Hello,

Been a while since I posted, had to create a new login. Anyway, I have a problem with inbound PPTP not connecting to local LAN IP's. the problem started after implementing PCC DUAL WAN load balancing. When I disable WAN 2 (the new WAN) the problem goes away. Therefore, I think I need Pre and post routing rules to handle my PPTP connections.

I have Three Ethernet ports. WAN1, WAN2, and home. My home ip range is 10.0.5.0/24. My pptp come in on WAN1 and use 10.0.55.0/24 pool. Any suggestions on what to change we be much appreciated as this one has me scratching my head. Yes, I have proxy arp on home.

Hi knotpc, i've exactly the same problem as you. I've tested pptp connection in another routerboard with just 1 wan connected (no PCC) and it works great (even if i don't set proxy-arp over lan interface).
When using PCC pptp server can't reach local network (you can only ping the gateway > checked with tracert).

I've also another problem!! I though i could use Microsoft RRAS and dst-nat tcp 1723 to the RRAS server, for using pptp because i can't work without PCC load balance, and here comes the new little surprise!!!
I can connect and use pptp connection through mikrotik pointing to the inner RRAS server but the connection is automatically dropped 3 minutes after it connects!!! NICE!!! I was searching in forums and this problem is associated with routerOS version (3.x or later).

So... We can't reach inner network when load balance is active > Mikrotik PPTP server.
And we get disconnected when forwarding pptp connection to some other third party PPTP Server.

=( Hope someone could help us.

Regards

Forgot to post the solution to this.

At the top of the Mangle simple put a rule like:

add chain=prerouting dst-address-list=LocalNet src-address-list=LocalNet

In my case I created a LocalNet Address-List that has the PPTP and the Local LAN IP Ranges.

This fixed the problem.
