Once you have two NATs, you can either try to punch holes (ZeroTier tries that), use UPnP (ZeroTier does - see below) or relay traffic using dedicated machines

Once you have two NATs, you can either try to punch holes (ZeroTier tries that), use UPnP (ZeroTier does - see below) or relay traffic using dedicated machines (ZeroTier does that as fallback). I successfully used ZeroTier to connect multiple devices behind NATs.
VPNCloud seems to only do UDP hole punching and doesn't have the ability to relay via a third party. At least in theory, ZeroTier should handle cases that VPNCloud doesn't.
- Anunayj 6y agoI think zerotier does UPnP too (read somewhere), though I could not get zerotier to work reliably with 2 NATs. I'll try this and tell if I see any success with this.
- dividuum 6y ago> I think zerotier does UPnP too I think you're correct. Thanks. My information was from an old blog post from 2014 [1] but they seems to have added support since then: https://github.com/zerotier/ZeroTierOne/commit/bf193dd3 https://github.com/zerotier/ZeroTierOne/commit/bf193dd3.
