Compare Files with DiffMerge

Leave a comment

I came across a handy little application called DiffMerge that allows you to compare multiple files and make changes while open.  This is extremely useful when comparing multiple MikroTik configuration files.  Previously I used sdiff, but I think this is much easier to use.

DiffMerge is a free application and can be used on OSX, Windows, and Linux.  The download can be found here.

AT&T 3G with Gobi 2000 on Routerboard 411UAHR

Leave a comment

This is my first setup with 3G on a Routerboard.  It took a little longer than I wanted to figure everything out, but I eventually got it working.

 

The steps that made it work.

  1. Place the UMTS drivers in the /firmware directory on the Routerboard (You should be able to get them from whom you purchased the card.)
  2. Install the Gobi 2000 and power on the router.
  3. Shutdown the router and install the SIM card
  4. Add the ppp-client with the settings below. Continue reading AT&T 3G with Gobi 2000 on Routerboard 411UAHR →

DNS Resolving for PPP Clients

Leave a comment

Sometimes you will need to connect to a router that either has a dynamic IP or a domain name instead of directly to the IP address.  This is easily achieved using RouterOS  with a simple script.  Using the script below you will need to change PPP-INTERFACE to the name of your PPP interface and VPN.YOURDOMAIN.COM to the domain name of what you are trying to connect to.

/system script
    add name="CBrown-VPN DNS" policy=\
    ftp,reboot,read,write,policy,test,winbox,password source=":global pptpinte\
    rfacename \"PPP-INTERFACE\"\r\
    \n:global pptpdnsname \"VPN.YOURDOMAIN.COM\"\r\
    \n:global pptpdnsip [:resolve \$pptpdnsname]\r\
    \n:global currentip [/interface pptp-client get \$pptpinterfacename connec\
    t-to]\r\
    \n:if (\$currentip != \$pptpdnsip) do={ /interface pptp-client set [find n\
    ame=\$pptpinterfacename] connect-to=\$pptpdnsip}\r\
    \n}"

Open NAT on Xbox Live

2 Comments

Here are the rules I use to open my NAT on Xbox Live.  Xbox.com says to “open” ports 88udp, 3074udp/tcp, 53udp/tcp, and 80tcp.  Assuming you can browse the internet you don’t need to NAT 80 and 53 to your Xbox.  These are just HTTP and DNS traffic which you should already have working.  The ports used for actual gaming are 3074 and 88.  One is probably used for the actual game play and the other is more than likely used for voice.  I am not sure and could be completely wrong, either way you need to NAT them both.

PtP Bridge With 802.11N and NV2

1 Comment

Here is the configuration for a Point-to-Point link that can be used with a number of MikroTik devices.  With this example I used two StationTik 5G’s but could be used with SXT’s or any other Point-to-Point devices.  You might need to change your frequency depending on usage in your area.

AP Side

/interface bridge
add l2mtu=1600 name=bridge1
/interface wireless
set 0 band=5ghz-onlyn channel-width=20/40mhz-ht-above disabled=no frequency=5745 \
    ht-rxchains=0,1 ht-txchains=0,1 l2mtu=2290 \
    mode=bridge nv2-preshared-key=yourpass nv2-security=enabled ssid=PtP wireless-protocol=nv2
/interface wireless security-profiles
set [ find default=yes ] group-ciphers="" supplicant-identity=MikroTik unicast-ciphers=""
/interface bridge port

Disable Access During Certain Hours

6 Comments

Recently I have needed to restrict access to the internet during certain hours.  This is very easy to achieve with MikroTIk using a few mangle and filter rules.  I currently have this configuration on a RB751 so I am using a bridge for the LAN.  I have ports 2-5 switched together and then bridged the wlan1 and ether2 (the master port) together.  Instead of just restricting everything on the bridge I wanted to be able to allow access to myself and certain others during “restricted times”, and this is why I used mangle to mark connections and filter via the connection marks.

Here you can see the two rules mark the connections from my allowed devices.  The last two rules mark everything else in and out of the DHCP bridge.

/ip firewall mangle
add action=mark-connection chain=forward comment="Mark CBrown Computer" disabled=no in-interface=DHCP \
    new-connection-mark=Allowed passthrough=no src-mac-address=XX:XX:XX:XX:XX:XX
add action=mark-connection chain=forward comment="Mark CBrown iPhone" disabled=no in-interface=DHCP \
    new-connection-mark=Allowed passthrough=no src-mac-address=XX:XX:XX:XX:XX:XX
add action=mark-connection chain=prerouting comment="DHCP Upload" disabled=no in-interface=DHCP \
    new-connection-mark=DHCP passthrough=no
add action=mark-connection chain=postrouting comment="DHCP Download" disabled=no new-connection-mark=DHCP \
    out-interface=DHCP passthrough=no

Queue Tree Setup for Multi-WAN

Leave a comment

This article goes with Marking Traffic for Queueing.

I did use the new queue type (mq-pfifo {multi-queue packets-first-in-first-out) in this setup and it worked fine.  I also had it setup with the default and it worked fine as well.

You will setup your trees per WAN connection. One for each global-in (download) and global-out (upload) for each WAN.

Make sure to send the correct packet marks from each WAN to each queue tree.
