@CharlesIsWorkin  - One of the community member gave me a suggestion to upgrade the downlink Meraki switches to the latest beta version 14.21 which seems to have reduced some issues for my team, however, we are still testing the 15.42.1 on one network. ... View more

@PhilipDAth  - Unfortunately, because of all our client VPN issues, we are moving slowly to F5 VPN now. The main purpose of the 15.x upgrade was IKEv2 since it was a blocker for many of our cloud integrations. And thats a great tip to use the ISP directly on the WAN port, which we have setup in the same way. ... View more

@cmr  - Yeah, no luck after 14.21 upgrade, and I checked we are not using aggression.  Well, now my Client VPN disconnects automatically in few seconds. But thanks for the advise. ... View more

@cmr - Ah! maybe that could be it. We are running 12.28 on both switches, however there was no mention of switch OS in the 15.42.1 release document for compatibility.   So you saying the "beta" OS 14.21 is good to upgrade? ... View more

@cmr  - We have a very simple hub setup on 3 DC , however we are not using VPN concentrator, we are using Routed mode. Two pairs have single WAN connection and the other has 2 WAN connections.    When I upgraded one MX to 15.42.1/15.42  it had random packet loss drops etc. to all the other MXs from the "Client VPN"   Client VPN is the key issue for us. That is when I see the 4 behaviours I mentioned before. But looks like no one is nearly using Meraki client VPN as we do, so it's very uncommon for others. ... View more

@cmr  - Thanks for your reply. Here is our simple infrastructure.   ISP -> MX250 standalone -> MS350-48 (acting as core) -> MS350-48FP -> APs and Clients   The switches are single and MX is also single at this point. ... View more

@cmr  - I totally agree and respect it. However, it's not frustration but its honest awareness that I wanted to bring out amongst all the Meraki users that we have been dealing from past few months, it's not about a day or two. Also, the site to site that I am mentioning is Meraki Site to site peer, not the Non-Meraki peers which need the local IDs  😊   ... View more

@cmr  - So we have few locations where we are using Meraki Cores, and this particular upgrade was done where we are using MX for routing. ... View more

I am specifically posting my experience with Meraki Support and Meraki latest "Stable" release 15.42.1    I upgraded our "X network" MX box on this sunday at 4.30pm PST.   To start with, it's been a very poor code quality since Meraki released 15.42 and 15.42.1. Taking some packet captures, revealed that there is connectivity and routing issues between Site-to-Site Meraki peers, so while on one location client VPN, you cannot access the resources of the another location, there are intermittent packet loss. Since the same day we started experiencing the connectivity issues in our Client VPN. These are the behaviours. 1). I connect to our "X network" client VPN on Meraki. Connects fine. Then within one minute the VPN disconnects automatically with no error message nothing. 2). I connect to our "X network" client VPN. Connects fine. No internet works on the VPN, internal and external. I can see packets going out, but no return traffic. 3). I connect to our "X network" client VPN. Connects fine. Internal traffic does not work, external traffic works. 4). I try to connect to our "X network" client VPN. It gives me Authentication failed for the same exact credentials that are saved in my VPN profile which was previously authenticating without any issues.   I have downgraded the "X network" MX box on 14.53, and now everything works fine. This happened on both 15.42 and 15.42.1.   Here is a sneak peak of other blogs of users facing similar issues - https://www.reddit.com/r/meraki/comments/n5hygl/mx_15421_breaks_routing_somehow/   Last but not the least - I have been on support hotline for about 40 Mins now, but no takers of my call. Kudos! ... View more
