VPN is an IP level facility so you are not generally in need of a tunnel on it. You can tcp or udp on it, unless some firewall in the path blocks it. Then you might be interested in an ssh tunnel for tcp, but ssh does not support udp. You can make proxies move udp packets through the tcp ssh tunnel:

gnunet-vpn
GNUNET-VPN(1) General Commands Manual GNUNET-VPN(1)
NAME
gnunet-vpn - manually setup a GNUnet VPN tunnel
SYNOPSIS
gnunet-vpn [options]
DESCRIPTION
gnunet-vpn can be used to manually setup a VPN tunnel via the GNUnet network. There are two main types of tunnels. Tunnels to an exit
node which routes the traffic to the global Internet, and tunnels to a node that runs a service only within GNUnet. Depending on the type
of tunnel, gnunet-vpn takes different options. The "-i" option is required for tunnels to an exit node, whereas the "-p" and "-s" options
in conjunction with either "-u" or "-t" are required for tunnels to services. For exit tunnels, both UDP and TCP traffic will be redi-
rected. For service tunnels, either UDP ("-u") or TCP ("-t") traffic will be redirected.
The tool will display the IP address for this end of the tunnel. The address can be displayed as soon as it has been allocated, or only
after ("-a") the tunnel has been created.
OPTIONS
-4, --ipv4
Desired IP address on this end of the tunnel should be an IPv4 address.
-6, --ipv6
Desired IP address on this end of the tunnel should be an IPv6 address.
-a, --after-connect
Display IP address only after the tunnel is fully connected.
-c FILENAME, --config=FILENAME
Use the configuration file FILENAME.
-d SEC, --duration SEC
The mapping should be established for SEC seconds. Default is 5 minutes.
-h, --help
Print short help on options.
-i IP, --ip IP
Tunnel should be to an exit node and connect to the given IPv4 or IPv6 IP address. Note that you can specify an IPv6 address as the
target here, even in combination with "-4" (4to6) and similarly you can specify an IPv4 address in combination with "-6" (6to4).
-L LOGLEVEL, --loglevel=LOGLEVEL
Use LOGLEVEL for logging. Valid values are DEBUG, INFO, WARNING and ERROR.
-p PEERID, --peer=PEERID
Name of the peer offering the service to connect to. Cannot be used in conjunction with "-i", requires "-s".
-s NAME, --service=NAME
Name of the service running on the target peer. Cannot be used in conjunction with "-i", requires "-p".
-t, --tcp
Service runs TCP. Either "-t" or "-u" must be specified when using "-s".
-u, --udp
Service runs UDP. Either "-t" or "-u" must be specified when using "-s".
-V, --verbose
Be verbose.
-v, --version
Print GNUnet version number.
