Ok here is what I have: I have an existing LAB network(network1) on a 192.168.1.0/24 network. there is a router that NATs traffic from that network to our company network(network2) which is 192.168.0.0/24 network. the LAN IP of the 1st router is 192.168.1.1 and its WAN is 192.168.0.25
so now I have my MikroTik that I want to use as a VPN Server into my lab network from the outside world. so i set up ether0 as a public IP and connected it. then I set up ether1 on the Mikrotik as 192.168.1.2, set up a PPTP-Server on the mikrotik with an address pool and secrets and enabled Proxy Arp on the ether 1 Interface.
I could Log into the VPN no problem and axxess machines where I need to.. HOWEVER I found that machiens started disappearing off of our company network in the 192.168.0.0/24 network.. pulling ARP tables it was the MAC of my ether1 showing up as owning all the IP’s…
what is the CORRECT way to set this up so I dont kill the network.. im asuming what happened is the ARP traffic is somehow getting routed through the first router.. ive never had this kind of issue ocur before using MikroTik so im thinking there is a setting I have wrong..
without Proxy-ARP enabled then the PPTP server doesnt work correctly at all…
any help is appreciated
