I have been running a MikroTik RouterBoard in the house for a couple of months now (the RB750G) and I am very much loving the thing. But one thing you may need to do is setup VPN connections… Here are some tips on how to create a VPN Server and Client on your RouterBoard.
to setup a client, you need to do the following:
What does that all do? the first line creates an l2tp-client interface, pointing at “servername” with the username and password set. encryption, etc is enabled… Line 2 then enables the client. Line 3 sets all traffic comming from networkaddress/24 (for example, 192.168.0.1/24) to be sent though the VPN. any traffic going into networkaddress (same example) is not sent though the VPN. Line 4 creates a gateway, for all addresses (0.0.0.0/0) to use the VPN address. finally, NAT Masquerading is enabled on the VPN interface.
there are more advanced things you can set above… some examples I can think of are as follows:
- There should be no good reason to limit the amount of VPN connections you have… in theory, you could have multiple…
- for the mangle rule, set the src-address to a single machine in your network. that way, it gets VPN only connections. Also, you could set the dst-address to a single address or network to send only traffic going to a given server though the VPN… Example would be Netflix US traffic to a US VPN server, BBC iPlayer traffic to a UK VPN, etc.
- the example above uses L2TP, but PPTP, SSTP and OpenVPN are also available.
As mentioned above, L2TP, PPTP, SSTP and OpenVPN servers are available on RouterOs. Details on setting them up are available on MicroTik’s Wiki at the following locations:
