Hi,
I have on my mikrotik create a pptp server like describe on http://wiki.mikrotik.com/wiki/Manual:Interface/PPTP I can connect with the vpn client. Also I can ping the mikrotik router. But I can’t ping any host on the local network. I have enabled proxy-arp on the local interface as described in the manual.
Has anyone any idea what I’m donning wrong. I’m using version 5.21 on RB450G
I have a network 172.26.12.0/24 where the mikrotik is the default gateway (172.26.12.117).
The PPTP client get the following ipconfig:
ip-address: 172.26.12.250
subnet: 255.255.255.255
default-gateway: 172.26.12.250
From this client I can ping the mikrotik (172.26.12.117) but nothing else in the 172.26.12.0/24 network. And from the network I can’t ping the pptp client 172.26.12.250.
It looks like I miss some routing…
But I don’t see it.
[admin@MikroTik] /ip route> print

C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme,
B - blackhole, U - unreachable, P - prohibit

3 ADC 192.168.178.0/24 192.168.178.201 ether1-gateway 0

I hope this will give a little bit more information.
Try making a dedicated PPP interface for this user and then check your forwarding rules to make sure that you are actually allowing the traffic - the PPP interface needs to be able to open new connections to that local subnet range.
Seems you have proxy-arp selected already which is the usual suspect…
I have add the interface described as above. After this it works. But the strange thing, when I removed this interface it still keeps on working. To be sure I have rebooted and after that is still works.
I don’t know why. I don’t see what is changed. Probably I have done something wrong? I don’t know what but it works now. Thanks everybody for the help.
I’m really frustrated, i can’t get it work, the pptp client connects but can’t gain access to network hosts at all, i’m just able to ping the gateway.
After follow the wiki http://wiki.mikrotik.com/wiki/Manual:Interface/PPTP,
enabling “proxy-arp” on the BRIDGE interface that points to the network, still can’t get a tracert “LOCAL_IP”, it just get to the gateway.
Here is my config in routerOS v5.12 attached, hope someone could please help me =( iproute.txt (950 Bytes) ipfirewallmangle.txt (2.42 KB) iface_pptp-server.txt (281 Bytes)
i’ve create a dedicated PPTP-SERVER for the user but without luck
INFO UPDATE:
Mikrotik routerOS v5.22
The problem with routerOS PPTP Server:
It appears when using more than 1 WAN interface and PCC load balance (as my config). If i disable 1 wan pptp works ok (but i can’t work here with just 1 wan).
Another big problem:
When dst-nat tcp 1723 through mikrotik firewall to inner RRAS pptp server it works fine but the connection get dropped automatically 3 minutes after you get connected. It sounds freak but it really happens. I’ve noticed in “IP > Firewall > Connections” filtering by connection type pptp, when you get connected it shows with TCP State “CLOSE” automatically, not established as allways but can’t change that and don’t know why it happens.
I’m stucked!!! Both pptp ways locked my boss is getting me sick!!
But the strange thing, when I removed this interface it still keeps on working. To be sure I have rebooted and after that is still works.
