Mikrotik Firewall
by Rob Martin 29 Aug '20

29 Aug '20

Greetings, I have been writing a lot of Mikrotik Firewall rules lately. I know I am getting better at it, but the more I know, the more apparent it is that there is a lot more to learn! I have questions about how best to use the Mikrotik Firewall. The lines below are to illustrate the issue, and are not comprehensive. Also, I have used extra spaces to make it easier to see what I am doing. Let’s say I want to block a list of address ranges, in this case (some of the) Bogons, those non-routable addresses that should never be the src-address of any incoming traffic from outside my network. For whatever reason, traffic from Bogons shows up anyway. First, add the addresses to the address-list. /ip firewall address-list add address=10.0.0.0/8 list=Bogon add address=172.16.0.0/12 list=Bogon add address=192.168.0.0/16 list=Bogon Technique #1 – Drop incoming Bogon traffic in the Firewall Filter. The determination as to whether the traffic is arriving through the tunnel, and whether its src-address in on the Bogon list is performed twice, once for chain=input and again for chain=forward. /ip firewall filter add chain=input action=drop in-interface=Tnl src-address-list=Bogon add chain=forward action=drop in-interface=Tnl src-address-list=Bogon Technique #2 – Mark the incoming Bogon traffic prior to routing using Firewall Mangle – chain=prerouting - then drop it in Firewall Filter with two simpler rules. A single Firewall Mangle rule will mark everything in one rule. That is all it does. The two Firewall Filter rules that follow only have match the packet-mark. /ip firewall mangle add chain=prerouting action=mark-packet new-packet-mark=Bogon_from_Tnl passthrough=no src-address-list=Bogon in-interface=Tnl /ip firewall filter add chain=input action=drop packet-mark=Bogon_from_Tnl chain=forward action=drop packet-mark=Bogon_from_Tnl I think both of the above techniques will achieve the same result, blocking Bogon traffic arriving through the tunnel. Questions: 1. Which method is better, and by better I think I mean, which has the lowest impact on the performance of the router? 2. Does the answer depend on the number of the Bogons in the address-list? 3. Does the answer depend on where in the Firewall Mangle list the Mangle rule is positioned? 4. Does the answer depend on where in the Firewall Filter list the Filter rules are positioned? 5. Is there a way to measure any of this quickly with simple tools, and on a limited budget? Who out there is a Firewall expert?!! Rob K7QJ

Volunteers needed for Blyn Mtn deployment
by Bart Kus 30 Jun '20

30 Jun '20

Hello, We're deploying a new HamWAN site at Blyn Mtn (48.006678°, -122.972668°), but we don't have the volunteers to make it happen at this point. If you'd like to come help on July 5th, please email me. Need ground crew that can crimp and work lines, and could use a 2nd climber to split the load. From what I recall the road is easily passable, so no special vehicle required. And thank you! --Bart

Bart, I can't tower climb but can do ground duties. As the Jefferson County EC and a beneficiary of this site I want to support. 40 years experience with Motorola and wireless internet. I may be able to bring along one of my HamWAN experts. I was at the site on my motorcycle just last week. Road passible. 73 Dick Illman AH6EZ On Tue, Jun 30, 2020, 12:00 PM <psdr-request(a)hamwan.org> wrote: > Send PSDR mailing list submissions to > psdr(a)hamwan.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://mail.hamwan.net/mailman/listinfo/psdr > or, via email, send a message with subject or body 'help' to > psdr-request(a)hamwan.org > > You can reach the person managing the list at > psdr-owner(a)hamwan.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of PSDR digest..." > > > Today's Topics: > > 1.

VOTE: Blyn HamWAN Site
by Bart Kus 26 Jun '20

26 Jun '20

Hello, I've put together the spend request to deploy HamWAN coverage to Blyn Mtn: https://docs.google.com/spreadsheets/d/12lho76dJUSlXiJRy0UzYlnG66JHQeDzPMBZ… The site is at (48.006678°, -122.972668°), has a 110ft Rohn 45G tower, will provide a high speed link between SnoDEM and Victoria, as well as providing regional omnidirectional coverage. Once HamWAN is installed, my understanding is there will be some DMR repeater(s) going on the air there. There is already a corresponding dish @ SnoDEM for this site, and has been for years. We've also got confirmation that we'll be able to get a dish installed @ Triangle for the Victoria end. 24-hour director voting period for this starts now. My vote for this is: yea. --Bart

I was just up at Blynn and although I could easily see Sequim, Port Angeles was not a slam dunk because of terrain blockages. I think that a sector towards Sequim/PA, a Sector towards Cape George/PT, and a third sector facing south towards Quilcene would be most beneficial to Jefferson and Clallam counties. 73 Dick Illman Jefferson County ARES EC On Fri, Jun 26, 2020, 12:00 PM <psdr-request(a)hamwan.org> wrote: > Send PSDR mailing list submissions to > psdr(a)hamwan.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://mail.hamwan.net/mailman/listinfo/psdr > or, via email, send a message with subject or body 'help' to > psdr-request(a)hamwan.org > > You can reach the person managing the list at > psdr-owner(a)hamwan.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of PSDR digest..." > > > Today's Topics: > > 1.

Neat Milky Way video brought to you by HamWAN

Figured I'd share a frame of the video stream showing the Milky Way and Mount Rainier from the new Rattlesnake camera. Focus could probably use some manual tuning. :) --Bart

Rattlesnake mission this weekend
by Bart Kus 25 Jun '20

25 Jun '20

Hello, I'd like to get some climbing + non-climbing volunteers for this weekend's mission to Rattlesnake. While the site is open for business as of last weekend, some work is still required. This will be hopefully the last trip to Rattlesnake this year. The work list is: 1) Install ice shield on stubby tower to protect 60GHz dish. 2) Bring down Baldi dish from Rohn25 tower, install RF shield, upgrade modem, re-install and re-align dish. 3) Install missing cable cushions on the big tower. We'll be meeting at the gate on Saturday @ 9:30AM and going up from there. If you'd like to come help out, please email me for details. Thanks, --Bart

Looking for StationBox mounting plate
by Doug Kingston 24 Jun '20

24 Jun '20

Dear PSDR members and friends, We have a StationBox <https://streakwave.com/itemdesc.asp?ic=SBX%2DS%2DCC&eq=&Tp=&o1=0> in inventory which is useless for most functions because it's missing the plastic plate on the back that is designed to mate with the back of a Ubiquiti sector antenna. The plate is white and about 2" x 3 " with 6 mounting holes (see photo). If you have one, you can make this box useful again. Please email me if you have one lying around surplus to need. If you mounted a StationBox on an mANT30 dish, you may have one spare since the mANT30 provides a different mounting plate. -Doug- HamWAN Inventory Flunky [image: IMG_20200624_160944.jpg]
