Squid transparent proxy + HTTPS

wndrew

@JonathanLee What do you mean? I need access to those sites. What's may be the problem, because if I set this settings:

ssl_bump peek all
ssl_bump splice all

everything opens fine

JonathanLee

@wndrew That should work also you're not bumping connections I have no issues with those websites.. did you create certificates ?

wndrew

@JonathanLee Yes, I have one

JonathanLee

How did you configure your squid ? Both transparent and ssl intercept? Loopback also?

wndrew

@JonathanLee Yes, transparent and ssl intercept + loopback

JonathanLee

@wndrew Those domains should work weird I never have issues with them

try this setting see if it helps?

tls_outgoing_options options=NO_SSLv3,NO_TLSv1,NO_TLSv1_1,NO_TICKET,SINGLE_DH_USE,SINGLE_ECDH_USE

wndrew

@JonathanLee it didn't help

tls_outgoing_options options=NO_SSLv3,NO_TLSv1,NO_TLSv1_1,NO_TICKET,SINGLE_DH_USE,SINGLE_ECDH_USE

What version of squid you are using?
Mine is

Squid Cache: Version 6.3
Service Name: squid

JonathanLee

@wndrew Squid 6.6 and Squid 5.8

JonathanLee

Wait…. Have you blocked DoH ?? And HTTP3 DoH over QUIC ? Your systems have to use pfSense as the DNS
