Remote PPTP client cannot ping computers in lan

Ver. 6.11 on RB951G-2HnD.
I have PPTP server on this router and can connect it from outside. Connection is stable, I receive IP 192.168.88.2 (assigned for pptp user “mike”) and can manage router (192.168.88.1). Web browser on my remote computer works stable via my pptp connection.

But I can’t ping (and access at all) any local computers. For example, local qnap have 192.168.88.10 and I can’t ping it :frowning:

What can be source of the problem?

On this router:
NAT: masquerade / srcnat. Local computers have internet. Ok.
Input: dst port 1723. I can connect from outside as pptp client. Ok.
Output chain: accept all. Probably Ok.

Forward chain? NAT? May be routing? How to check where is the problem?

On the bridge of your router switch arp to ‘proxy-arp’

On bridge-local?
Now arp is set to “enabled”.

Thank you. I have start to read manual about this option…

As I see, best way is to use separate ip network for VPN clients and use routes instead of use proxy-arp, isn’t it?

I agree, but there are some limitations to this approach.
