F100-S-G2 L2TP LAC問題

問題描述：
F100-S-G2做為網關或旁掛核心交換機（兩個模式都測試過），防火牆固件版本為官方最新版，配置l2tp mode lac 對接友商設備，某捷，某為，隧道可以成功建立，但是沒有會話，virtual-ppp 頻繁up down
配置應該沒問題的，用戶名密碼，隧道密碼，多次確認了沒錯，相同網絡環境下使用msr800路由器配置lac模式能正常通信
請問各位大佬，是什麼原因導致的呀，安全策略放行了呀，不然隧道也建立不起來呀

最佳答案
F100-S-G2防火牆L2TP LAC模式隧道建立成功但無會話、Virtual-PPP頻繁UP/DOWN的可能原因如下：
**1. PPP認證方式不匹配**
- 雖然用戶名密碼正確，但需確認兩端**PPP認證方式（如PAP/CHAP）是否完全一致**。若LAC端與LNS端認證方式衝突（如一端強製CHAP，另一端僅支持PAP），會導致PPP協商失敗，引發Virtual-PPP接口震蕩。
**2. MTU/MSS參數衝突**
- L2TP封裝會增加報文頭部，若未調整MTU/MSS值，可能導致分片或丟包。檢查並調整：
interface Virtual-TemplateX
mtu 1400 # 建議降低MTU（如1400）
tcp mss 1200
```
**3. NAT穿越未啟用**
- 若LAC或LNS位於NAT設備後，需在防火牆開啟NAT穿越支持：
l2tp-group X
tunnel name lac-name
start l2tp ip <LNS_IP> # 確保配置正確LNS地址
tunnel authentication # 隧道驗證狀態需與LNS端一致
tunnel password cipher XXXX # 密鑰必須與LNS完全一致（包括空格）
l2tp nat enable # 關鍵！啟用NAT穿越
```
**4. 組號與隧道名稱對應關係**
- 若LNS端組號非默認值（如組號為2），需在LAC端明確指定隧道名稱與LNS端**完全一致**（包括大小寫）。
**5. 設備兼容性問題**
- 不同廠商L2TP實現可能存在差異，需檢查：
- **LNS端是否要求強製IPSEC綁定**（如友商設備默認策略），導致純L2TP無IPSEC時被拒絕。
- **H3C防火牆默認組號為1**，若LNS端組號非1，需在LAC端顯式配置`group-id`參數。
**6. 安全策略遺漏**
- 安全策略需放行**UDP 1701（L2TP）和IP協議47（GRE）**，而非僅L2TP隧道建立階段流量。檢查是否存在如下策略：
security-policy ip
rule name permit_l2tp
action pass
source-zone untrust
destination-zone local
service udp-1701 # L2TP控製報文
rule name permit_gre
action pass
source-zone untrust
destination-zone local
service gre # GRE封裝數據報文
```
**7. 日誌與調試建議**
- 執行以下命令獲取詳細故障信息：
debugging ppp all # 查看PPP協商過程
debugging l2tp all # 查看L2TP隧道細節
display l2tp session # 檢查會話狀態
display interface Virtual-PPPX # 觀察接口震蕩原因
```
**8. 固件潛在問題**
- 盡管使用最新版本，仍可能存在L2TP兼容性缺陷。參考案例庫或聯係H3C技術支持，確認當前版本是否存在已知Bug（如NAT穿越實現異常）。
**總結**：優先檢查**PPP認證方式、MTU/NAT穿越配置、安全策略完整性**，結合調試日誌定位具體協商失敗階段。若仍無法解決，建議提供`debugging ppp all`及`display l2tp session verbose`輸出，以便進一步分析。

再對比看下，如果不行的話，debug l2tp all看下

大佬debug了，麻煩看下，謝謝

看一下日誌，然後開啟debug抓包看一下，debug security-policy packet 也給打開
