Well, an error code of 1 is a progression compared to the 2 you had
before. Error code of 1 indicates that the /sbin/ip command failed and
could not add the route. Proably due to the parameters.

shouldn't that be 
/sbin/ip route add -host $3 mss $2 gw $4 dev $1

According to the manpage for the --up command: 

cmd tun_dev tun_mtu link_mtu ifconfig_local_ip  if­
              config_remote_ip [ init | restart ]

So that 1576 is your link mtu. I believe it is of no use here...
