That is great Marius! Always nice to see spectacular increases in performance in an existing program :-) This should make it usable in practice. Let's see how it works on Ronen's small router! (maybe I do an experiment myself on a RB951G or RB750 when I can borrow it for this purpose) Rob

Mikrotik RIPv2 AMPR Gateway Setup Script 1.6
by Marius Petrescu 12 Apr '16

12 Apr '16

Hello, I managed to optimize/change the Mikrotik router script so it has some 50% or less run time and less processor load compared to 1.5. Download links (rsc script): http://www.yo2loj.ro/hamprojects/ampr-gw-1.6.rsc http://yo2tm.ampr.org/hamprojects/ampr-gw-1.6.rsc Only main script as text file: http://www.yo2loj.ro/hamprojects/ampr-gw-1.6.txt http://yo2tm.ampr.org/hamprojects/ampr-gw-1.6.txt Have fun, Marius, YO2LOJ

Marius, Do you have any explanation why the script requires a powerful router? Is it just the general inefficiency of the MikroTik scripting language execution, is there some operation called by the script that takes a lot of CPU, or is there a chance that by using a more efficient algorithm (e.g. optimization of the case that nothing changes for an entry) a lot of performance could be gained? I ask this because your approach is of course the easiest to have everything integrated on a single router, vs two alternatives that could be considered: - run a Metarouter which does the multipoint IPIP tunneling and runs ampr-ripd - run a Metarouter which runs the python scripts that update the config on the main router Rob

Re: [44net] Source address based routing on MikroTik ?

> Yes, you do it by applying a routing mark, then have a different route > table for the mark. Here is an article about it Besides the generic method of using the Mangle table to apply a routing mark, there is also the simpler method of using IP->Routes->Rules to directly select a routing table based on a source address/network.

Source address based routing on MikroTik ?
by R P 11 Apr '16

11 Apr '16

Hi there Is there any way to do source address based routing in the miKrotik ? The idea is to route only local 44 net trafic to the tunnel and other adress spaces that live on the network to route directly to the internet ? If yes (im almost sure Mikrotik can do it) how ? What is the command syntax ?

Mikrotik RIPv2 AMPR Gateway Setup Script 1.5
by Marius Petrescu 10 Apr '16

10 Apr '16

Hello, I just updated the gateway setup scripts for Mikrotik routers to make the system more robust. It now consists of 2 scripts: - the parent script (update_amprgw) which is scheduled every 5 minutes, on 1 min pat the RIP announcement - the actual update script (ampr_gw) which called from the parent script The parent script will: - prevent run overlaps - after 3 unsuccessful schedules will consider the update script failed end will enforce a run - it will prevent tunnel updates if less than 100 RIPv2 routes are available The scripts and schedule entry are in Mikrotik export format. The file can be copied into the router and loaded using the import command or the content copy/pasted into the console. After this step, edit your config in the ampr_gw script under system->scripts and enable the scheduler entry (disabled by default).

But I already told you to use /export to get the config which also explains how you could do it manually. Rob

> marius already did all the legwork and wrote scripts that do this on the > Mikrotik. It requires a more powerful MikroTik than he has. I looked a bit at the solution of running a virtual Linux system on the MikroTik but I can't find a reasonably current ready-made Linux image (the one on the site is dated 2010) and I don't think I will setup a cross-compilation environment just for this pointless experiment. (I use a Pi when I need things like that) Also, lately MikroTik have been reducing Flash memory size in their smallest models, making it difficult to impossible to run arbitrary (non-RouterOS) virtual machines on them. (my RB2011 has 128MB Flash, the smaller boxes used to have 64MB, but now the smallest boxes have 16MB Flash. clearly cost cutting is important to sell a router for $39 or less) Rob

> changed the ip route 0.0.0.0 to point to the UCSD interface (to tunnel outgoing traffic of my 44 net to the tunnel ) Did you first add a route to 169.228.66.251 via the gateway that was used for 0.0.0.0/0 before? There must be some way to reach the tunnel interface outside of your 0.0.0.0/0 route! (or else you build an encapsulation loop) It is easier to start with routing only 44.0.0.0/8 to the tunnel interface. > If it matterthe OS version is 6.29.1 > and system firmware 3.24 Why not update it to the current version? It can be done at the click of a button, no separate maintenance contract required as with Cisco. > Is there any command that i can grab the configuration of the router (like in Cisco the command "Show running config" ) ? /export You can also do: /export file=myrouter Then download myrouter.rsc from "Files" and delete it. You can then examine the file using a text editor, e.g. "wordpad". Rob

Tunnel to UCSD refuse to work on my mikrotik
by R P 09 Apr '16

09 Apr '16

Hi group the tunnel traffic from mikrotik refuse to work I have done the followings Gave the wan (called ether1-gateway) ip of the outside (in my case 10.0.0.180 (it connect to the ISP router DMZ zone)) Gave the Lan the gateway 44 IP in my case (44.138.1.l) unchecked the NAT option created tunnel interface (called UCSD) with IPIP and source address of 10.0.0.180 and destination address of the amprgw at UCSD changed the ip route 0.0.0.0 to point to the UCSD interface (to tunnel outgoing traffic of my 44 net to the tunnel ) same config exist and working at the Cisco here ( i have disconnected it and plugged the Mikrotik instead) . I see that the tunnel interface receive data and send data but i have no connectivity when i look at the firewall connection tab i see the incoming DNS attacks to what used to be the mikrotik address when it was connected to the 44 net few days ago so it looks like that incoming traffic work ok from the ucsd tunnel side I disabled all firewalls rules (the one that came with the router out of the box) and no change When i do trace route from the router it stop at the 10.0.0.180 IP and not go afterward What am i doing wrong ? the same setup work at the CIsco If it matterthe OS version is 6.29.1 and system firmware 3.24 Any help would be more then appreciated Is there any command that i can grab the configuration of the router (like in Cisco the command "Show running config" ) ? regards Ronen - 4Z4ZQ http://www.ronen.org Ronen Pinchooks (4Z4ZQ) WebSite<http://www.ronen.org/> www.ronen.org ronen.org (Ronen Pinchooks (4Z4ZQ) WebSite) is hosted by domainavenue.com
