I have one root server and two clients. The root server has a static ip address and runs Debian Linux. My clients are Mac OS X and Debian Linux with dynamic ip addresses.
From my clients I can open a vpn connection but the traffic is blocked by Shorewall. The Shorewall log told me that the traffic comes from net zone to fw zone (fw is the server zone, I don't have a local zone because it is only one machine) but it should be from vpn zone to fw zone or not?
This is one line from the log:
net-fw:DROP:IN=tun0 OUT= SRC=10.8.0.3 DST=10.8.0.1 PROTO=TCP SPT=37744 DPT=3000
And this are my config files:
openvpn server.conf:
port 1194
proto udp
dev tun
ca ca.crt
cert me.crt
key me.key
