[Chilli] CoovaChilli 1.2.9

Sat Feb 4 19:34:37 UTC 2012

Hello!

I am still trying to fix anyip feature on my Chilli. I've analized TCP 
stream when opening captive portal web page and I get:

592	117.787866	10.9.0.4	10.9.0.1	TCP	66	49713 > http [SYN] Seq=0 
Win=8192 Len=0 MSS=1460 WS=256 SACK_PERM=1

596	117.789533	10.9.0.4	10.9.0.1	TCP	54	[TCP Dup ACK 594#1] 49713 > http

598	117.790719	10.9.0.1	10.9.0.4	TCP	60	http > 49713 [RST] Seq=1 Win=0 Len=0

10.9.0.4 is client IP
10.9.0.1 is chilli server

I can SSH from client to server without problems, only web pages on 
10.9.0.1 don't work.

Any idea, why I get "TCP Dup ACK" and then RST ? What am I missing. Any 
idea?

Could it be realted to this (duplicate entry in Unit 0 and Unit 1), when 
I execute chilli_query listippool

 > Unit 0 : -inuse- : 10.9.0.2 : mac=02-01-01-05-01-01 ip=10.9.0.2 age=1
 > Unit 1 : -inuse- : 10.9.0.3 : mac=02-01-01-05-01-01 ip=10.9.0.2 age=1

Problem exists only if I enable anyip feature and if I use DHCP on my 
client. When I use static IP (anyip) on client, it works OK.

Thanks, Bye
