can't ping pptp or l2tp client from LAN

RouterOS General
1

Hello,
scenario as follow:

Subnet 192.168.10.x
router 192.168.10.1
pptp client remote address 192.168.10.30 to 192.168.10.36
pptp client local address 192.168.10.2
local lan 192.168.10.100-192.168.10.150

recently a weird problem showed up on Mikrotik , that i can’t ping pptp or l2tp client from Lan ,
they are pingable from the router itself but not from lan, knowing that old created pptp user is pingable normally.

proxy-arp is enabled on bridge-local,
when i try to ping the pptp ip address from lan i get request timed out when the clent is connected, and destination host unreachable when the pptp client is not connected.

i changed the proxy-arp on bridge to enabled only,
when i ping the pptp client ip address i have having destination host unavailable always, when the pptp is connected or not connected.

from Mikrotik itself all pings are fine.

i created a new bridge with a diffrent subnet:
and i assigned the new pptp client local and remote address to that new bridge subnet 192.168.30.X
and i assigned a port to that bridge as well, and connected a pc to it ,
all pings are back to normal .

and i tried to edit a name of one of the old working pptp when i did that the issue showed up on that user as well.
i restored the router to an era that everything was working good, with no luck
tried to clear arp from ip-arp with no success as well
i assigned the pptp profile to bridge-local
i deleted the brigde local than recreated it, and it didn’t worked

kindly advise

thank you

i still have that issue even from mikrotiks
can’t ping remote mikrotik from local lan
remote mikrotik connected via pptp or l2tp to local mikrotik
has a remote address of the local bridge
help

I also had this problem when I was trying to set up PPTP server. I ended up with creating a different subnet for remote connections.

the remote mikrotik was working okay with pptp client 1.
i created on the same miktotik pptp client 2 .
disabled the pptp client 1 interface and connected through pptp client 2 interface
when i did this i can’t ping anymore the remote mikrotik from the local lan.

i restored the connection through:
i did telnet from the local mikrotik to the remote mikrotik, (tools telnet)
then interfaces enable pptp client 1
everything back to normal

i am going crasy… any clue?
i did everything with firewall, nat , bridge

tried diffrent subnet with no luck,
what you mean by diffrent subnet.
i added another subnet to bridge local and tried and didn’t worked
noting that in all cases i can reach the local address | the ip that should route me to the pptp ip address

problem solved it was a route issue for both way

Two things are required:

  1. proxy-arp on the local interface that your LAN is connected to.
  2. a masquerade rule between the local LAN subnet and the single remote IP in the same subnet.
