Help required

Hi all, I'm looking for someone in the Sydney area who can help me with restructuring and rationalising a medium size corporate network. It will require excellent knowledge of site to site VPN's and tunnels, and excellent subnetting and IP addressing skills as well as good 802.11 skills Currently the client has a large multi-site network which has been built quite poorly with too flat a structure. Essentially the network has been built using small business / home networking knowledge and has grown beyond the confines of what is possible with this type of network hierarchy. Whilst I will be managing the project from an operational standpoint, I need someone who I can bounce technical ideas off and liaise with the client periodically to explain technical why's and how's to their IT department. If I can't find the right person locally, I may also consider paying the right candidate per hour / day for remote assistance with the option to travel when absolutely necessary. Please reply to me directly if you are interested or know someone who may be a good fit. Thanks, *BEN JACKSON* Director *M *0404 924745 *E* ben(a)elogik.com.au *W* elogik.com.au <http://www.elogik.com.au/> <http://www.elogik.com.au>

Hi, Just wondering if anyone knows of any Mikrotik suppliers in Adelaide? Trying to get hands on something today, so can't order it in from the usual interstate suppliers. Thanks, Peter

4G service - backup WAN link
by Vaughan Wickham 11 Apr '18

11 Apr '18

Hi, I've been testing using a 4G service as a backup WAN link in the event that the Main link goes down. I'd chosen ZettaNet. Good pricing. Static IP address. The sites where I will be deploying this solution host servers (mail etc.) and also have IPsec VPN's with other sites; so the static IP address made failover more straightforward. Unfortunately the ZettaNet service has been unavailable a couple of times now over the past few months and they've not been able to provide an explanation so far for the most recent outage. So I'm starting to look around for possible alternative service providers. So far the other service providers I've contacted are only able to provide a dynamic IP address. At the very least this will make DNS updates and IPsec configuration more involved. Questions 1. Has anybody done this where you're hosting internal servers etc. What service provider are you using? Do they provide a static or dynamic IP address? 2. Any comments on using DDNS in A records on DNS and likewise for creating IPsec VPN's. Is it feasible? Thanks Regards, Vaughan

Hi Vaughan, I dont have a setup that I can send a config for handy. But i think i was using 1500. The modem was directly connected to the router. The apn and all 4G services and nat are controlled in the stick nkt the mikrotik as they are a router and basically present an ethernet connection over the usb port.

Huawei E8372
by Vaughan Wickham 29 Mar '18

29 Mar '18

Hello, I've made some progress in troubleshooting my issue. Turns out that the performance issue is not the dongle at all. Am yet to fully resolve (and thus understand) the issue but can advise that the issue may be a routing issue or some sort of network configuration issue. The scenario that I have is as follows: User PC's Main router (main link down) 2nd router (use backup link) 4G dongle I need two routers, because the main router doesn't have a USB port, and I want to add a backup link without discarding the existing equipment. What I have just tried is connecting a PC directly to the 2nd router and testing the 4G dongle from there. When I do that the performance is the same as when the dongle is connected to a PC. So the issue has to do with the routing between the Mikrotiks - or something like that anyway. The issue is not the 4G dongle itself. Appreciate the feedback from those who responded. Thanks Regards, Vaughan

Huawei E8372
by Vaughan Wickham 28 Mar '18

28 Mar '18

Hello, I've been testing an E8372 USB 4G dongle with an RB951Ui-2HnD router According to https://wiki.mikrotik.com/wiki/Manual:Peripherals the E8372 works My experience has been that it "works" to some degree. Connecting to some Web sites (e.g. www.smh.com.au ) works consistently, yet connecting to other Web sites (e.g. any speedtest site does not work at all). In contrast, when the dongle is connected to a USB3 port on a Windows PC, the performance of the dongle is perfect. Also accessing the Web portal of the dongle seems quicker when the dongle is attached to the Windows computer versus the Mikrotik. I'm pursuing a couple of avenues regarding troubleshooting - The Mikrotik has a standard USB2 port and this may not be supplying the required power for the dongle o I have ordered a USB2 hub with an external power adapter which will supply the power requirements of the E8372 (5V and 750mA). So will test this soon. - I've not been able to configure the APN for the 4G service provider in the LTE properties. There is no error, but the APN is not saved. I am able to save the APN in the 4G dongle's own firmware/web portal, but I'm not sure whether this is used when the traffic is traversing the LTE link of the Mikrotik So the questions that I have are: 1. Is anyone else using an E8372 with a Mikrotik? a. If so, what is your config? b. Are you using a powered hub c. Did you need to save the APN in the LTE properties? 2. Is anyone using some other 4G USB hub with a Mikrotik? Thank you Regards, Vaughan

Telstra Frontier Modem/Router with Failover into MK Router
by Matt Hall 27 Mar '18

27 Mar '18

Hi Everyone, The new Frontier router/modem (Technicolour DJN2130) from Telstra has 4G failover built in but if you bridge it failover doesn’t work. I’ve tested this by unplugging the WAN port from the accompanying cable modem (Netgear CM450-TLAUS) and also by unscrewing the fibre cable. 4G won’t kick in. If you do the same with the factory settings config, 4G kicks in. I’d like to route and run Wireless from my MK router but am unsure about a few things. Basically I’d like the Frontier to do as little as possible. So far I would do this on the Frontier: Under WAN Services 1. Turn off NAT-PNP 2. Turn of UpnP? 3. Turn off secure mode? (not sure what that is). 4. Turn off Wi-Fi 5. Turn of DHCP Server 6. How should I setup the Firewall? I can’t turn it off completely it seems. Firewall settings are: Low mode, the firewall will allow all outbound connections. It will reject unknown incoming connections but acknowledge the presence of the gateway. Normal mode, the firewall will allow all outbount connections. It will silently drop unknown incoming connections. High mode, the firewall will allow outgoing connections to the following services: HTTP, HTTPS, SMTP, POP3, IMAP, SSH. It will silently drop unknown incoming connections. User mode, you can configure each individual rule of the firewall as well as the default behaviour. User defined options are: Answer Internet ping On/off Outgoing default policy: ACCEPT/DROP/REJECT The outgoing policy defines what is done with packets coming from the LAN devices toward the internet. Setting it to REJECT or DROP will forbid any internet traffic from the LAN unless explicitely allowed by a firewall rule. Incoming default policy: DROP/REJECT The incoming policy defines what is done with packets destined to the gateway. They can be either REJECTED (the gateway will notify the sender they were rejected) or DROPPED (the gateway will silently discard those packets). Then to manually add a new rule options are: 1. Action: ACCEPT/DROP/REJECT 2. Protocol: TCP, UPD, TCP/UDP, UDP Lite, ICMP, ESP, AH, SCTP, all 3. Src IP 4. Src port 5. Dst IP 6. Dst port Then firewall rules for IPv6 follows the same protocol. Thankyou, Matt Hall Sydney

Re: [MT-AU Public] Mikrotik - Wireless Issue on hAP and hAP ac lite

As an aside, have you seen your non-Apple clients maxing out at 54Mbit TX rate on 2.4GHz as per this thread? https://forum.mikrotik.com/viewtopic.php?f=7&t=102908 At my place Apple devices are fine but anything Android - including out late model Samsung phones refuse to go above 54Mbit TX. I am surprised this isn't resolved and seems to be in the Too Hard basket for Mikrotik! This is a problem anywhere you put in loads of Mikrotik devices.
