I have configured a PPP connections between two mt, but the connections go up and down continiously

* DSL on both sides is up.
* On both sites there is a router that does the NAT to internet
* Site1 MT version: 6.4 , Site2 MT version: 5.26

* Site1 has static IP and runs the PPTP server
* Site2 has dynamic IP and initiates the connection

* The PPP connection disconnects at random times and after a few hours and hunderns attempts comes back. Then again.....

* Site2 MT: IP > Firewall shows hundrend of connection idling
The same time, site1 MT does not have an active PPP connection
The screenshot is taken from Site2 MT (client)
* If deleting the user (PPP > Secrets) and create again the user, with exact same details, PPP connection comes back at once!!!!!!!!!!!!!!!
Otherwise, I have to wait hours so the PPP connection comes back online

* These are the logs from site2 MT (the client)
While these logs are being generated, I am continiously connected to MT (through internet) from site1
Hence there is connectivity

Any idea what can cause the problem?
Thank you

Get correct ppp profile

This is the profile used

I cant find any error...

Any ideas please?

Can you ping the ip you try to connect to?

Is pptp enabled in ip firewall service port?

Use following easy profiles:

Server:

ros code

#default
/ppp profile add change-tcp-mss=yes name=ppp use-ipv6=default

#user
/ppp secret add name=xxxxxxx password=yyyyyyyy profile=ppp remote-address="the address you give to client"

Client:

ros code

/ppp profile set 0 change-tcp-mss=yes use-compression=no use-encryption=required use-vj-compression=no
/interface pptp-client add allow=mschap2 connect-to="publicip of server" disabled=no name=pptp-out1 password=yyyyyyy profile=default user=xxxxxxxxxxx

then I get:

ros code

/interface pptp-client> monitor pptp-out1 
          status: connected
          uptime: 3m10s
        encoding: MPPE128 stateless

PS, why you use different local address?


Is it possible to run l2tp? (better in a router to router setup) Only benefits I see to pptp is the possibility to connect directly via a windows computer, without any advanced config for ppp.

Can you ping the ip you try to connect to?

Is pptp enabled in ip firewall service port?

This is what I see:
I use different local address in order not to connect them directly in my LAN.
Then I can apply various rules based on their IP


In case I dont find a permanent solution, I will move on to ipsec vpn
