ARP Between VPN

[essides]

Hello,

I have some VPN clients ( PPTP , L2TP ) and I want they can find each other as in a LAN

How can I do it ?

Thanks you.

LAN access is over bridge. To have the VPN’s on the VPN server connected via bridge, I assume you just set this default bridge in the “PPP profile”, and use that profile in all PPTP and L2TP VPN .

Yes, both VPN services use same profile with bridge option selected.

Selected bridge have arp-proxy selected.

Does it work with this config?

Final clients are using Windows OS, so I cant configure BCP protocol.

Thanks you.

How did you get it?

Cause my vpn clients can’t see physical address each other

If you use a conventional IP / layer 3 VPN, you have no access to the MAC / layer 2 information at the other end.

Proxy-arp allows a router to provide its own MAC address to allow communication between devices using the same subnet IP addresses but attached to differing physical networks, e.g. a local LAN and a VPN client. If you really need layer2 access you will have to use EoIP, possibly OpenVPN tunnel mode although I haven’t tried the latter.
