I'm not asking for them to add any features. I'm just asking them to fix a bug in a feature they have already chosen to deliver. It's not unreasonable to want them to do that in a timely manner. It wouldn't be correct to add the rules to the template because the port forwards are different at each site.

I have several networks set up using templates. And some sites have needs for port forwarding from the public IP address. Rules are configured in Security & SD-WAN > Firewall in the Forwarding rules overrides section. Example: This works once when the rules are initially added. If I try to make any changes at all, though, saving fails with a generic "Failed to Save" error. If I want to change the description of a rule, save fails. If I want to add a rule, save fails. If I accidentally left the protocol at UDP and try to change it to TCP, save fails. I opened a support case Feb 17 2020. To get me through the immediate need, the work-around was eventually discovered that I need to delete all of the port forwarding rules and re-enter them all by hand. If I make a mistake during re-entry, I need to restart and delete everything again. That was acceptable for a quick fix, but it's been almost a year now and the bug has not been fixed. There is no indication that the issue is limited to me. It probably impacts other customers that use templates and port forward overrides. While I don't know the full details, I am a software developer myself and this seems like it could be fixed by a junior developer within a few hours. When I ask for an update of the case status, I'm told no update exists. If I request an escalation, the request is denied. I asked my VAR for assistance and he told me he's not getting responses. (Oddly enough, he got a response when I asked for a quote to buy an additional license.) This is not the kind of support experience I expected from an enterprise network vendor. I expected that bug reports would be triaged and worked into the development schedule. There is a difference between prioritizing something and completely ignoring it. I read a Veeam post about how their support system has an automatic escalation mechanism if a case has been open for too long. With Meraki, there isn't even a way to manually escalate a case.

Meraki DHCP is set to provide the domain suffix (option 15). But none of the Ricoh printers are using DHCP. I also noticed that some of the printers that were successfully scanning to email didn't have the correct value in the field. It seems just being blank was a problem.

It appears that the problem has been resolved. All of the Ricoh printers are configured with static IPs in their settings. In Configuration > IPv4 settings, there is an option for Domain Name. The Ricohs that weren't working either had it set to DHCP or had it set to Specfiy with a blank value. After I entered a value and saved, scan to email started working. Some of these printers had been set for this like years without problems. Part of me still doesn't believe this fixed things (because why would it?) But it's been several days and none of the users have reported problems since they were informed scan to email was working. Thanks for all the suggestions and trying to help me resolve this. I appreciate it. This was a great experience.

Not that I can tell. And it gets weirder. Templates are being used as much as possible. There are 3 sites on one template communicating that scan to email is not working, and 1 on the same template that is scanning fine every day.

The connections are via AutoVPN. Some of the circuits may be MPLS, but when they are there is still an AutoVPN tunnel on top of it.

I'm part of a team involved in a WAN upgrade project. We've been replacing EOL Cisco routers with Meraki MX67s. Auto-VPN is used to connect the sites to a central hub. There is an MX100 at the hub. At multiple locations, immediately after installing the MX67, Ricoh scan to email started to fail. However, at some other locations, it continued to work. Technicians have done an A:B comparison of the Ricoh settings between the sites that work and the sites that don't and haven't found any obvious differences. The Ricoh scan settings are configured to use an internal email server located at the hub site connecting via plain non-SSL SMTP over port 25. The data only has to travel over the site-to-site VPN tunnel. It never touches the internet. The Ricoh logs have generic errors that you'll find years worth of posts about in an internet search. Many of those have to do with authentication problems with Office 365 or Google G-Suite. That's not the case here. The email server is happy to accept unencrypted, unauthenticated communication. Here is an example from the Ricoh log: #[dcs_nas(104)]20/09/21 09:31:04 SMTPC: connection closed. (501) ERR:
#[dcs_nas(104)]20/09/21 09:31:04 SMTPC: connection closed. (701) ERR:

Acking message as failed." So the Exchange server is failing the message after it receives what it considers junk. Since this is all internal traffic, Meraki Advanced Malware Protection (AMP) shouldn't be involved, but could one of the Merakis be altering the traffic? I found a suggestion online to disable "SMTP inspection" if using a Cisco ASA. Obviously, nothing like that is present in the Meraki cloud controller, but is there a similar feature running on a Meraki MX? I did try opening a support case with Meraki, and the support rep did packet logging while an end user ran some scans. The technician didn't see anything of note. But the fact is that at some locations before Meraki MX67, scan to email worked. And after it didn't. Any suggestions you might have would be greatly appreciated.

The solution I had posted in November 2019 has been working. The short of it is that you create a static route on the hub MX for the internet addresses you'd like to through the VPN tunnel. For next hop, you put the hub MX IP. This would create a routing loop. So, you want to uncheck the Enabled box. This will cause the route to be advertised through the VPN tunnel by the hub MX. The spoke MX will see the route advertised by the hub MX and send the traffic through the VPN tunnel. Then when it arrives, the hub MX will send it out the WAN interface. One would expect the hub MX to stop advertising routes that have been disabled, but that hasn't happened in the 3 months since I set this up. I opened a support case to get clarification, since the setup seems a bit suspect. The support rep communicated with the development team and relayed the following: 1. This is not intended behavior. While the team doesn't have any plans to actively change how it is working, a future fix for an unrelated issue could have the side effect of closing up the loophole. So, it's use at your own risk. 2. The team does plan to implement a supported way to accomplish selective routing of internet traffic through VPN tunnels. My plan is to ride out the work-around until the supported solution is available. The worst that can happen is that the work-around stops working before the official solution is available and I'm back to where I started. But right now things are working exactly as I wanted, and I didn't have to buy any extra equipment. If you are doing pre-purchase research, don't base your decision on this work-around, because it is unsupported and can disappear. But if you've already got Meraki gear running, you don't have much to lose by trying it out.

This has been working great. I used this technique to configure VOIP traffic to go through the VPN tunnel out a reliable data center fiber connection. A colleague and I tested a phone call between a VOIP phone and a cell phone. I unplugged the WAN1 link and the call continued. I reconnected WAN1 and unplugged WAN2, and the call continued. This is something I did not think was possible with Meraki. We did notice brief interruptions due to lost packets. But it was much better than expected. I think the Meraki team is missing out on an opportunity here. The Velo Cloud sales reps kept telling us how VOIP calls don't drop with Velo Cloud, but they do with Meraki. I was on a call with Meraki sales reps telling them I didn't think Meraki was "real SD-WAN", and they had no response. And that's the sentiment I got from third party sales reps that sell both. They told me if I wanted true SD-WAN, to get VeloCloud. If I wanted a more reasonably-priced solution, get Meraki. One VeloCloud sales rep used the phrase "you get what you pay for". However, it is possible with Meraki to do a spoke failover without VOIP calls dropping. If they wanted to, the Meraki team could implement packet duplication and jitter protection, and compete with the VeloCloud VOIP feature set.

I've been struggling with this for the past few days. The company has VOIP telephone service. Each branch has two WAN uplinks. If an uplink goes down, then the phone calls will drop when the branch MX switches to the second uplink. If I can route the VOIP traffic to the MX at the data center, then the branch uplinks can switch without the VOIP service seeing a change in the IP address. I can also simplify IP whitelisting with 3rd party services if I can backhaul all of the traffic to those services through the hub WAN IP address. But I can't send all of the branch internet traffic to the hub because that would kill the hub's uplink bandwidth. I opened a support case and the rep responded it is not possible to set this up. I called in and the second rep told me if I can get the hub MX to advertise the route, the branch MX will send the traffic over the VPN tunnel. When I asked how to do that, he told me to put a static route into the hub MX with the IP of interest as a /32 subnet and the MX IP as the next hop. I tried that, but the traffic got into a routing loop. One would expect this to happen, but I have seen the Meraki dashboard have special support to "do what I mean" with some things like this. To resolve the routing loop, I disabled the static route. Then something amazing happened. Things started operating exactly as I wanted. The hub MX continued to advertise the route to the branch MX, and the branch MX happily sent it the traffic, but when the traffic got to the hub, the hub MX sent it out the WAN link. Perfect! So, this is great. But I am worried that this behavior would be considered a bug that will eventually be "fixed". If I were a programmer of the MX firmware, I would not advertise static routes that are disabled. The point of disabling something is to completely remove it from use without losing the information of what used be active.
