RBLtAP-2HnD kit with "R11e-LTE6" Phone gives me up to 370/24 Mbps ( Galaxy S8 - 2017 ) Routerboard 38/16 Mbps, and yes they confirmed there is bug with modem firmware, but no respond from support when they release update. It will be nice to first make your modem work properly Same problem here!

- HW: 1GbE port
- HW: RBLGHR with improved antenna and with purchase option "empty PCI slot"
- SW: GUI support for control of Cell-Locking, CA, etc.
- SW: Scanner functionality optimized for connection characteristics.

Not sure if I could help with this. But when you have a lot of data, its sometime better to do a summary indexes that is based of for example 1 hour reports. Then you get less data to search trough.I do recommend that you start a thread about your problem over here: https://answers.splunk.com/index...

We operate LTE as backup in some rural areas and always force the CPE to utilize 800/900 Mhz since the higher frequency bands are much to sensitive for trees, rain and snow in longer distances and when you don't have LIS.

dead peer detection should be enabled by default (interval 120 tries 5)

Don't do it that way! Delete the IPsec Peer and Policy you have now, create a GRE interface, specify source and destination address (the public IPs of the routers) and set an IPsec secret. Then put a /30 network on the GRE interfaces (e.g. 10.0.0.1/30 and 10.0.0.2/30) and route the networks on each...

Sorry for the delay- I was a bit more than just busy. So I tested everything again and it is definitely working and I am passing traffic through the tunnel.

Larsa

Packet flow diagram will illustrate why you need route for destination even if gateway of that route will not be used: https://wiki.mikrotik.com/images/6/68/IpsecFlow.png So if I understand it correcly, then the only way to set the outbound address of the tunnel is to control pref-src by for exampl...

And I second the proposal for GRE/IPsec

I concur, but even if you put GRE/L2PT on top of the tunnel you'll probably get the same issue with the outbound address as before...

Larsa

Sorry, but I forgot to mention that the tunnel gets established but cannot pass any packets since the remote peer gets pref-source from the sending side as the return address i.e outbound address = pref-source. If possible, please enable logging for protocol 50 (ESP) and check for the same behavior....

Larsa

Not back in the office, but I have an idea to check in the mean time: Do you have any masquerade rules configured in /ip firewall nat? I could bet you have. Masquerade always uses the lowest address on the interface, no matter what is defined beforehand. Convert this rule to src-nat (and to-address...

I have a couple of IPsec tunnels running here with multiple WAN addresses and they're running just fine as expected... -Chris Our tu...

Larsa

You need to set the "prefered source" on the route - it will set the outbound router ip address. Ok, so if I understand you correctly pref-source is the only way you can control the outbound address for a IPsec tunnel. So in case you have a "/29" subnet defined for your WAN, then you need to assign...

Larsa

Instead of a direct IPsec tunnel, use GRE over IPsec or L2TP over IPsec to establish a tunnel, and route your LAN traffic via that tunnel. That will end all your problems with NAT avoidance etc. Hi!

I recommend you skip the router and hook up a PC directly to the WAN port where you have your mail server. If you are using Windows download nc.exe and then run an outbound test using: C:\> nc -v smtp.gmail.com 25 gmail-smtp-msa.l.google.com [64.233.161.108] 25 (smtp) open 220 smtp.gmail.com ESMTP w...

That's easier then. Use AES over DES. 3DES is notoriously slow in software, and it's unlikely to be optimized in hardware.
