Virtual private networks / strange problem with wireguard, no connection to some ips in lan, but most work
« on: May 21, 2024, 02:12:38 pm »
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?
