For a wISP, WiFi6 is the largest single improvement *ever* in wireless performance on single streams, then stacking 4x4 and 8x8 radio options with 2 way MU-MIMO.....

dude is running on a dedicated RB750Gr3 which has a 4-core cpu ...

Good news works with MMIPS 4 Threads. NO 4 core https://mikrotik.com/product/RB750Gr3.
Are u 100% sure monitoring any mikrotik device ? No snmp just ROS protocol ?

2jarek

I am on dude 6.47.8 without any problems ...
(Max connection speed is 1GB/s here)

just my 2c

Than try run dude on multi-core CCR. No old single core MIPS.

2jarek

Downgrade....6.45.9 From march 2020 last good for dude.

2jarek

In this version Dude server on multicore CCR not works properly.

Last working on CCR version dude is 6.45.9. After years of fighting the NV2 TDMA mikrotik trash, the migration to Cambium has followed. Now it's time to finish the dude server. The next one will probably be CCR.

Shame for mikrotik not being able to set the asymmetrically maximal MCS on both sides manually.
LOW mcs for UPLOAD gave us better jitter & TCP speedtest for NV2.

2jarek

Would really like to know as well because having 20 CPE's on a sector in very noise environment and only able to get max 20mbps from the sector is a bit low in today's market. That's very low. Sounds like you need to be looking for another frequency! What AP are you using? Im using 922UAGS-5HPacD (...

2jarek

802.11 n or AC is irrelevant for this type of traffic. RTS / CTS will not help. You need the real TDMA protocol. U can try mikrotik NV2 works well for 5-10 device. Or buy cambium & elevate miktotik OLD 802.11N 600Mhz SXT / LHG.

RC4 for ARM works much much better for NV2 & pure 802.11 too. Here MIPSBE AC Basestation + ARM CPE good signal 50 dB but non line of sight for pure 802.11N mode. Before RC4 latency spikes for idle mode / no traffic only.

RB411AH has 100mbit fdx ethernet..... how possible >180 mbit/s in UDP ????

2jarek

hello yes i used two antennas on each card,i did an outdoor test over a couple hundred meters using a dual polarized antenna with RB433AH's either side using the SR71A's.I also had two pc's connected to each board on both ends and used the mikrotik bandwidth test to do the tests through the boards ...

RouterOS proxy cache youtube video ?

2jarek

And ?
Rb not for winbox/terminal games....

2jarek

I use L7 but why MT off good fast way to mark this traffic ?
No remove from winbox, console and no changelog, hidden surprise :/

Block probably the best p2p network emule/cad ? No comment in Poland emule is basic Internet service.

2jarek

LOL ask network admin....

BitTorrent (40-73 proc.), eMule/eDonkey (14-57 proc.) Gnutella (2-9 proc.)

Ok i make it but tomorrow I first test new RB 333 on only NAT for only one PC. Try NAT 8/8 mbit traffic i think same result NAT is not easy for PPC CPU.

2jarek

ip firewall mangle add p2p=edonkey action=accept chain=forward

In RC 1-6 this rule work , In RC9, RC 11, RC13 this rule not work. Edonkey detect NOT WORK no one packet cath.

Plz not told encrypted traffic bla bla.....I make downgrade in 3 min &..... magic rule work great.

2jarek

I m winbox user but in terminal I try this:

ip firewall nat add action=masquerade out-interface=netinterface chain=srcnat

Show CPU use, packet per second & connections for me: CPU 90-99%, 1100/900 pps(MAX), 3000 connection its heavy for br333.

2jarek

Routing, bridging is true but not in NAT. Pentium III 500 is many time faster make NAT than RB 333.

2jarek

Routing bridging OK work great, but NAT no!!! use D-link 10$ router better.

2jarek

1100/900 pps max no virus no heavy p2p.
When simulate virus or heavy torrent traffic RB 333 making NAT worse than D-link 10$ router.

2jarek

You use Masquerade/NAT 1:1 or Connection tracking ?

2jarek

No encrypt wireless no problem eat maybe 10% CPU. I try LAN to LAN same result.

2jarek

When CPU use 95-99% - DNS cache on MT lag or not work, latency not good. When disable quee 8/8 mbit symmetric traffic kill RB333, in BRIDGE MODE 80/80 mbit possible http://www.vpx.pl/up/20071203/288372c78dba45c7da902971f82865b9f7862150257.jpg http://www.vpx.pl/up/20071203/288434e17f2a258effb8ae350f8...

:for x from=3 to=254 do={ /ip address add address=(zzz.zzz.zzz. . $x) netmask=255.255.255.0 interface=wan}

ON RC1, RC6, RC9 work good....

How are possible all new versions have a lots of new bugs ? randomize bugger ? Maybe coders respect their work so have that for ages ?

2jarek

RB411 have extra frequency 2.3-2.5 ghz ?
Need small cheap CPE on 5-6 ghz no on full of noise 2.4ghz.

Man read again posts in this topic.

2jarek

OK

If you need isolation between interfaces use bridge firewall.

2jarek

Me once but i use RC9 one week.

2jarek

10-20 active emule host in network.
NAT on RB333 try put on top forward chain new rule accept edonkey packets.
10 minuets 0 packets......: EDONKEY PROTO DETECT NOT WORK IN RC9.

2jarek

I no block only mark in rc1 it's work.

2jarek

Rc9 not mark any emule connections DC,torrent, warez but no emule :/

2jarek

Need button "make static" when add using copy list new static list sometimes not work, sometimes system unstable - "interface unknown" need reboot.

2jarek

RB333 performance in NAT is good but RB5xx @ 400mhz have better or similar performance maybe "QUICC Engine RISC" not work yet ?

2jarek

3.0 RC1, 802.11b, no have limit deauth frame if I try force connect ping for users from access list growth & transmission cut.

2jarek

Hi i need use RouterOS firewall to operate on name adress no IP.
Linux iptables is simple command:
iptables "-p tcp -s http://www.xxxxxxx.com"........
On RouterOS ????

True 802.11b works fine but 802.11g Edimax >> disconnect extensive data loss (SNR 30db)
