[Openvpn-users] tls-auth errors??

[Nik <openvpn@xxxxxxxxxxxxxxxxxxx>]

Hi All,

Following on from my multi-client tests, I found a reference in the rel 
2.0 documentation to using the [direction] option on the --tls-auth 
parameter:

# The server and each client must have
# a copy of this key.
# The second parameter should be '0'
# on the server and '1' on the clients.
;tls-auth ta.key 0 # This file is secret

My configuration works both with and without the [direction] option.

However, whenever I set the [direction] as specified above, I get the 
following errors in the server's log immediately upon connection from a 
client, and then sporadic further errors (see timestamps): The addresses 
192.168.0.xx:1194 and [192.168.0.xx] are identical.

source address from client [192.168.0.xx], packet dropped

Further testing has revealed that when the [direction] is not set, the 
initial errors don't occur, but the sporadic ones are still occuring.

I am *fairly* sure there is no device on my network trying to 
impersonate my machine, so I am wondering what the errors imply?

All replies appreciated.

Cheers!
Nik
