How to carry the MAC address of the device on the other party's LAN? #1112

Closed qq1793228602 closed 1 year ago

qq1793228602 commented 1 year ago

I am now able to ping the IP of devices on the other party's LAN, and my local tool can also connect. At that time, my tool had a function of scanning devices and using the ARP protocol, which required the MAC address of the link layer. However, n2n is forwarded through a route and seems to not carry it. However, my tool cannot directly search for devices, resulting in the need to manually enter the IP

This sounds like you need to use bridging and not routing - there was support added for bringing recently

(Unfortunately, the documentation in doc/Bridging.md is currently incomplete but you might find some hints in the thread that added this feature #1044)

Does the current version support it? I saw a supported version in the Q&A section https://github.com/emanuele-f/n2n/tree/switched_traffic2 But this is v2.4

Yes, the current dev branch contains support for bridging - the fork you found is quite old and is not relevant to the support that was merged into dev.
