PPTP Connection between Splynx and Mikrotik
If Splynx and your Mikrotik router, are on different networks, the solution to this scenario is through creating a PPTP tunnel between the two.
Configuration on Splynx:
First install the pptp server. In the CLI of your Splynx server, run the following command:
sudo apt install pptpd
Then you have to add the DNS servers, you can do this with the following command:
Once the editor has opened, change the following:
#ms-dns 10.0.0.1 #ms-dns 10.0.0.2
To the addresses below:
ms-dns 126.96.36.199 ms-dns 188.8.131.52
After that you have to add the pptp secrets. This can be done with the following command:
Here you can Add users and secrets as depicted below:
# Secrets for authentication using CHAP # client server secret IP addresses user1 * user1-password * user2 * user2-password *
Now you have to allocate local and remote IP's. Run the following command:
Then Add or Edit the following.
localip X.X.X.X remoteip X.X.X.X-X
Then in the file:
Uncomment the following line.
net.ipv4.ip_forward = 1
Save the changes:
sudo sysctl -p
Configure the Firewall for IP Masquerading.
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
Restart pptp daemon to apply changes.
sudo /etc/init.d/pptpd restart
Also you have to add static routes to your local network ranges, that will point to the tunnel interface, for example :
route add -net 10.0.1.0 netmask 255.255.255.0 gw 172.16.200.2
Where 10.0.1.0/24 is the local network and 172.16.200.2 is the IP address of interface (or it can be set to ppp0)
On the Mikrotik router side:
/interface pptp-client add connect-to=localserverIP disabled=no name=pptp-out1 password=user1-password user=user1
