Hello,
Mikrotik released its new RouterOS version 6.41, with some changes
affecting the gateway script.
I released an updated script version to address this issue.
For those using pre-6.41 ROS, the update is not necessary.
If you want to correct the script manually, just delete the line
referring to neighbor discovery disabling in the 'add new tunnel'
section of the ampr_gw script whic states:
/ip neighbor discovery set $gw discover=no
As usual, download at:

Marius, YO2LOJ
Currently running on a Raspberry Pi in a pfSense DMZ on residential Dynamic
IP. Marius’ ampr-ripd compiled with no issue, the scripts from my linux
gateway that I worked on with Lynwood work perfectly with no modification.
Need to do a little tweaking with iptables firewall as my network
implementation is different from what it was when I was running one box.
Diagram:
(Internet)===<pfSense>==(DMZ)==<Raspberry Pi>==(44.98.63.0/29)
- I’m NAT forwarding ipip traffic that hits the pfSense external interface
to the DMZ (usb NIC) interface on the Pi.
- tunnel script and ampr-ripd run on the pi creating tunl0 on the pi
- local AMPR segment on the Pi native interface.
- pfSense NATs outbound encapsulated traffic making it appear as if it
comes from the pfSense box.
- My gateways appears on Marius map.
Working on documentation for the wiki and will post by weeks end.

Hi Tom,
Some tome ago I was fiddling with pfSense to make it my gateway. I
abandoned this idea because there was a couple of key issues for me:
- BSD needs a device for each IPIP tunnel, this gets the things much
more harder to setup;
- PfSense does not have the protocols used enabled by default, needing
manual edit of the web interface after each update. You have to do it by
yourself every time;
- Linux has ready made scripts to get the job done. These scripts were
made by good hams here and tested by several other people. It is easier
to create a small virtual machine and put a 256MB RAM Devuan working
than creating a gateway using BSD.
- PfSense team is minded to get the commercial way of pfSense as a
product, so do not expect any support to get the things working. Their
support forum is getting more unconcerned every day.
If you are still inclined to use some type of BSD firewall as an AMPRNet
gateway, I suggest using OPNSense to start. It was a project forked from
pfSense, but today have only 10% of original code and have open source
as priority yet. Their forum is much more friendly and responsive.
OPNSense has all protocols listed in the web interface, so passing IPIP
traffic back and forth is more intuitive (I still would not use it as a
gateway anyway).
Hope this helps,

Greetings,
I was working with Dan Cooper last spring to turn my pfSense box into an
ampr gateway. At the time I was trying to learn how IPIP worked AND how
BSD (pfSense) worked. I'm pretty well versed in linux... BSD... not so
much.
At the time I moved to Linux and Lynwood helped me get my head around
how the IPIP tunneling works. After seeing the volume of traffic that
tries to crack into my residential ISP connection (even though it fails)
I've decided to put my ampr gateway into a DMZ. I'm currently in the
process of moving my AMPR gateway into a pfSense DMZ.
I work in a loosely security related position at work and I'm doing this
as a security measure to knock down some of the noise my Linux
gateway/Router/Firewall/AMPRgateway was seeing, mostly from Russia,
China and other places that I didn't research. My new AMPR gateway will
still be on Linux, actually Raspbian on a Raspberry Pi, but the only
traffic it'll ever see is encapsulated traffic and traffic from my
network because all of the other noise will be filtered by the pfSense
box and won't exist in my DMZ.
Out of the box the pfSense user interface doesn't have support for
ipencap or AX25. I did a little bit of research (google) and found an
older post on the pfsense forum about which files to edit to add ipencap
and ax25 to the UI. Also, I just asked on the pfSense subreddit to see
if there are any other places within the pfSense UI to edit which
protocols are available for use.
Is anyone else using this method to NAT forward IPIP traffic to an
internal gateway (in my case using pfSense). I'm looking to find out if
I've missed anything with the port forwarding before I move forward. I
know Brian (N1URO) was working with IPIP tunneling behind a NAT and I
think (THINK) this might work.
So... here's what I've done.
pfSense version is 2.4.2p1. File edits follow...
