我居住的地方互联网审查相当严格，因此我希望能够在家庭服务器上运行代理，通过 openvpn 隧道传输所有互联网流量，这样我就可以自由访问被屏蔽的网站。我的家庭服务器运行 nginx，我的最终目标是拥有一个子目录，我可以从中访问特定的被屏蔽网站。以前有人这样做过吗？
我已尝试过：
我尝试设置 nginx 正向代理，但我想要访问的被阻止网站使用 cloudflare，并且我一直收到错误503& 1001。经过一番研究，我发现这是一个基于 SSL 的错误，而 nginx 没有能力做到这一点，我应该转向squid。
我的squid配置如下：
acl localnet src 0.0.0.1-0.255.255.255 # RFC 1122 "this" network (LAN)
acl localnet src 10.0.0.0/8 # RFC 1918 local private network (LAN)
acl localnet src 100.64.0.0/10 # RFC 6598 shared address space (CGN)
acl localnet src 169.254.0.0/16 # RFC 3927 link-local (directly plugged) machines
acl localnet src 172.16.0.0/12 # RFC 1918 local private network (LAN)
acl localnet src 192.168.0.0/16 # RFC 1918 local private network (LAN)
acl localnet src fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines

# Recommended minimum Access Permission configuration:
#
# Deny requests to certain unsafe ports
http_access deny !Safe_ports
# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports
# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager
# This default configuration only allows localhost requests because a more
# permissive Squid installation could introduce new attack vectors into the
# network by proxying external TCP connections to unprotected services.
http_access allow localhost
http_access allow localnet
# The two deny rules below are unnecessary in this default configuration
# because they are followed by a "deny all" rule. However, they may become
# critically important when you start allowing external requests below them.
# Protect web applications running on the same server as Squid. They often
# assume that only local users can access them at "localhost" ports.
http_access deny to_localhost
# Protect cloud servers that provide local users with sensitive info about
# their server via certain well-known link-local (a.k.a. APIPA) addresses.
http_access deny to_linklocal
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
# For example, to allow access from your local networks, you may uncomment the
# following rule (and/or add rules that match your definition of "local"):
# http_access allow localnet
# And finally deny all other access to this proxy
http_access deny all
# Squid normally listens to port 3128
http_port 3128
tcp_outgoing_address 10.24.0.5 localnet
# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/cache/squid 100 16 256
# Leave coredumps in the first cache dir
coredump_dir /var/cache/squid
#
# Add any of your own refresh_pattern entries above these.
#
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320
然而，这不起作用，因为当我尝试通过代理访问该站点时仍然可以看到我的 ISP 的阻止消息。
我该如何实现我的目标？还有其他软件吗？TIA。
PS 我也研究过 Linux 命名空间，但它们不适合我的用例。
