, with version 1.0 everything works like a charm
With 1.1 I just get a lot of:
Received packet with no destination!!!
cb_dhcp_data_ind. Packet received. DHCP authstate: 5
cb_tun_ind. Packet received: Forwarding to link layer
Received packet with no destination!!!
cb_tun_ind. Packet received: Forwarding to link layer

I had the same issue and was aparently related to MTU, so depending on where the hotspot was (different locations and internet connections)
I had to change tun mtu between 1460 and 1492.
Now packets do not arrive from chillispot to the client. With tcpdump I see chilispot box sending the packets (icmp replies,UDP DNS queries) all right but they get lost in the air : )
ARP and DHCP packets are fine, ICMP TCP and UDP just get lost. With the exact same box/conf everything works with version 1.0

Is there something I'm missing? What could be causing this?
I got the 1.1 working with Ventura27's patch ....

Thank you very much
Daniel

PD: I want to switch to 1.1 because of random core dumps  on some childs and few timestamp,userurl variable problems in 1.0
