Hello,
I have a communication between 2 machines:
SRC-Port: 52451
DST-Port: 49153
If I start Kerio, the communication will be lost. I have no traffic rule which blocks this port: Service = any : allow
Is there an other functionality in Kerio control which could block my communication? All settings ar on default value.
Best Regards
Gerd

try the following,
source: any,
destination: firewall
service: port 52451, 49153 (whether TCP or UDP)
action: allow
translation: put 192.168.1.2 in destination NAT
hope it helps...

Just tested with Kerio Control 8.1.0 Virtual Appliance with Netcat on TCP 49153 with your described environment and it works (There are lots of rules on my firewall)
On workstation
-------------------------------
ubuntu:~$ nc -vv -l 49153
Connection from 172.20.0.254 port 49153 [tcp/*] accepted
hello
On Kerio Control
-------------------------------
~ # nc -p 52451 172.20.0.100 49153
hello
A review of the traffic rule would be recommended.

These are 2 Windows Machines, its an OPC connection (OLE for process control)
I found out with the Kerio Debugger, that the OPC Server does not Support 3Way Handshake.
After disabling 3WayHandshke in Kerio it was working but after a reboot from the Machine which Kerio is installed, the communication is blocked again. Then I restart Kerio and it works again.
I have no idee what could be the problem, the debugger in Kerio (Filter:Show packets which are dropped for som reason)does not display dropped packages.
