I am trying to set up a pptp vpn so I can connect to my mikrotik boxes and get on the local side of them and check signals to my clients. I can connect to the mikrotiks, but cannot gain access on the inside.

The inside (ether2) does not have an IP, as there are many subnets being used behind it. I must connect with my vpn to the (ether1) side which is public and am trying to gain access to the ether2 side which is private.

Like I said, I can connect, but I cannot do anything after that. What am I doing wrong?

(Mikrotik box)

Ether1 - 65.87.**.** (this has the pptp server)
Ether2 - NO IP (this is the side I need to access)

pptp

local address - 192.168.100.1
remote address - 192.168.100.2

I tried with proxy arp on on the ether2 and still does not work.

Any help would be good.

Try using EoIP. Create one on each side, bridge the EoIP and ether you are connected to, then bridge the EoIP tunnel and the ether2 together on the router you are trying to get to.

I cannot do that because I am using a win2k3 machine to connect to the mikrotik boxes. EOIP is not supported in windows.

If you don't have any IP on ether2, and you aren't bridging to it, how would you expect it to work? Magic?

For proxy-arp to be of any help, you will need _some_ IP on that interface (preferably one in each of the networks you are trying to access, so the MT will know where to send the packets out).

I would suggest skipping proxy-arp, and just src-nating yourself instead.
