Chained Proxy (relay)
The relay proxy group used to chain traffic through multiple nodes in sequence, but it's now deprecated — use dialer-proxy for chained proxies instead.
The relay proxy group is deprecated — use dialer-proxy for chained proxies instead. dialer-proxy is more flexible: it supports proxy providers, lets you configure the relay relationship per node, and isn't affected by the internal latency-testing logic.
Why It's Deprecated
The relay proxy group forwards traffic through each node in the group in sequence, supporting only TCP forwarding or UDP-over-TCP forwarding. It has two clear limitations: it doesn't respond to the group's own latency test results (you'd need to configure a separate benchmark-url for testing), and it can't be combined with proxy groups for flexible dynamic switching.
If you're maintaining an old config that uses relay, see the relay migration section on the dialer-proxy page for a migration guide and examples.
