This seems to be old config directive.
New corresponding one shoud be "ssl_bump bump net_bump"

And, no "peek" one? Or that's the problem?

Thanks.

I also tried such config.
With such "http_port" and "http_port intercept" with ssl-bump at last.
Although curl works under test, the certificate is not the fake one.
(Issuer is not my fake one)
So I consider the ssl-bump not working in that case.

I'd like to reply when I set it up later to test.

Thanks
