广州电信进小黑屋

宽带平时是直播+挂 BT 。最近 30 天，PeerBanHelper 统计 BT 大概传了 1.2T 。Windows 统计 OBS 传了 635G ，看了下后台播了 111.5 小时。减掉这些算了一下下载，没算手机大概下载了 2.3T 这样

9 号晚上突然发现 IPv6 掉了，尝试重新拨号还是拿不到。路由器自身还能拿到 240e:3b0::的/64 ，但是拿不到 240e:3b4::的/60 PD 了

ifstatus wan_6

        "ipv6-address": [
                {
                        "address": "240e:3b0:4c0:xxxx:xxxx:xxxx:xxxx:xxxx",
                        "mask": 64,
                        "preferred": 172203,
                        "valid": 258603
                }
        ],
        "ipv6-prefix": [

        ],
        "ipv6-prefix-assignment": [

        ],

路由拿到的 IPv6 还能通

curl -6 ip.sb
240e:3b0:4c0:xxxx:xxxx:xxxx:xxxx:xxxx

因为本来就没 IPv4 公网，IPv4 似乎没什么变化

ifstatus wan

        "ipv4-address": [
                {
                        "address": "100.64.174.79",
                        "mask": 32,
                        "ptpaddress": "100.64.0.1"
                }
        ],

mtu 似乎还是 1492

ip a

11: pppoe-wan: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1492 qdisc fq_codel state UNKNOWN group default qlen 3

用 NatTypeTester 测 Mapping & Filtering behavior 都是 EndpointIndependent ，发现 natmap 还能打洞出去，就用 librespeed/speedtest-rust 搭了一个测速，然后用联通流量测

librespeed-cli --local-json
Using local JSON server list: /mnt/d/apps/config.json
Selecting the fastest server based on ping
Selected server: Rust Backend [2xx.xxx.xx.xx5]
You're testing from: 1xx.xx.xx.xx4 - China Unicom Guangzhou network, China
Ping: 38.18 ms  Jitter: 5.44 ms
Download rate: 23.13 Mbps
Upload rate: 13.96 Mbps

看来流量上传有点慢，但是下载还是能测出宽带的上传的。我又去下了个 BT ，下载能跑到满速，没什么问题

试了一下 traceroute ，好像没什么问题
