## message authentication algorithm
#auth-algo null
auth-algo sha1

##message auth tag length
#auth-tag-length 10

## Passphrase
## this is used to generate the crypto-key and salt
## this should be al least 30 characters
passphrase RAID_is_nice_but_RAIL_is_cooler

## local ip address to bind to (for tunnel data)
## (if you run an anycast cluster this has to be the anycast ip address)
#interface <ip-address>

## local port to bind to (for tunnel data)
## the number of ports here must be at least as high as the number of
## remote ports defined at the client configuration (in this case 5)
port 8880:8884

## The remote host and port will be learned from the first messages
#remote-host client.unknown
#remote-port 8880:8884

## enable RAIL mode
