Further test to confirm MA-CBL can be used for 1G / 10G mixed.    MS225-48FP SFP+ port >>> MA-CBL-3M >>> MS220-8P SFP port came up once I changed the link negotiation to 1Gbps  ... View more

Hi Baka,  I understand there is a official datasheet however, I have had mixed results in the past and have had the MA-CBLs come up at 1Gbps line rate.    Image attached, I have a MS210-48LP uplinked via its SFP port using MA-CBL-TA-1M into a MS410-16 SFP port. The interface is up and the speed negotiated at 1Gbps     ... View more

Hi SCC,   There is probably a few ways to do this.   As the Nighthawk is essentially a router you could setup a separate VLAN just for your phone(s) to communicate to it as their default gateway rather than the MX68.   ... View more

Hi Silas1066,    The other option you have is to request Meraki support upgrade that network and device to 15.9 No-NAT beta release. You then have the option to disable NAT on the interface that is facing your MPLS Network.    Regards, Ben ... View more

+1 on those two wishes. I've put these in before to Meraki ... View more

Hi Bkeys, Yes you'll need to call Meraki support. Make sure you ask them to update these following areas 1. Update the MX to No-Nat 15.x 2. Update the Network dashboard to see and configure No-Nat 3. Apply the No-Nat feature to the interfaces (they need to do this initially) If you have trouble let me know. Not all of support are aware on how to successfully implement this No-Nat feature ...

@ccnewmeraki Hi Christian, Support eventually figured it out with the assistance of your ticket number. My whole Organisation dashboard was missing a setting that was necessary for the changes to take affect. Once I then rebooted the MX appliance the NO NAT finally worked as expected and required.   The No NAT has addressed some issues that we were experiencing and believed was caused by NAT.   We still have one major issue which we are still trying to work out with Meraki support.   Has anyone else come across issues with MX routers not handling fragmented UDP packets correctly? Cisco Traditional ISR's allow up to 24 fragments per packet while a Meraki MX64 only allows up to 4, which is still causing issues with our VOIP handsets.   Thanks, Ben ... View more

Hi Christian,   I've sent you a PM, if you could send me your ticket number to pass onto support that would be great!   Thanks, Ben   ... View more

Hi ccnewmeraki,   Thank you for your extensive reply. I'll get back in touch with Support and hope we can get this sorted out.    Regards, Ben   ... View more

Hi ccnewmeraki,   Thanks for the update and advice on how you have successfully enabled the NO-NAT feature.    Support have advised me there is no modification to the inbound rule, yet the NO-NAT mode still is not working for me. I have quoted word for word what you supplied in your last post. Apparently as well the NO-NAT mode does not work on VLAN based exceptions and can only be done per interface. Have you had this issue?   Regards, Ben ... View more

Hi Owen,   Same problem here. What I've had to do is create a 1:1NAT rule for external hosts to be able to get to internal hosts.    Okay for a dozen or so hosts in some of the small deployments that I have but I'm not looking forward to filling out a whole /24 for a voice network!    Support are working on 15.4 with me and my situations, they've explained that they're are continuing to develop this new no-nat mode in the labs.   Regards, Ben   ...

@AdamS  ...Jaw drop    I'm pretty sure I get the concept of the Beta mode with no NAT mode.    Could you please elaborate a little further for me?    We have dozens of sites with dedicated MPLS only, the data VLAN is Auto-VPN'd back to the data centre concentrator while the voice VLAN is nat'd whereby the MPLS provider then takes the voice traffic out to their media and SBC gateways. Does this mean I can get a private /24 routed to down the link and not nat'd to the handsets?      ... View more

Hi Philip,   Interesting idea, I might look into dual carrier diversity rather than 4G for the data centre.    It sounds like Meraki are doing work around the MPLS situations and may have some nice features to accommodate.    Thanks! ... View more
