…k for routing rationale: Using an Endpoint that is part of a network in AllowedIPs (e.g. Endpoint=162.12.13.1 and AllowedIPs=162.12.13.0/24) will cause a looping route when enabling a wireguard connection, because of the routes created by AllowedIPs values. This could be solved using the more advanced fwmark-based routing (that you describe as "Improved Rule-based Routing"), but it only takes effect when AllowedIPs contains 0.0.0.0/0. This patch allow users to override that behaviour in a simply way. This patch does not fix the root problem, which could be addressed in one of the following ways: - Finding Endpoints that are part of networks present in AllowedIPs, and only enabling fwmark routing for them - Always use fwmark routing, even if we don't need it I do not have enough knowledge to choose which option to implement (although I prefer WireGuard#2 because of implementation simplicity). I would like to submit another patch for this, but I will need guidance on what option to choose.
