NethServer Version: 7.3.1611
I set up access through RDP (3389). But after the connection, I got the error "connection lost" and I can not connect any more. In the logs appears an inscription
Shorewall:net2fw:DROP:IN=eth1 OUT= MAC=00:хх:хх:хх:00:00:00:хх:хх:хх:01:хх:0х:00 SRC=176.ххх.х00.ххх DST=ххх.ххх.ххх.ххх LEN=1260 TOS=0x00 PREC=0x00 TTL=115 ID=22431 PROTO=UDP SPT=56823 DPT=3389 LEN=1240
I read http://shorewall.org/FAQ.htm
(FAQ 85) Shorewall is rejecting connections from my local lan because it thinks they are coming from the 'net' zone.
I'm seeing this in my log:

Answer: This occurs when the external interface and an internal interface are connected to the same switch or hub. See this article for details. The solution is to never connect more than one firewall interface to the same hub or switch (an obvious exception is that when you have a switch that supports VLAN tagging and the interfaces are associated with different VLANs).
Perhaps this is my case? But I can not understand what I need to do?
