My Balance One Router is using 2 PepVPN Connections and that’s the max for that. Can I use LT2P IPsec as well and how many connection am I allowed?
For the Balance One you can get a license to extend it to 5 peers ($99) or 10 ($199). See PepVPN licenses.
Two IPSEC tunnels could be created in parallel PepVPN tunnels without licence.
