[Resolved]PPTP vpn configuration[Resolved]

Mon Jul 02, 2007 6:35 pm

Hi all
I want to setup a vpn connexion from a remote client (Microsoft pptp client) and a Mikrotik pptp server.
The goal is to have an acces (from the remote client) to a LocalWebServer in the LAN behind the MT Router.
The Mikrotik router is nated on a ADSL router (on the port 1723):

Server configuration on MT Router:
ppp secret> add name=test password=test
local-address=10.23.53.60 remote-address=10.23.53.60
interface pptp-server> add name=pptp-vpn user=test
interface pptp-server server> set enabled=yes
The VPN connexion is estabilished correctely, but i can't acces the LocalWebServer.
Where is the problem??

Usually it's because proxy arp is not enabled on the LAN interface of the MT box.

Hi
In fact i have 5 Ethernet port on my MT Router and they are all in the same bridge (ip of the bridg is10.23.53.254), the LocalWebServer is pluged in the Ethernet4 and the ADSL Router is pluged in an other Ethernet port.
I used the proxy-arp on the Ethernet4
interface ethetnet> set ethernet4 arp=proxy-arp
but the problem is always there.

is it the good configuration??
what it the problem plz.

From my experiece i can't build pptp-server works on bridged interface, if i use non-bridged interface it works just fine. I dont know why :D Maybe my configuration not perfect enough doh.

When the vpn is estabilished, the remote client got the adress 10.23.53.61 and he can ping the Mikrotik router (10.23.53.254) but it can ping nothing else on the LAN (i don't understand this behaviour)
