Re: Setting up RDP via Dashboard on EdgeRouter X

I do not see what is stopping you from using RDP right now. It seems you are on a LAN and want to RDP to a server what is also on your LAN. Perhaps that server has Firewall turned on that is blocking RDP traffic or you didn't enable Remote Desktop on that server. What OS is the server running?

The server is running Ubuntu 16.04 and I set up the iptables to allow all incoming and outgoing traffic, so there aren't any configurations there that should be stopping me. As I mentioned in the beginning, i have no problems with ssh but I can't rdp into the server with any of the various tools I have tried. I'm looking at the advanced settings for the pocket wifi connection now...

Re: Support for g.fast SPF

That does not look to bad, I get the following with a 3Com RJ45 SFP which works just fine

 

connector=Unknown
vendor=AGILENT         
oui=00-30-D3
part=QBCU-5799R      
rev=    
serial=L1WP6Z0709310   
date=060620

 

It could be that it needs the port speed needs setting manually. What does the following show?

 

show interfaces ethernet eth5 physical

If you forcing the interface to 1Gb/s with the following and then replug the SFP does it work?

 

configure
set interfaces ethernet eth5 speed 1000

VOIP issues

We use VoIP within one of our satellite offices that has a point to point back to the main campus to communicate with the phone system. We have several customers setup this way without issue but this particular office has severe issues. Most phone calls are static and you cant really here the other person talking. I setup QoS but it doesnt seem to help much. Can someone chech my config and make sure it looks right? TIA.

Re: Use EdgeRouter 4 SFP for main LAN

I do exactly this. I upgraded to an ER4 from an ERX-SFP so that I could use gigabit internet. Since the ERX-SFP has POE, I set it up like a switch (via the wizard), connected ER4 SFP to ERX SFP via a cable I bought on Amazon, and then the ERX SFP powers 3 Unifi APs and then goes to a 16 port managed switch for the rest of the network.

Okay, I am in business. After your mention of "enable Remote Desktop" on the server I edited Desktop sharing preferences on the server and was able to access the server using Remmina over VNC. It isn't working for Guacamole but I can play around with that some more. Many thanks for the help!!

EdgeRouter X Skype for Business desktop sharing does not work

$

Hi !

This is my first post, so I'm new to Ubiquiti with EdgeRouter X, but I really like it and its seems quite a fast and powerful device.

Now to my problem, since I switch to ER X I have problem with sharing or see someone desktop in my Skype for Business sessions. Voice is working no problem.

There is page on MS site:

https://docs.microsoft.com/en-us/office365/enterprise/urls-and-ip-address-ranges?redirectSourcePath=%252fen-us%252farticle%252fOffice-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2#bkmk_teams

That details what ports need to be open.

I try this with Port Fowarding feature but it did not have any impact on this.

 

Is there some simpe way I could try to check what is the problem ? Or simple way I can create some rule to treat Skype traffic in different way ?

 

My configuration is standard eth4 as DHCP WAN and rest of the ports as switch0. I have upnp2 enabled as well.

 

 

Thanks for any support

Are you hosting Skype for Business server locally or are you just using a client on your PC? If the latter, no ports need to be opened on a router at all for it to work properly.

Hello,

Thanks for your feedback. I'm going to study that and you'll have an answer to describe what I did.

Thank you for the suggestions. I did run tcpdump and can see a striking difference on the ER-X when the problem is absent vs. present. 

 

I've attached two tcpdump output files - one for when the problem is present and one right after an ER-X reboot when the problem is not present. The tablet is 192.168.1.39. The TCP flag is always 'S' when the problem is present and always 'P' or 'P.' when absent.

I'm inluding two screen shots here: a shot of a 'Trace. from the ERX Trace tool to 1.1.1.1 (the whole thing fitinto the tiny trace window of the ERX) and a shot of the ERX Dashboard that shows eth0 and its assignment to a DHCP controlled region of IP address space.  If I mess with eth0 in a way that makes it no longer a DHCP client, I'll break my internet hookup, won't I?

The only unique element I can think of is the problem device is the only Android device. While it is an "always WiFi" device, so too are some of the PCs which share the same network, and access the same mail servers without issue. Chrome and other internet accessing programs (VNC, Feedly, autoTrader, OneNote, etc.) all seem to operate properly.

Re: A simple question

Your explanation is understood.  I don't see why creating 192.168.2.0/23 wouldn't solve the problem too.  Is anything on the eth0 port with a private IP address blocked?  Or does a packet for a private subnet never get emitted on eth0 in the first place?  Forgive me me if I'm stuck in layer 2 thinking but I'm a circuit and locic desiger.

 

I suppose it's academic but now I have make my 192.168.3.X a VLAN.  I have no idea how.

Seems like the IMAP server in 2nd case is no longer answering.

S means SYN, it's the first packet of a new connection.

 

You could try to sniff on WAN interface as well, to see if remote server answers.

sudo tcpdump -i eth0 -n tcp port 993

Also worth trying is increasing TCP keep-a-live time:

configure
set system conntrack timeout tcp established 28800

save;exit

You might want to make sure that you are actually pulling a /56 from google.  I can only get a /64 to work despite their claims.

Re: ER-X installation problem

Hello! This time in the ER-X Basic setup wizard I chose the Static IP as Jonatha suggested:

 

Address 192.168.0.1/24

Gateway:192.168.0.1

DNS server: 4.2.2.2

 

I rebooted the ER-X and did the usuall routines. Executing ipconfig tells me:

 

Connection-specific DNS Suffix:

IPv4 Address: 192.168.1.38

Subnet mask: 255.255.255.0

Default Gateway: 192.168.1.1

 

To my surprice I was able to connect to the ER-X through 192.168.1.1 while the PC was connected into eth1. The reason was that now there was two Internet ports, preferred eth0 and secondary eth1 which is used if the first one fails for some reason.

 

Now Windows debugging told me that the DNS-server is 'maybe' not available. The Internet connection was not working. Still both 192.168.0.1 and 192.168.1.1 answer perfectly to pinging.

 

Well this setup didn't fly well eighter. So back to the beginning, plugging the PC into eth0 and typing 192.168.1.1 into the browser's address field. The connection timed out. So I had to reset the ER-X as I usually have to in order to reconnect to the ER-X after running a setup wizard.

 

I'll have to do some reading...
