any guide/script for masternode setup on vps maybe mutliple nodes with ipv6?
btw link on op to website shows 404 page not found error:

Not exactly the most active dev team out there. Well, not active since may or so XD
I tried to make a IPv6 multiple installation with the help of mersmsxn (sorry, I know I always write horribly wrong your nick

) but there is something inherently wrong with the wallet which avoid us of getting it.
Salute
I had success with the following conf settings (relevant parts bolded):
rpcuser=eternityrpc
rpcpassword=x
listen = 1
rpcport = (something)
daemon = 1
server = 1
gen = 0
discover = 1
eternitynode = 1
externalip = [ipv6]:4855
eternitynodeaddr = [ipv6]:4855
bind = 127.0.0.x
bind = [ipv6]
eternitynodeprivkey = xxx
bind should be the ipv6 address AND a loopback (127.0.0.1-255, different for each instance). This means you can have no more than 255 instances running on a single server, though I doubt that will be a problem. Also each node should have a different rpcport just in case. Each instance should also run on a separate user account.
The local conf file should include [ipv6]:4855 as the bind address.
If that doesn't work, check to make sure that the ipv6 addresses are actually bound (ifconfig). Many hosts offer ipv6 but activate it only by manual request.
