The downgrade ended up working. Everything is up and running. I did have to do some micromanaging on the servers ... i.e. backtrack the troubleshooting steps that were done before the ticket was escalated to me. Therefore, I don't know if adjusting the traffic shaping rules to normal actually worked or not. But, it is all fixed now with rolling back the update.  ... View more

And everything up and working. The downgrade worked! ... View more

I might have lied. This might be working with the revert. Reverting all of the troubleshooting on the test pc before this got to the network engineer...... 😆 ... View more

Same issue going down to 18.107.2 per meraki support request. I am trying to see if there is anything I can look at prior to calling meraki with my ticket number again. Trying some basics right now just to reset network connections for some of the test machines.    It is very strange. The issue started the same morning that the device was updated to 18.211 (we actually have two organizations that updated). We first noticed an issue when connecting to SMB shares. Now the shares sit on one vlan and end users trying to access come from another. So I would think that is the cross vlan traffic we was mentioned as dropping. Am I correct on that assumption? We did notice later that RDP was dropping between vlans, etc. ... View more

It looks like MX86 isn't part of the issues with AutoVPN. MX75, 85, 95, 105,250, and 450 are the ones having issues.  ... View more

Going to find out in the morning if our downgrade solves the issue. We updated to MX18.211 the same morning issues started being reporting (just one business day ago). It appears that some cross vlan traffic is dropping. The results almost seem random. For instance, some PCs can reach certain file shares, others can't. Some resolve DNS, other's don't.    I did try changing our traffic shaping policies to normal (a few were at high, others were at low). So far, this has not resolved the issue, but I also haven't had the downtime to reboot our network stack. Here's to hoping the firmware revert works...  ... View more

UPDATE: I tried to revert traffic shaping rules to normal to see if issue resolves. No progress yet. I don't have a downtime window to reboot appliances right now, so I don't know if a reboot would help with the workaround. I will most likely find out post upgrade (in the AM) if this was the issue.    I did notice that the mx updated to 18.211 the same morning issues occurred.  ... View more

I have my downgrade scheduled in the am so I will follow up and let everyone know if it worked, but we started experiencing what seemed like intermittent route drops in inter vlan routing. We have been ripping out hair out ever it. The client does have traffic shaping going on. I will find out if rolling back worked in the morning. ... View more

Replying to my own comment! So, we downgraded to 17.10.4 on both of our devices that had the auto vpn and everything is working again. It looks like there are still issues (similar to previous stable candidate) with auto vpn latency and drops. We are locking in the 17.10.4 until there is a new stable version to try.  ... View more

I was looking at the forum for MX Version 18.107 . In it, some users seem to have had issues with Auto VPN speeds. Recently, we upgraded to 18.107.2 and I am seeing autovpn speed issues. Has anyone else been experiencing this on 18.107.2 ?  ... View more

Completely avoiding this update. We have had two issues with two separate clients. One on ms320 other on ms350. MS320 it completely broke poe. Ms350 it completely broke stacking. After downgrading both from 15.20 back to 14.33.1, SFP is now broken. I know it says stable release candidate-- I'd suspect it never becomes an actual stable release.  ... View more
