The problem of enabling VPN on mobile phones through WinDivert #340

Closed DynixDynix closed 1 year ago

Why not let WinDivert be written based on NDIS LWF and based on WFP I had a project before that could not intercept ICS data under any circumstances (when Windows was doing soft routing NAT). Will it be implemented in a future version?

I found normal data packets using Wireshark, but I couldn't see them in WinDivert. It was the first time I saw this situation, and of course, he was very good at handling local data packets

Some protocols are layer 2, so would not be visible to WinDivert.

There is an experimental version of WinDivert with Layer 2 support here: https://github.com/basil00/Divert/tree/eth_layer However, this version has an issue where networking will pause each time a filter is added/removed, so this version has not been released. I understand that the same issue would exist for NDIS LWF drivers.

Can the current version be injected at the forward layer？My current computer is a soft router, and after opening the ICS service, my phone shares the network through the computer. After I opened the WINDIVERT_LAYER_NETWORK_FORWARD handle,I can see more data packets, I can see that the connected device requests the target server, but redirecting the IP to its own proxy server seems to have no effect, I don't know where I did something wrong,If you could provide some ideas,I would greatly appreciate it!
