I’m using OPNSense with Zerotier plugin. All good except speed is very slow.
I checked zerotier-cli peers
and it looks like this
the b015
is the client (my phone)
So, is it possible to get a DIRECT connection if I’m behind CGNAT?
I also saw this link docs(dot)zerotier(dot)com/devices/opnsense/
ZeroTier clients behind OPNsense#
If you have computers behind an OPNsense router, they probably won't be able to make make direct, peer to peer ZeroTier connections. pf based routers use Symmetric NAT otherwise known as Endpoint Dependent NAT. This is unfriendly to any peer to peer protocol.
Here are some options:
UPnP/NAT-PMP#
ZeroTier will use UPnP or NAT-PMP if they are available.
Obviously UPNP will be useless as I’m behind CGNAT. Is there any other way?
