Re: FastTrack + Simple Queue (Max Limit for Target Upload/Download

You could try making a specific rule firewall rule for this traffic and putting that above the fasttrack rule, maybe also add a specific "established,related" rule for this traffic.

After that you can use marks/queues/limits for this traffic and use fasttrack for the other traffic.

Re: RB750GL Slow Routing with new ISP

The connection to the new ISP could have higher latency and/or packetloss (especially if it's a wireless ISP). This also leads to lower (single stream) speedtests. Have you tried the (multi-connection) DSLreports speedtest? http://www.dslreports.com/speedtest And do you have any numbers on latency/p...

Re: Mikrotek RB750GR3 support DES?

I agree that using old algorithms is not advisable, please try using AES + SHA256.

If fore some reason you _have_ to use them: RB750GR3 does support unaccelerated DES + MD5 and hardware accelerated 3DES+MD5.

Are you sure the transport layer (the "cloud" in your picture) doesn't strip the extra vlan tags?

Re: RB4011iGS: No 'Microtik' wireless network to connect to for configuration?

So you don't get an IP address through DHCP if you connect wired ( on any port but port 1 )? Are you sure you did a reset after 5 seconds and not 10 seconds (which puts the device in CAP mode)? If you have a serial cable you could also try connecting to the (RJ45) serial port on the back of the rout...

Re: firewall is pushing the cpu

Also look into Fasttrack https://wiki.mikrotik.com/wiki/Manual:IP/Fasttrack this can improve performance dramatically.

Re: Mikrotik sniffer droped packets

Hello, I want to know if there is a method to use the sniffer tool or something else to catch all dropped traffic from firewall. I would like to know if there are some rules that drop something and then allow the traffic if this is good. I would use it for debug purpose. Is there a solution with th...

Re: Poor VPN Performance with SSTP VPN

Do you really need SSTP? It’s TCP protocol, it means it’s process of acknowledgement. If you can choose from one of those i’ll play with l2tp and manually set up IPsec I second this, SSTP is suboptimal for a site-to-site VPN because it uses TCP. I would look into using IPsec for this link, which wi...

Re: Poor VPN Performance with SSTP VPN

Just some quick remarks about the IPerf tests. The SSTP VPN connection however has been delivering very poor performance of around 4-5Mbps maximum. This is evidenced by Windows 7 client PCs in the remote office accessing the file server (Windows Server 2012 R2) in head office where file transfers ne...

Re: Stability problem of the SSTP/OPENVPN [SOLVED]

I see the exact same problem with the ovpn and sstp servers on a HEX v3 router (RouterBOARD 750G r3). This might have something to do with this specific model. I upgraded the routerboard firmware to 6.42.3 today in the hope of fixing this issue. (routerOS was already on 6.42.3, there do not seem to ...
