The "recommended" TLS termination companion to Varnish would be Hitch, which is from the same developers. It runs as an independent process and uses the HAProxy PROXY protocol to communicate with Varnish. What this entails Varnish-wise is listening on another port for the PROXY protocol.
Per the Varnish 4.1 documentation, you would listen on both the 6081 (or 80 as the case may be) as well as the internal port, such as 6086
varnishd -f /etc/varnish/default.vcl -a :6081 -a 127.0.0.1:6086,PROXY
You can use the std module to detect whether the origin request came over SSL by doing something like:
sub vcl_recv {
if (std.port(server.ip) == 443) {
set req.http.X-Proto = "https";
}
}
