TITLE:=ISP-aware policy routing for mwan3 (nftables)
|
||
# 注意：这里故意不写 +mwan3 依赖。
|
||
# 官方 feed 的 mwan3 是 iptables 版（2.12.5），写 +mwan3 会错误地拉进它；
|
||
# Kwrt 源里 nft 版的包名是 mwan3-nft，与其他源命名不一致。
|
||
# nftables 版 mwan3 是硬性前提，由 install.sh 与 router-preflight 检查，
|
||
# 并在 description 里说明。

define Package/isp-split/description
|
||
Route traffic by the ISP that owns the destination address.
|
||
Builds mutually exclusive nftables sets from daily-updated
|
||
Chinese ISP CIDR data and wires them into mwan3-nft rules.
|
||
|
||
REQUIRES the nftables port of mwan3 (>= 3.6.0):
|
||
- Kwrt: apk add mwan3-nft (软件源里自带)
|
||
- 上游: 用 https://github.com/dl12345/mwan3 替换官方 feed 的
|
||
iptables 版 mwan3 (2.12.5)，或从 Release 下载
