Subject: Enhance the "AllowedIPs"
Date: Mon, 15 Mar 2021 15:57:17 +0800	[thread overview]
Message-ID: <CAEK8JBC6Y7utcom7YCz5AX=bHPOkc6cOdMoMKTC=QhqBQwDp_A@mail.gmail.com> (raw)

Hi,

As we know, the AllowedIPs will set the route table. However, if we
want to set the CIDR, but except for some CIDR range, it's not so easy
and out of the box. For example, if I want to route my all traffic,
except the 192.168.0.0/16. I have to calculate the two CIDR
difference:

AllowedIPs =
0.0.0.0/1 + 128.0.0.0/1 - 192.168.0.0/16
=
0.0.0.0/5,8.0.0.0/7,11.0.0.0/8,12.0.0.0/6,16.0.0.0/4,32.0.0.0/3,64.0.0.0/2,128.0.0.0/2,192.0.0.0/9,192.128.0.0/11,192.160.0.0/13,192.169.0.0/16,192.170.0.0/15,192.172.0.0/14,192.176.0.0/12,192.192.0.0/10,193.0.0.0/8,194.0.0.0/7,196.0.0.0/6,200.0.0.0/5,208.0.0.0/4,224.0.0.0/3,10.99.0.0/24

Is it possible to be built in Wireguard in the future? I think it's very useful.

Thanks.
