You can make the currently selected peer address available as an nginx
variable, then use the "map" directive to compute the per-peer bind
address, like follows:
map $peer_addr $bind_addr {
192.168.1.100 192.168.1.1;
2001:0db8::100 2001:0db8::1;
...
}
or like this:
map $peer_addr $bind_addr {
~: 2001:0db8::1;
default 192.168.1.1;
}
Hint: the "proxy_bind" directive supports variables.
