The client's connection to the destination is an ordinary end-to-end connection arriving from the exit gateway's IP. Per-packet unlinkability in transit does not become request unlinkability at the destination.
With a fixed exit, P2 behaves like the single dVPN exit case. Rotate the exit per request to restore it.
Per-packet timing (hampered by mixing delays and cover traffic)
Residual / countermeasure
How far bulk transfers of many packets can be correlated over time is an open question. The mixnet is strongest for small, independent messages and weakest for bulk transfers.
Pros
Client IP heavily obfuscated (timing + location) by the Nym network
Cons / mitigations
Slow (5-hop + mixing delays)
A fixed exit gateway is a linking key at the destination
Fit
Client identity and IP heavily hidden from the destination
Not for bulk or latency-sensitive transfers
Verdicts and the latency implied by the path are an illustrative model, not measured values.
