Hello, you are my only hope. There is no information about this in the net.
I have PPTP server on my RB2011UiAS and have windows remote PC. I want to play games from my lan to that remote PC. But, as I know, PPTP drops UDP broadcast. Is there ANY WAY to fix this on mikrotik side? Don’t want to use programs on PC…
Thanks.
Thanks for reply. I have already turned on proxy-arp on ALL interfaces… But no luck… Am I missing something?
The PPTP server should assign client IP addresses from the same range as the LAN.
(You could probably specify the client address pool to be the same pool that DHCP server is using)
Whatever your router’s LAN IP address is (e.g. 192.168.88.1) should be set as the “local address” on the profile you’re using for the PPtP clients.
Then, the LAN interface should have arp=proxy-arp - you don’t need that set on any other interface (but it doesn’t really hurt anything either if you leave it on)
If the clients’ IPs are from a different range than your LAN uses, then any broadcast traffic on the LAN will NOT be forwarded to the remote PCs. In this scenario, anything requiring broadcast-based discovery (search for LAN games, for instance) will not work. That’s likely to be your issue.
Nope, I am using same pool. DHCP gives 192.168.1.40 to PPTP client and my default gateway is 192.168.1.1. OpenVPN TAP works perfectly on anything. But on PPTP, SSTP, L2TP it’s not working. PROXY-ARP-s are tured on… I am going crazy 
On OpenVPN TAP everything works PERFECT! Games, VNC server etc… WITHOUT PROBLEM. How to make PPTP or L2TP or SSTP work like this?
If it is impossible, say that it is impossible. I’m tiered searching in google and Mikrotik forums. There is no concrete solution in the net for Mikrotik based VPN server. I see same bull … everywhere.
Yep, it’s impossible. It should be theoretically possible with L2TP, but not with Windows client (it does not implement BCP). The closest thing you can get is proxy-arp, but it’s not going to help you with broadcasts, I’m afraid.
Okay, thank you very much for first helpful answer for last 3 days!
