Note that this setup is only viable when one side is behind NAT. Otherwise you can specify DNS directly in GRE settings with ipsec-secret starting from 6.45.1.

Hey I would suggest to copy your current config, and then reset to default configuration, and then only selectively add some rules. The default config is "compatible" with vpns, and I think will be the easiest route. I will give it a try today, with my old 750GL. Thank you for the hint.

No, it does not. I know the L2TP, In case of L2TP RouterOS creates an interface, but in IKEv2 does not.

Trackboy

I tried lot of MTU, but i could not find the proper value. I tried L2TP/IPSec solution and that is working fine and assign public IP.

Trackboy

I tried several MTU-s so far, but the problem is the same. If i want to ping a host that is working fine, there is not packet loss. On the speedtest.net i get 100/100 Mbit/sec.
So the web browsing is very slow.

One more question. I have got a PPPoE connection with dynamic IP. I tried the tunnel with this connection. The speed was around 2-3 Mbit/sec. The ping is perfect and i do not have packet loss.

Trackboy

I tried with IPIP tunnel, working very well. Thank you very much for your help and your patient : ) This is really helpful and valuable for me.

Trackboy

It should work with GRE too ?

Trackboy

So i have got a GRE tunnel that is working fine between the CHR and home Mikrotik. On the CHR there is only one ether1 interface with 2 public IP addresses: 217.144.X.X/24, of course they are from the same range. I added only 217.144.X.119/24 to ether1. Mikrotik GRE interface IP address: 172.16.1.1/...

Trackboy

I made an encrypted GRE tunnel with the IPsec secret feature. 172.16.1.0/30 is the GRE tunnel ip range.
On CHR added 10.10.100.0/24 route, this is behind the 951G. That's it.

Trackboy

I made a GRE tunnel between the 951G and CHR. The tunnel is working. I added routing mark too.
I added public IP to my server statically. But does not work. I can not find proxy arp feature in the GRE interface.

Trackboy

Thank you very much for the help, i will give it a try : )

Trackboy

I would rather make a tunnel between them, and i would like to assign the IP to the server statically.
Maybe EoIP tunnel would be good for this ?

Trackboy

Hello everybody! I have got a Mikrotik CHR with 2 public IP addresses. I would like to assign one of the IP address to my server.

We need 100 Mbit/sec tcp speed in one direction,it is impossible with sxt, that's why need at least 28 dBi dual chain antenna, and powerful routerboard with mini pci, anyway the 28-30 dBi Rocket dish is only 64cm, and the 32-34 dBi is 97,2 cm

Trackboy

I am not an expert, but 54 km for Sxt devices is definitely too much, check that link that i put here, that is 46 km link with Ubnt 34 Rocket Dish and Dbii cards and RB 433AH, i know the equipments are very expensive, but we are planning similar links for 22 and 30 km links

Trackboy

Yes need to align perfectly, i know, here is another one interesting thread:

http://forum.mikrotik.com/viewtopic.php?f=7&t=60932

Trackboy

Nice performance, we are planning to start an WISP, so not impossible to achive the 100 Mbit/sec, anyway i counted with Rocket Dish 32-34 dBi and Dbii cards around -52 dBm signal strenght on 22.43 km, but this is just theory

Trackboy

Nice, and what is the tcp speed of this link?

Trackboy

The first link is 22,43 km, and i heard about the Dbii F50N-PRO card is very good card, 20 dBm tx-power for 40 Mhz at MCS7 and the receiver sensitivity is -77dBm,but we should achive at least -65 dBm signal strenght with 28-30 dBi dual chain Rocket dish, but i am afraid that it is won't be enough, w...

Trackboy

Hello everybody, 54 km with Sxt, it is definitely impossible to me, anyway i tried to ask in other thread some similar long range links: 22,43 and 30 km but we would like to get 100 Mbit/sec tcp speed in one direction.I have got RB 411 GL it is a powerful device with 680 Mhz CPU and 64 MB Ram, and i...

Trackboy

But it is can damage the card if i good remember, but it is working very well,the signal strenght is about -60dBm,thank you for your help

Trackboy

Hello everybody!In my RB 951 i can not set to the "card-rates" option.This error has appeared:"Could not change Interface wlan1,not supported tx-power mode. I am using ROS 6.7. This device has a strong Wifi, and i need to set the Tx-power about 5 dBm

Trackboy

I read here on this forum 70 Mbit/sec TCP speed with 30 dBi Grid antennas on 11km, 31 km is definitely too much,that's why asked the plan is achiveve the 80 Mbit/sec?Maybe with dual chain antenna and properly CPU performance it is possible.

Trackboy

I can not draw a picture,but here is the scenario: RB 751--------------RB951 they are the OSPF backbone. RB 751 ether1 connected to the ISP:192.168.1.195/24 and the dns is:192.168.1.1 At the moment there is not any area that connected to the backbone. Anyway i took your advice:at the moment i need t...

Trackboy

Hello,so i try out without areas, at the moment the backbone network is:10.10.10.0/24 RB 751:10.10.10.1/24=Ether3, and there is dhcp-client on Ether1 interface=192.168.1.195/24, dns-server is:192.168.1.1 RB 951:10.10.10.2/24=Ether1 On RB 751 enabled: redistribute-connected routes=as-type 1 and redis...

Trackboy

If this is an Point-Point backbone network,why are you using wds?I think you should try out this setup:

A point:mode:bridge
B point:mode:station-bridge

And maybe you should try out with Nv2 as well.

And what's like the line of sight,and the freshnel zone is clear? Because 31 kms is very long range.

Trackboy

So nobody knows why need to NAT the backbone and the area networks?Why not enough just the connected networks?

Trackboy

may i have a question? 80 Mbit/sec or 80 MB/sec? I am very beginner in the networks, but this is interesting for me My friend and me would like to start an wireless ISP, and the distance almost the same in our case as well. The distance is 22,43 km, and we are planning 100/50 Mbit/sec maximum TCP tr...

Trackboy

Yes,the default routes are correct,and my next question is that how should i set the NAT correctly? The internet is working,i can connect from the connected networks for example,with my LG phone I need to redsitribute the default route on my 751,because this is working now as AS router. And all rout...

Trackboy

The default route redistribute has enabled on all devices,but i still can not connect to the internet

At the moment the RB 411U and RB411GL between there is 1 km wireless link,and via this link my friend give me Internet connection,and if i good think this would be an OSPF backbone area,and my home's LAN is for example area1,1 more question:is there more backbone networks in one AS system?

Yes, i know,but my friend RB2011 and the 411U and 411GL are not running the ospf,i am not an expert,i am learning now,how is working in the real life

Trackboy

I have 200mbps real speed link on 35km
i used 36dbi 5Ghz antenna on each side Dual pol MIMO+R52Hnd+RB800

This result is TCP speed?

Trackboy

So what do you think,if the freshnel zone is clear what is the expectable TCP speed with these equipments on 32 km?

Trackboy

The towers are 50 meters

Trackboy

Hello everybody!We are planning an almost 32 km link,and we need some opinion about equipments,we need 50/25 Mbit/sec TCP speed,we are thinking an Rocket Dish 34 dBi,RB800,Dbii 5 Ghz miniPCI,the LOS is enough good

Trackboy

On 2,4 GHZ or 5 ?

Trackboy

Hello,i am interesting about speedtest on 5 km distance,i mean between 2 sxt,i think the 5 km is the maximum distance in normal case if the freshnel is perfect and not too noisy the area, thank you very much for your help,but 50 Mbit/sec TCP speed not bad from this device if it is possible to achiev...

Trackboy

Yes i know,because i think an sxt enough for 1 km,and in normal conditions, it should be work properly,we planning to buy,because the price is good,600 Mhz,64 MB Ram,but it has got just 100 Mbit/sec Ethernet port

I could achieved,only 40 Mbit/sec TCP speed,i tried with FTP,but without Nv2,my Samsung laptop support 150 Mbit/sec with 40 Mhz channel bandwith

Trackboy

Ok,we found the problem,411 GL Ethernet port is not working properly,i have to send back to the store,where i purchased,411 U RB capable of 62/Mbit sec TCP speed with this grid antennas

Trackboy

Ok,seems to be the 80 meters utp cable on ap side between RB2011 and RB 411 GL,not ok,TCP speed only 13-14 Mbit sec,we have to change

So the 411 GL capable of 100 Mbit/sec TCP speed?(50/50 Mbit/sec?)

But with the new Mikrotik mini PCI card the experience is not something good?

Trackboy

Ok,i will test nstreme with UDP,with 20 TCP count the speedtest result is same

Trackboy

Ok,here is the picture,the result is same with 20 TCP count too

Thank you very much for your answers,we are beginner in Mikrotik devices,but this link is properly for learning.

At this moment we don't want to buy another devices,maybe later.We assume the Mikrotik's Bandwith measure is not correct
