IPv6 through a second proxy¶

For an IPv4-only upstream: destinations with an IPv6 address, dual-stack ones included, leave through the IPv6 proxy, the rest through the first. Neither falls back to the other.

sudo morzer secret set upstream6                  # user:pass@host:port, first
sudo morzer config set upstream6_protocol=socks   # or http; upstream6_tls=true if needed
sudo morzer task run exit-check --output

Needs resolve=gateway (the default). Two providers show as MISMATCH in exit-check, as expected. Off: sudo morzer config unset upstream6_protocol.
