I am trying to connect a CCR1036-8G-2S+ to an ubuntu VM over wireguard. The handshake and sending from the CCR to the VM works, but sending from the VM to the CCR seems to get lost somewhere in the receive path of the CCR.
Interfaces:
- ether4: Adminstrative access so I don't need to use the serial port.
- ether8: Connected to the internet.
- wg-test: Wireguard interface.
tcpdump on the VM can see traffic in both directions and the exactly same config works against another VM so that shouldn't be the issue. Running /tool/sniffer on wg-test of CCR sees the packets CCR->VM but it doesn't see the packets CCR->VM. The rx counter also doesn't seem to increase based on the actual packets, only very infrequently (maybe handshakes?). Running /tool/sniffer on ether8 of CCR sees the wireguard packets in both directions so I think the issue is within the receive path of the CCR.
