pptp-out on RB2011UiAS-2HnD-IN

Hi guys,

I’m a bit confused with pptp VPN client on RB2011UiAS-2HnD-IN model. Just a short description - I have Linux-based VPN gateway (pptpd). Two MT’s - RB750Gr3 and RB951G-2HnD works fine with the same pptp client settings - the pptp out interface is established, I see both connections on Linux:

ppp0 Link encap:Point-to-Point Protocol
inet addr:192.168.0.123 P-t-P:192.168.0.235 Mask:255.255.255.255

ppp1 Link encap:Point-to-Point Protocol
inet addr:192.168.0.123 P-t-P:192.168.0.234 Mask:255.255.255.255

collisions:0 txqueuelen:3
RX bytes:2934346 (2.7 MiB) TX bytes:302828 (295.7 KiB)

I’m able to ping both 192.168.0.234 and 192.168.0.235 IP’s from Linux - everything is fine till this part.

Now I create the same pptp-out connections on RB2011UiAS-2HnD-IN, the link is established, I see it on Linux as well:

ppp0 Link encap:Point-to-Point Protocol
inet addr:192.168.0.123 P-t-P:192.168.0.237 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1446 Metric:1
RX packets:9 errors:0 dropped:0 overruns:0 frame:0
TX packets:26 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:330 (330.0 b) TX bytes:1734 (1.6 KiB)

BUT! I can’t pint 192.168.0.237 from Linux.
Also 192.168.0.123 is also not available from RB2011UiAS-2HnD-IN

RB2011UiAS-2HnD-IN ‘first-run’ was configured as Home-AP if this is important.

Could you please help me with this issue?

Thanks.

RouterOS is same on all devices. Maybe the problem is elsewhere, PPTP is not exactly firewall-friendly protocol, so it’s possible that GRE packets are blocked somewhere on the way.
