What about not using API to configure the VLANs and whatnot at the end, instead generate a little .rsc with the appropriate config/commands in it, and /fetch and /import it?

pants6000

I just did a linux-native netinstall and it was so easy! A big improvement in comparison to the old gui netinstall on windows/wine. Three thumbs up!

pants6000

Do you have the SIP helper disabled?

Can you sniff closer to the SIP sever, like on the ingress interface to the openvpn server?

pants6000

I see that there are a few PTP models that support the wifi-qcom-ac driver.

Does using the new drivers/wave2 for a PTP link realistically gain anything?

I would love to hear from someone who has tried swapping between AC and wave2 on the same radios/locations.

pants6000

Disclaimer: I don't know if this will work on ROS but it feels like it should... and I am lazy. Try, for example, putting 192.168.200.1/24 on a bridge (with no ports on it, used like a loopback int on other platforms), and then adding a /32 route to each printer with the connected interface as the g...

Very weird indeed.

Do you know if your provider is using MPLS to transport this? It might be worth changing the MAC that starts with 4 to something else... I'm not (entirely) insane, read this:

https://mailman.nanog.org/pipermail/nan ... 89395.html

pants6000

Since ARP seems to work, can you mac-ping or mac-telnet between the two boxes? Do you see sensible things in the ARP table?

I wonder what the deal is with all the "bogus IPv4 version" stuff seen in the pcaps.

pants6000

If it works when it's triple-tagged like that, something in here must be stripping two layers of tags. What is your provider like? Do they do anything with tags? Are you using 0x88a8 s-tags because they want that or is that of your own doing? It might be helpful to post packet captures, it's easier ...

I like most of the webfig changes (including/especially the inline comments!), but the centered detail screens just strike me as odd, like the pages aren't rending correctly.

It show's that combination in the brochure, and even mentions that specific combination in the product description. Did you try it and are having problems? I didn't, I missed that in the description somehow... "Simply remove one of the current power supplies..."; implying that mixing them...

Exactly what I need to know... again. Thanks!

...
I have the same configuration, also mixed on the same rack devices with "-" and "+", and all work as expected, without short-circuits,
because both the AC and DC power sources are galvanically isolated

pants6000

Is the combination of a -48V power supply (PW48V-12V85W) and an AC power supply a supported configuration? CCR2116 is my likely target.

pants6000

Perfect, thank you!

My two-touch provisioning system is down to one-touch now!

pants6000

+1, I am already using CCRs for NAT but this would be awesome and simplify configuration greatly.

pants6000

Will there be -48V DC power supplies available for the CCR2116?

pants6000

Something like an RB2011 (which would be plenty fast enough) but with 6 to 12 rs232-over-RJ45 ports instead of all the ethernet ports. -48v input would be a nice bonus, like on the RB1100AHx4. ROS already has everything needed to be a console server, plus lots of things that console servers from the...

Yay for 60GHz/5GHz devices!

What is the fail-over mechanism between the 60 and 5GHz radios?

Is there a US/INTL version split like the other 5GHz devices?

I'd really like to see some internal pics if anyone can find them.

Does SWOS support rate-limiting both egress and ingress port speeds on CRS309-1G-8S+IN, CRS328-4C-20S-4S+RM, or CRS317-1G-16S+RM?

Do you have bridge port MAC learning turned on or off?

I wonder what CPU arch these new CCRs will use, should they exist...

pants6000

Does it fit/work?

pants6000

Always nice to see new telco powered stuff!

The new CCR-1036es, do they use soldered-in RAM or DIMMs or something else?

Actual tcpdump.

I know and use the existing local and remote sniffing tools, but they are not a satisfying replacement for a quick and simple "tcpdump -X" from the CLI.

Fine for me, such things won't get very far with The Boss and "techs", though, who are not particularly technical. Want something that I can just say "buy 10 of these" and be done with it. Such things exist but they are either very pricey or of questionable... everything. Perhaps...

Possible bug:
I have installed a fresh CHR with 6.40.9; the SIP helper port config is completely missing in webfig. It is present (and was enabled by default) in the ROS cli.

Try disabling CSMA if you haven't:

/interface wireless nstreme

The fine manual suggests that NV2 disables it automatically.

pants6000

I think this would be an awesome feature!

pants6000

+1, IMHO, DHCP traffic should probably be marked as high-priority regardless of (kinda stupid) ISP requirement.

pants6000

A source-address option for bandwidth test would be nice!

pants6000

FWIW, working beautifully on my 951Ui-2HnD at home. Don't see an inordinate number of sector writes, either.

pants6000

If you pay attention to what line of the config it stopped on, you can continue the import with "import from-line=", just increment the line number that it stopped on by 1.

But something like "continue import on error" would be a nice feature. +1

pants6000

Gonna resurrect this thread again... I got a CCR-1036 and the secondary power supply connector is not actually installed on the board, though I can see where it obviously goes. Other than having no connector, will the secondary supply work on the CCR-1036 as it does the other CCRs?

pants6000

Ahh, didn't see that when I was searching before... gonna order one now. Thanks!

Just want to confirm this before I spend my boss's money on one... thanks!

Also if your modem offers "ppp-ip extension", you should definitely try that--it will terminate the PPPOE session on the modem and bridge (well, not really bridge but the idea is the close enough) the IP data to the LAN port. That will relieve your Mikrotik from dealing with PPPOE so it ca...

pants6000

So it sounds like though you're in the same same IP subnet, you don't actually have a real L2 path between each other--it's probably vlan-per-customer, and the routes are /32s pointed at q-in-q interfaces. As a result, your ARP requests for the "other side" go unheard. If that's the case, ...

Maybe your conn. tracking table is filling up or something similar? Try turning the values in ip/firewall/connections/tracking down, especially the tcp established timeout.

I mangle tcp packets with the ack flag set and size < 64, then put those high up in my queue tree, which has an upload bandwidth slightly lower than the actual speed so as to avoid drops/buffering by the modem.

pants6000

Well, let's see what that capture looks like when you can get one... and us seeing as much of "/ip firewall export" as you're comfortable with may be helpful as well.

pants6000

Your ISP (or modem?) is giving you an RFC1918 "fake" IP, which is icky at best. I wonder if something upstream if you is at fault here... any chance of getting a real IP on your 'tik?

pants6000

Can you get a packet capture of this happening for us to ogle?

pants6000

Have you tried turning SIP ALG off in IP/firewall/service ports? Just disable the 'sip' entry on port 5060.

Are your ADSL modems also routers or are they just bridges?

PPTP/PPPOE interfaces (all PPP? more?) are disconnected then re-connected when clicking "OK" on their /webfig/#Interfaces.Interface page, even if nothing has changed. It probably shouln't do that.

pants6000

It'd be cool if there was a way that Safe Mode could be configured to be enabled from the very beginnig of a session, and you'd have to turn it off intentionally if you wanted/needed to (call it "cat mode".)

pants6000

A little late here... but in my testing (just now, on 6.25 between two CCRs), ROS does indeed copy the original DSCP value to the new header. You can also mangle it like any other traffic if you need to set/change the value. Lovely!

pants6000

*) improved boot times;

Reboot dropped from 42 to 32 seconds on my RB951Ui! Sweet!

pants6000

Cisco's "flex links" is another way to do that without STP.

http://www.cisco.com/c/en/us/td/docs/sw ... flink.html

pants6000

No, this config is for doing it in a routed manner. Your 'tiks DHCP server will do its usual thing, using local IP addresses, and the magling and routing will select and send the traffic you want over the VPN. I'm not sure that you can bridge over PPTP like that.

pants6000

Marking packets and then routing based on the mark is what you want, I think: ip firewall mangle add action=mark-routing chain=prerouting new-routing-mark=use-artgw src-address=192.168.10.0/24 ip route add distance=1 gateway=192.168.0.253 routing-mark=use-artgw ip firewall mangle add action=mark-rou...

Using webfig on 6.20, I can't correctly add a new DHCP network in IP/dhcp server/networks. The only field that will stay populated is the address field, the rest are cleared when I press apply. Tried from two different browsers. CLI/winbox work fine.

Yeah, the web interface in particular is pretty starkly commented/annotated in a lot of places. In this case (just to make it weirder?), if you want to do a qinq stack of VLANs with the outer ethertype of 0x8100, you don't use the "service tag" option--rather just add the inner VLAN as usu...

If you can put routes in the NAS, put in a route to 192.168.88.0/24 with the Mikrotik's VPN interface (10.10.10.1) as the next-hop.

It's no big deal here though, since it's unlikely the NAS will have to open connections to machines on your LAN.

pants6000

Sweet! It's kind of a dirty hack but it'll work for this just fine.

pants6000

The VPN server probably doesn't have a correct route back to your LAN at 192.168.88.1. You might try setting up a rule on the mikrotik to masqurerade connections going out the pptp interface, that way the VPN server doesn't need a route back to you.
