strange problem with wireguard, no connection to some ips in lan, but most work

[Benni-chan]

Hi,

I have a strange problem with my wireguard installation on OPNSense (latest version).
I can connect to Wireguard, get Handshake and can connect to most IPs in the subnet, but not all.

I can even reproduce this with the diagnostic ping inside OPNsense. I can ping the ip, but if I set the source IP to the wireguard subnet, to ping fails.
another device works, even from the wireguard subnet.

I guess, there is some error in the routing table, but I don't really know where to look.

I've attached some screenshots with the ping and the wireguard instance and peer config.
I have a firewall rule on the wireguard interface to allow all traffic from and to everywhere.

any idea?

Hi,

I think I have the same problem.
Connection works fine, but for example, I can ping 192.168.1.2, but not 192.168.1.3.
Also internet is not working when connected to vpn.

Everything was working fine, until I tried to delete old vpn instance and create new one. With new one things went downhill.

If anyone has any idea before I delete all and start all over again, please let us know   

Edit: I forgot to put in tunnel address. Now it works just fine.


Best regards
