Hi Swinogers
since a few weeks i see following messages
on a server in Europe
kernel:nf_ct_sip: dropping packetIN=eth0 OUT=
MAC=00:23:54:d7:7c:12:80:71:1f:e2:71:81:08:00 SRC=191.189.9.153
DST=62.75.177.146 LEN=513 TOS=0x00 PREC=0x00 TTL=115 ID=27879 PROTO=UDP
SPT=29012 DPT=5060 LEN=493
There are various IP´s causing this problem.
In common: all IP´s causing those Messages are originating from a CGN
Gateway
The example above is an Brazilian Cableprovider.
Client behind those networks complaining getting sometimes dropped
calls, or one way speech in some cases not able to Register some of
Sip-devices while others work. mostly in times the Kernel drop packets.
Does someone have any idea what is causing this ? even why the hell an
invalid MAC address could made it so far.
