From: Tom Yan <tom.ty89@gmail.com> To: wireguard@lists.zx2c4.com Cc: Tom Yan <tom.ty89@gmail.com> Subject: [PATCH] wg-quick: avoid traffics from momentarily leaking into the tunnel Date: Fri, 17 Jun 2022 19:34:19 +0800 [thread overview] Message-ID: <20220617113419.17329-1-tom.ty89@gmail.com> (raw) The wireguard route table ip rule should stay as a NOP until the `suppress_prefixlength 0 table main` rule is in effect. Therefore, add the wireguard default route to its route table after the latter rule is added.
