Hi,

I have server with MT 3.18 in DataCenter with 99.88.99.0/24 subnet.
Gateway 99.88.99.1. Server ip 99.88.99.2.
I want connect to this server via PPTP-client from my MT-router and get ip 99.88.99.3:
i enable pptp server, add user with local-ip 99.88.99.1 remote-ip 99.88.99.3.
pptp-client connected but internet not work. i ping 99.88.99.1 after connect normally but can't ping any host in internet.

Where I have problem ?

set arp=proxy-arp on ethernet interface

not working

proxy-arp should work if you set everything correcty.
Look at example in the manual and check if you have everything set up:
