Keys in string format or integer format (key=value)

• tunIPv4Address: TUN IPv4 adrress, 172.19.0.1/30 by default
• tunIPv4DNSAddress: TUN IPv4 DNS adrress (an empty value means "not set"), 172.19.0.2 by default
• tunIPv6Address: TUN IPv6 address, fdfe:dcba:9876::1/126 by default
• tunIPv6DNSAddress: TUN IPv6 DNS address, "not set" by default
• fakeDNSIPv4Pool: fake DNS IPv4 address pool, 198.18.0.0/15 by default
• fakeDNSIPv4PoolSize: fake DNS IPv4 address pool size, 65535 by default
• fakeDNSIPv6Pool: fake DNS IPv6 address pool, fc00::/18 by default
• fakeDNSIPv6PoolSize: fake DNS IPv4 address pool size, 65535 by default

Keys in string array format or integer array format (key=value, key=value1,value2)

• tunIPv4RouteAddress: TUN IPv4 route address, 0.0.0.0/0 (see this for the default address when "bypass private address" is enabled, it is the complement of private IPv4 addresses) by default. Route 0.0.0.0/8 to make LineageOS (and other systems) "allow clients to use VPNs" work.
• tunIPv6RouteAddress: TUN IPv6 route address, ::/0(2000::/3 when "bypass private address" is enabled) by default
• remoteDNSDomainList: the domain set resolved by remote DNS, generated by the software based on routing rules by default
• directDNSDomainList: the domain set resolved by direct DNS, generated by the software based on routing rules by default

Keys in boolean format (key=true, key=false)

• shadowquic: Show ShadowQUIC settings (compile the plugin yourself). This may get changed or removed at any time.
• singuot: Show sing-uot settings. This may get changed or removed at any time.
• singmux: Show sing-mux settings. This may get changed or removed at any time.
• lookupAsExchange: Handle A/AAAA queries in the same approach as non-A/AAAA queries. This will disable internal DNS cache mechanism as well. This is a temporarily option.
• discardIPv6BasedOnNetwork: Determine whether to discard IPv6 packets or not at the network layer based on the present of non-local link IPv6 addresses (fe80::/10) on the outgoing network interface. The discarding behavior happens before TCP handshake. This is a temporarily option.
• useInternalObfsLocal: Always use internal simple-obfs implementation even if the standalone plugin has been installed.
• useInternalV2RayPlugin: Always use internal v2ray-plugin implementation even if the standalone plugin has been installed.
• disableShadowsocksPluginConfigActivity: When editing Shadowsocks plugin options, do not launch ConfigActivity of the plugin and use a text input box.
