define Package/sniproxy/description
 Transparent TLS and HTTP layer 4 proxy with SNI support
 Proxies incoming HTTP and TLS connections based on the hostname contained in
 the initial request of the TCP session. This enables HTTPS name-based virtual
 hosting to separate backend servers without installing the private key on the
 proxy machine.

It compiles on Openwrt 22.03.2, but when I install the generated package on my Openwrt router (DIR 853 A1, MT7621), it failed with "Segmentation Fault". The configuration that I used was tested on my PC.
