(0000761) dloper (administrator) 2013-03-22 15:59	This is also the case for ClearOS 5.x when hosts are part of the network and are assigned to 1:1, they are unable to reach hosts in the TUN network. What is happening here is that the source packet is being nat'ed to the address in the 1:1 nat such that the host in the tunnel receives the packet with the public IP address represented in 1:1 instead of the internal IP as the respond-to address. The host then replies but NOT in the tunnel and the packet is received by the 1:1 alias address and is dropped because of a state violation.
(0000762) user2 2013-03-22 20:40	The firewall has some special rules to handle NAT policies for IPsec VPN. These same rules likely need to be applied to OpenVPN tunnels as well.
