Hello everyone,

I have a weird thing with my OpenVPN server on my router BE800.

I have the following home network at home 

I have a few VMs running on an KVM servers, and :
- I can reach the VMs (192.168.10.170 and 171) and everything else when i'm connected on the LAN (ping and apps)

- I can't reach VMs (170 and 171) when on the OpenVPN server on the router, everything else works.

- I can reach them with an OpenVPN server deployed on the LAN (VMs, devices, everythink works)

All the VMs are on the same Lan as the other devices, everything is using DHCP, no firewall.

The "Router" OpenVPN is working perfectly for everything directly connected on the LAN, but not for virtualised ressources.

I've deployed a similar OpenVPN instance on a Raspberry Pi connected directly on the LAN : and with this one -> Everything is working perfectly.

Both were tested on TUN mode. (TAP not supported on my mobile phone)
I've tried to mimic all the settings between the router and the "Raspberry test".

Would someone had an idea about the why ?

Thank you
