Re: [ wireguard-dev ] About configuring allowedip
ok thanks, what is confusing me it that allowed ip is for : - authorized source packet - routing outgoing packet and we can set allowedips with a lot of ip / netmask Regards, Nicolas 2017-02-24 14:10 GMT+01:00 Dan Lüdtke: > Nicolas, > > I draw your network including the allowed_ips restrictions. > > > ping peer3 --peer1--->peer2 : not ok . > > This can not work!

Re: [ wireguard-dev ] About configuring allowedip
Nicolas, I draw your network including the allowed_ips restrictions. > ping peer3 --peer1--->peer2 : not ok . This can not work! Peer 2 does not accept the source address from Peer 3. Please review your allowed_ips settings. Draw the things on paper, make PostIt notes representing the packets including their destination address and source address. Draw a little "firewall" on the tunnels (whitelist is allowed_ips, all the rest gets dropped!) and see if the PostIt can make it through with it's source address. Yes, this sounds like child play, but it works. I have taught complex firewalling and VPN setups to lawyers and law makers this way. It helps understanding, if a simple diagram does not cut it. Allowed IPs is probably the most complex thing WireGuard has to offer from a user perspective. Rename it to Allowed Source Addrresses in your head it becomes clearer.

It should work with a single interface for both peers, but you need to activate forwarding in the kernel: # sysctl net.ipv6.conf.default.forwarding=1 > so my question is : > - two interface ? > - specifiq magic allowedip ? > ( allowed ip is confusing for, it is using for routing and for evicting > paquet ? ) > > Regards, > Nicolas > ___ > WireGuard mailing list > WireGuard@lists.zx2c4.com > https://lists.zx2c4.com/mailman/listinfo/wireguard signature.asc Description: PGP signature ___ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard
[ wireguard-dev ] About configuring allowedip
Hello, i'm trying to do this with wireguard, withtout success : peer1 ---> peer2 : config ok , works peer3 ---> peer1 : config ok , works peer3 --->peer1 ---> peer2 : not ok . I suspect allowed-ip configuration, but all my tests does not works. perhaps I must create two wireguard interface on peer 1 and do forwarding/routing ? i'm using ipv6 as internal ip. so my question is : - two interface ? - specifiq magic allowedip ? ( allowed ip is confusing for, it is using for routing and for evicting paquet ? ) Regards, Nicolas ___ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard
