Sounds like a Hairpin NAT problem.

Have a search for something like "mikrotik hairpin nat".

There is also a presentation in the Thailand MUM recently. Have a look at mum.mikrotik.com, archive, Thailand

rjscomms

Thank you 43North.

I had a problem when my hosting company changed a bunch of stuff and I noticed I was not getting any notifications anymore.

This appears to work.

rjscomms

out of interest, how are you connecting to your ISP?

The ping times to your gateway are 0ms...very quick!

Are you sure the gateway IP is correct?

rjscomms

Nice work.

I just tried it and it works fine.

rjscomms

Hi again,

I understand now what you really wanted.

I have tried the code you suggested but it still requires the login. I think here the MAC field just locks it to one device.

Sorry, but not sure how to help. If I find out something, I'll post back.

rjscomms

Hello,

can you ping your gateway?

rjscomms

Hello,

try this:

/ip hotspot ip-binding add mac-address=XX:B8:37:BE:19:XX type=bypassed

They should be authenticated without asking for username/password.

rjscomms

Did you have a look in the ARP table after the scan?

If I do it, I see the interface in the ARP table.

Perhaps I missed what you really wish to see.

rjscomms

Tools > IP Scan

Have you tried that?

rjscomms

Hello,

have a look at Tools -> Torch. Select the appropriate interface and click on start.

Also, there is Tools -> Packet Sniffer.

Have a look under DHCP server -> leases to find out the IP address, assuming it gets it via DHCP of course.

Enjoy.

rjscomms

I know this is not exactly what you want, but there is

/system note

where you can type a message as you describe. It is for a terminal session though.....make the admins login with ssh or similar

rjscomms

painful as it may be, perhaps a reset of the configuration and start again.

rjscomms

is the protocol definitely tcp?

rjscomms

Hello,

I'm not an expert but could you humour me and add dst-address=your_WAN_IP in the NAT rule.

I had a funny case where I had what you had, but it was giving me strange results. Putting in the dst-address worked for me at least.

If they are using wireless, you could create an access list entry on the access point and configure the restricted times there. You just need to find out their MAC addresses.

The CRS series is a Cloud Router Switch with a quite different switch chip. It is intended to be more like a traditional switch.

rjscomms

where Office is the name of the interface of your LAN.

Have you seen this page? : http://wiki.mikrotik.com/wiki/Manual:Interface/L2TP

Hope it helps.

Apologies, it should be Wan-1-out as bartoszp stated, since that is your pppoe interface name.

rjscomms

Hello,

what is the brand of DC converter?

Remember that the earlier DC converters (48VDC-24VDC) that Mikrotik made had a 100Mbps port.

I believe the newer one (if available) has a 1000Mbps port.

rjscomms

Hello,

if you are in winbox, click on "New Terminal".

This will open up a terminal window into which you can type the commands you have shown.

You can try the same in webfig but sometimes the terminal is blocked by your browser. Better to use winbox.

rjscomms

Hello,

I am no expert here but I believe that creating a bridge and using ports will use the CPU.

Using your second method means using the switch chip which should be faster as it does not use the CPU.

This is described somewhere on the wiki.

Regards, Dave.

rjscomms

Hello,

you have no action statement in your NAT rule.

Have a look at this site for example.

http://www.icafemenu.com/how-to-port-fo ... router.htm

Assign IP addresses etc to the bridge only. Ports in the bridge lose their identity when they are part of a bridge.

Have you created a bridge and then added ether port and wireless port to the bridge?

Hi,

I know on the CRS226 that the left SFP+ module (as you look at the front) is capable of using an SFP module. Not sure about any other models.

There is a MUM presentation on this somewhere.

rjscomms

Howdy,

my interpretation is that it is single mode fibre but ONE fibre, not two as required for transmit/receive.

When we run fibre we usually get 6 core or more (three pairs) since that gives you extra in case.

Hi zap,

rjscomms

Hi Zap,

Thanks, Dave.

rjscomms

I'm glad it worked.

I am actually going to install a mesh setup tomorrow using four 951Ui. I will be using HWMP+ and WDS.

It automatically sets up the other units.

Anyway I look forward to your writeup.

rjscomms

I'm not an expert on this but I think you need to set it up on each device. I believe the syntax shown above is just to setup a static ads link rather than a dynamic one.

Maybe you can use dynamic mesh here to make things easy.

rjscomms

Hello plisken, I was just reading through the wiki page for HWMP+ and came across the syntax you describe. In the example setup on the HWMP+ page, they describe the setup as follows # a static WDS interface for each AP you want to connect to /interface wireless wds add disabled=no master-interface=w...

rjscomms

Glad it worked for you.

I think they have not updated the wiki page for l2tp/ipsec because the proxy-arp feature is not directly related to l2tp/ipsec as such.

rjscomms

Hello,

just a quick thought, do you have proxy-arp enabled on the interface facing your internal network?

Have a look at the wiki page for PPTP and it describes it there. I believe it is still applicable in your case.

Hi there,

It certainly can feed a LAN switch.

I use a 2011UAS and the SFP port for this exact reason because the distance is too great for cat5e.

I have used the Mikrotik SFP modules in the 2011UAS and also in the Edgecore switch I use with no problems.

Hi again, Sorry but I am no expert on this. I guess trying to scan a whole webpage for the content you want to filter would be expensive in terms of resources so I am not sure if it is possible. Regarding using arabic, I am afraid I do not know about that. I guess you could just try it out. Cheers.

rjscomms

Hello,

Within ip firewall filter, there is a content field. In that field you can enter the text you want to filter against.

In the wiki pages, there are some examples.

Beware that you might filter the wrong thing if you are not careful.

Hope that gets you started.

rjscomms

Hello,

You could use a normal wireless lan for one network and a virtual access point for the other network.

but do not do it on a working interface otherwise you may disconnect yourself

You should see packets counting.

Then do this

/interface wireless sniffer> packet pr

to see the packet info.

rjscomms

Howdy,

I believe ports 1-5 are in one switch group and 6-10 are in another. To use ports 3-10, you could configure ports 3-5 to one switch group, ports 6-10 in another, then bridge those master ports together.

But then a dedicated switch is probably better...after all the RB1100AHx2 is a router

rjscomms

Hi Trackboy,
