Dear All,
I have a problem with a Mikrotik router working as a PPTP client.
The topology is on the top.jpg.
Scenario:
I would like to reach the Telnet server behind the Mikrotik router (PPTP client) from the other PPTP Client (Win7).
The Mikrotik is connecting to the PPTP server with 3G USB stick.
Mikrotik Configuration:
-
I configured PPTP client. It is connected to the PPTP server.
-
I configured dst-nat to make the Telnet server reachable:
-
Chain:dst-nat
-
Dst: Address: 192.168.2.200
-
Protocol: tcp
-
Dst port: 2323
-
In. interface: pptp-out1
-
Action: dst-nat
-
To Addresses: 192.168.88.213
-
To Ports: 23
-
I configured src-nat for the return traffic from the telnet server:
-
Chain:src-nat
-
Src. Address: 192.168.88.213
-
Protocol: tcp
-
Action: masqurade
-
No other NAT rules are present.
-
Routes:
0.0.0.0, GW: 10.112.132.134 (3G), ppp-out1
10.112.132.134/32, GW: ppp-out1
192.168.2.1/32, GW pptp-out1
192.168.88.0/24, bridge-local -
I configured the default route on the Telnet Server to forward all traffic to Mikrotik LAN address (192.168.88.1).
The problem:
If I debug the telnet traffic on the Telnet server, I can see that TCP SYN packets are arrived properly and replies also sent to the Mikrotik, but it seems that the Mikrotik does not forward the traffic back to the tunnel.
Could you please help me how can I solve this problem.
Thank you in advance,
Zoltan
