patternihaandClaude Opus 5.5 9638715047 TUN inbound's autoSystemWfpBlockLeak: A CIDR in front of any value instead of "ipv4:" and "ipv6:"; Ports alone for TCP and UDP
A CIDR in front of any value limits it to its addresses, an IPv6 one in
brackets, e.g. "1.1.1.0/24:53", "[2001:db8::/32]:tcp/853" or
"[::/0]:all": "0.0.0.0/0:" and "[::/0]:" take the place of "ipv4:" and
"ipv6:". Like autoSystemRoutingTable, it takes CIDRs only, a single
address as "8.8.8.8/32", and no GeoIP.

"<port>" or "<low>-<high>" alone stands for TCP and UDP, so "dns" is
"53", "853" and "windnsclient" now.

The filters follow:
- One filter per layer permits what goes through the TUN, instead of one
  for each value.
- "all" and "misconfigtun" outweigh the local network that "allexceptlan"
  leaves open, so with it, "192.168.1.5/32:all" still blocks that address.
- The DNS Client service's mDNS and LLMNR stay allowed on the local network
  only, and only while no other value blocks them.
- The warning about blocked DNS servers only names those a value blocks.

patternihaandClaude Opus 5.5 f5cc086d6c TUN inbound: README.md says "ipv4:allexceptlan" includes "ipv4:dns" only
Add "dns" to block DNS over IPv6 as well.

patternihaandClaude Opus 5.5 6b45eadf45 TUN inbound: Recommend at least "dns" for autoSystemWfpBlockLeak in README.md, and shorten it
README.md now recommends at least "dns" to block DNS leaks, and lists the
values of autoSystemWfpBlockLeak more briefly, "dns" first. It also lists
FreeBSD among the systems, and mentions that on Linux, as on Android, the
TUN can be a file descriptor from xray.tun.fd (XRAY_TUN_FD).

patternihaandClaude Opus 5.5 c684201cd8 TUN inbound's autoSystemWfpBlockLeak: "ipv4:" or "ipv6:" in front of any value instead of "tcpv4" and the like
"ipv4:" or "ipv6:" in front of any value limits it to that IP version,
e.g. "ipv4:udp/53", "ipv6:all", "ipv4:dns" or "ipv6:misconfigtun".
"tcpv4", "udpv6", "icmpv4" and the like are gone. Values that only differ
in the IP version become one: "ipv4:udp/53" with "ipv6:udp/53" is
"udp/53".

"all" overrides "allexceptlan" per IP version, and "all" over one IP
version needs dns, as port 53 over one does.

patternihaandClaude Opus 5.5 2218fec173 TUN inbound's autoSystemWfpBlockLeak: Add "tcpv4", "tcpv6", "udpv4", "udpv6", "icmpv4" and "icmpv6"
"v4" or "v6" after the protocol limits a value to one IP version, ports
written the same way, e.g. "tcpv4/853" or "udpv6/10-20"; "icmpv4" is ICMP
and "icmpv6" is ICMPv6. Their filters go to the ALE layers of that version
only. "tcp", "udp" and "icmp" keep covering both.

Anything covering TCP or UDP port 53 in either IP version, like
"udpv4/53", still needs dns.

patternihaandClaude Opus 5.5 9ffa0f0552 TUN inbound's autoSystemWfpBlockLeak: Drop "/0"; Ports have to be 1-65535
"tcp/0" and "udp/0" no longer stand for all ports, which "tcp" and "udp"
already say: no syntactic sugar. Port 0 is rejected like any port outside
1-65535. Ranges keep being checked strictly: both ends within 1-65535, the
left one not greater than the right one.

patternihaandClaude Opus 5.5 2933b0c8d5 TUN inbound: Don't warn that loopback DNS servers are blocked
With autoSystemWfpBlockLeak, loopback now always stays allowed, so a DNS
server in dns like 127.0.0.1, a local resolver, stays reachable although
it lies in neither gateway nor autoSystemRoutingTable. Leave loopback
servers out of the warning that queries to them cannot go through the TUN
and are blocked, and say so in the README.

patternihaandClaude Opus 5.5 bb4cd4b6d3 TUN inbound's autoSystemWfpBlockLeak: Add "allexceptlan"
"allexceptlan" is "all" but for the local network: traffic to and from
private (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, fc00::/7), link-local
(169.254.0.0/16, fe80::/10), multicast (224.0.0.0/4, ff00::/8) and broadcast
(255.255.255.255) addresses stays allowed, so that printers, the router's
settings page, or casting to a TV keep working while nothing else leaves
outside the TUN.

It includes "dns": a resolver on the local network, like the router's,
would forward the queries outside the TUN, so DNS stays blocked there. The
LAN permit sits below the other values, like the permit through the TUN, so
they still apply on the local network, e.g. "tcp/445" blocks Windows file
sharing with it. The DNS Client service keeps mDNS and LLMNR, to the local
network's addresses only. "all" overrides it.

The addresses are matched with FWP_V4_ADDR_MASK and FWP_V6_ADDR_MASK
conditions on the remote address, which match when any of them does.

patternihaandClaude Opus 5.5 468f745fc2 TUN inbound's autoSystemWfpBlockLeak: Add "all", "tcp", "udp", "icmp" and port ranges; Always allow loopback, DHCP and IPv6 neighbor discovery
autoSystemWfpBlockLeak now also takes:

- "all": everything outside the TUN, IPv4 and IPv6, in both directions, so
  nothing but Xray leaves except through the TUN.
- "tcp", "udp": all ports of that protocol, also written "tcp/0", "udp/0".
- "tcp/<low>-<high>", "udp/<low>-<high>": a range of ports, matched with
  FWP_MATCH_RANGE, as two conditions on the same field would match when
  either does.
- "icmp": ICMP and ICMPv6, e.g. ping. It takes no port: in ICMP filters the
  local port holds the type, and "icmp/0" would read as the echo reply.

Values are normalized: "tcp/0" and "tcp/1-65535" become "tcp", and
"tcp/53-53" becomes "tcp/53".

Whatever is blocked, loopback, which cannot leave the system, and what
Windows itself needs on the local link now always stay allowed: DHCP, DHCPv6,
and IPv6 neighbor and multicast listener discovery. These used to be allowed
only along with "misconfigtun", so "udp" or "icmp" would otherwise have cut
DHCP or IPv6 neighbor discovery, and "tcp" any local proxy, Xray's own
inbounds included. Loopback being allowed means that with "dns", a local
resolver on 127.0.0.1:53 now works for other programs (its own queries to
port 53 or 853 outside the TUN stay blocked), and the DNS Client service
may use it.

"all" reuses the filters of "misconfigtun", which now also let everything
through the TUN, for both IP versions whatever the routes.

On other TUN options: keeping the system's DNS inside the TUN, with "all",
"dns", "windnsclient", or anything covering TCP or UDP port 53 ("udp",
"tcp/50-60", ...), needs dns, as Windows can no longer reach the DNS
servers of the other interfaces; the config is rejected otherwise. Like the
other values, the new ones need autoSystemRoutingTable. The filters do not
need autoOutboundsInterface, as Xray is allowed by its app ID; it still
keeps Xray's own connections out of the TUN's routes.

After the start network adapter with the name you chose in the config will be created in the system, and exist while Xray is running. A Wintun adapter that already has that name is reused.
With IPv6 disabled system-wide (the `DisabledComponents` registry value), the adapter has no IPv6, and the TUN starts with IPv4 only, unless `gateway`, `dns` or `autoSystemRoutingTable` has IPv6 entries, which then keep it from starting.
With IPv6 disabled system-wide (the `DisabledComponents` registry value), the adapter has no IPv6, and the TUN starts with IPv4 only, unless `gateway` or `autoSystemRoutingTable` has IPv6 entries, which then keep it from starting.
When `dns` is set, those servers are applied to the adapter. Windows is kept from registering the TUN's addresses in DNS, and its DNS cache is flushed when the TUN starts and stops. Xray's own lookups through the system's DNS servers, like those of the `localhost` DNS server with `autoOutboundsInterface`, skip them, unless another interface uses them as well, as they would lead back into the TUN.
