Mikrotik IPsec Site to Site VPN – HOW TO

March 10, 2013   

IPsec Site to Site VPN Mikrotik Setup- HOW TO by Travis Kenner

This is going to be a shotgun setup example. I do not show how to setup Clients or DHCP servers on each Mikrotik for the LANs. This is just and example of setting up the IPsec so you may have to fill in the blanks. Hopefully this is enough to fill in the gaps with for an IPsec connection to make a Mikrotik Site to Site IPsec VPN Tunnel.
Enjoy 🙂

 

PLEASE NOTE: For any configuration examples please visit the Mikrotik Forums for help and support. There are some really knowledgeable people on the forums who will be able to help you with your individual setups.

PLEASE NOTE: You need NAT bypass rules for the IPsec negotiation. I will be updating the pictures to help more with visual clues and setup help. Also I will be clearing up any mistakes I have made in IP addresses or any other technical mistakes as well as putting pictures back in for IPsec Peer examples.

Equipment:
2 Rb750GL Mikrotik with Router OS 6.0rc11

 

Server Side Mikrotik Setup:

CISCO Rollover cable using a regular Patch Cable

March 9, 2013   

If you dont have a roll over cable for connecting to a Console port on a CISCO router then you can also make and keep with you this handy Serial Adapter that turns a Regular Patch Cable into a roll over cable you can use toconnect to a Console port on a CISCO device.

Go out to any place like Memory Express or Radio Shack / The Source and get a Ethernet to Serial Adapter that comes un pinned and then you can make your own adapter.

Pictures will be uploaded in next fix but here is the pin out.

Mikrotik Firewall Mangle and Queue Tree example

Mikrotik Firewall Mangle and Queue Trees Example HOW TO

by Travis Kenner

PLEASE NOTE: For any configuration examples please visit the Mikrotik Forums for help and support. There are some really knowledgeable people on the forums who will be able to help you with your individual setups.

http://forum.mikrotik.com/

Equipment:
Mikrotik RB750GL Running Package version 6.0rc11

NOTE: I am no Mikrotik expert and definitely don’t fully understand Mangling and Queues but I will correct and add to this blog as I learn.

I decided to put this together after I could not find a clear and concise example of how to use the Mikrotik Mangle and Queue functionality.

Marking a connection? Packet Mark, route mark, connection mark, Queue Tree???? Anything I found was vague, felt incomplete or just didn’t explain enough of the what and the how.

So What is Mikrotiks IP Firewall Mangle?
Here is the Wiki that explains it: http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/Mangle

Here is the Summary copied straight from the Wiki:
Mangle is a kind of ‘marker’ that marks packets for future processing with special marks. Many other facilities in RouterOS make use of these marks, e.g. queue trees, NAT, routing. They identify a packet based on its mark and process it accordingly. The mangle marks exist only within the router, they are not transmitted across the network.

Word Freezing when Pasting Internet Explorer Content to new Word Doc

March 2, 2013   

Recently I ran into a problem where I was trying to paste some very cool Mikrotik info I found into a word doc so I could look at it later. I noticed that if I pasted it into notepad it worked great. I also noticed that what was so odd is that there was a file I could not open I got from somebody.

I could open other doc files but not this one.  read more …
