Subject: Re: Patch for H323 connection tracking for kernel 2.6.14 and Panic with SIP tracking

When making a call:

# cat /proc/net/ip_conntrack_expect
174 proto=17 src=217.66.118.164 dst=80.126.43.45 sport=0 dport=7071
174 proto=17 src=192.168.1.1 dst=192.168.1.2 sport=0 dport=8000

tcpdump:
13:05:46.220869 IP 192.168.1.2.8000 > 192.168.1.1.7072: UDP, length: 172

syslog:
Jan  6 13:05:46 sanctorium kernel: vrmr: REJECT reject-in IN=eth0 OUT= 
MAC=aa:00:04:00:0a:04:00:90:27:57:31:29:08:00 SRC=192.168.1.2 
DST=192.168.1.1 LEN=200 TOS=0x00 PREC=0x00 TTL=64 ID=401 DF PROTO=UDP 
SPT=8000 DPT=7072 LEN=180

REJECT is the default policy for lan to firewall traffic.

Can it be that the expectation direction is wrong?
dropped traffic is src 192.168.1.2:8000 to dst 192.168.1.1:7072
expect is src 192.168.1.1 to dst 192.168.1.2:8000

On the other hand, the dropped traffic looks the same as the 
expectation, only in the opposite direction...

Regards,
Victor
