Allowing random IP/PORT into LAN
-
Sorry wrong person
@johnpoz
It was a joint effort? Under guidance I created the rules. However, the person that helped is no longer able to do so. Long story.Would you suggest going back through the rules and starting over?
So the inbound connection:
Inbound connectivity on the protected machine:
TCP port 25568 (for Datto Windows Agent service)Is really outbound? How does that track? It seems that they are requesting an inbound connection?
How do I see the edit? New to the forum as well.

Here is the KB:

Datto runs on a backup device in the office and backs up PCs in the office. "on the protected machine" is each PC in the office.
-
No, I get what it is saying. We do not have the appliance though and each system has an agent installed on it. The agent talks back to the Datto cloud for backup.
I hope that I am making sense.
-
@wwdot_computers that screams the local firewall on the device your running that agent, not from the internet.. Since that makes zero sense at all that you would have to make
Here is a drawing on their site..
See the local network cloud.. This siris box talking to your protected box... So unless this box is on some other vlan in your local network than the protected machine.. There is no firewall rules needed in pfsense.. But the protected machines local host firewall would have to all that traffic.

You linked the Datto BCDR backup which AFAIK is only via an on site device, either Alto or Sirus.
Do you have Endpoint Backup?

(or others going down the left menu on that page) -
That is an inaccurate representation of our setup as we do not have a Siris box or any other for that mater. Each machine needs to connect to the internet directly for the backup. All of the machines are not able to connect, so I do not think it is a local machine firewall issue.
-
That is correct. We have the Datto Endpoint Backup
Endpoint Backup is our fully cloud-based backup and recovery solution for Windows Servers or PCs. You can leverage its features to restore single files or the entire backup image to a new device without any extra equipment required. Select a topic from the left navigation pane to continue.I am not sure why the tech support linked me that other link. Sorry, was just not looking. However, that being the case, still have the issue :(

Looking at that KB, which I should have caught the first time around, there is not an inbound. I have opened the appropriate ports of outbound, but in the logs, it seems to block 587/443 and such.Ideas?
-
@wwdot_computers yeah open the ports they list outbound - no where in that list does it say anything about the port you were listing.
There is also that 3262 port, but that seems to only be needed for bare metal restore.
edit: most of these rules make zero sense if you have endpoint only
Those ports are not listed in their doc, what do you have in the alias?
edit2: As a troubleshooting tool, create a rule on the top that allows one of your machines your trying to backup any any.. Log its traffic - what ports does it talk on for talking to backup?
Maybe your issue is dns related? And it can't resolve what that list says it needs to be able to resolve.. But looks like it need only 443 outbound, and then one of those 3 ports.
-
Here are the ports in the alias that I have from the rules I posted prior:
-
Well that 3260 and 25xxx ports are not needed per their doc.. And 123 is ntp and wouldn't be tcp, that would be udp.. And while sure the box should sync time it wouldn't do it over tcp.. And it can get time just from pfsense ntp server.. There doc doesn't list that as a requirement that I saw..
Maybe your issue dns related? Validate you can resolve those listed fqdn at the host your trying to backup.
-
Interesting. Can not resolve "dattolocal.net" Ideas?

dattolocal.net
Something is really odd there... I can not resolve it either get servfail - and they clearly failing dnssec
If I ask google, I get this EDE info back about the servfail

I would contact their support - its not something broken in pfsense that is for sure.. Here is a query to 1.1.1.1 and it also comes back empty..

Maybe their doc isn't quite right and there is some specific host.dattolocal.net your suppose to resolve?
But you can see in the ede info, looks like they are not returning the SOA when there is no A record for just the domain dattolocal.net, which is a borked config, it should return a soa.. if there is no record..
See if I ask for something where the record does not exist - you should get back the SOA that tells you hey this NS is authoritative for this domain, and he says there isn't a record for what your asking for.

@johnpoz It's for the device OP doesn't have:
https://www.reddit.com/r/Datto/comments/13dfsgk/dattolocalnet_unable_to_resolve/
"xxxx.dattolocal.net is a dynamic DNS entry managed by Datto which should basically just resolve your Siris's eth0 address. Its mostly used for BMRs and as a pointer when going to device.dattobckup.com to see local Datto devices. ..." -
@SteveITS great thanks. So he doesn't need that - but why do they list it under a dns requirement for endpoint clients.. Not a datto user nor have I heard of it even until today ;)
But from just the quick read through of some docs, I thought I saw something that you can't do like both - you either have a local device or you use endpoint, but endpoint from your comment doesn't require to be able to resolve that - so why would it be in the docs for endpoint client setup?
-
@johnpoz Have not used Endpoint so I can't explain that. I would guess though it's a hostname under it? Or a paste-o on their part? Endpoint came along after their BCDR as I recall.
BCDR backs up snapshot images to (or through) a local device then up to Datto's cloud, and the device/server can instant-start on the BCDR device or in the cloud. Endpoint says it is a snapshot also.
In my experience with Arcserve ShadowProtect, one can only have one snapshot going at a time or they trip on each other. (note with ShadowProtect one can do one job with full+incrementals, and a second full job without incrementals, but can't have two incrementals going on the same drive)
(we have one client on Datto BCDR and many on ShadowProtect)
-
@SteveITS Yes. It did come after the BCDR product. The cloud backup takes an initial snapshot and then incremental ones. Never heard of ShadowProtect though. I may have to check them out.
None of my clients need the BCDR and are more suited for just the Endpoint BKP. It is at the file level, so data can be restored that way. However, from talking to some of the techs, a BMR is still possible.
That being said, what do you think I need to do as far as getting the agents to work behind pfSense? They work fine connected to the VPN, Therefore I know that it is not an endpoint issue. It must be on the firewall. Should I disable all the rules and see what comes through? I do not understand why the firewall is blocking 443 and such, considering it is open via the standard tcp/udp ports. I am running snort and pfBlocker(something. cant remember offhand)
You guys have been great and I appreciate all the info. Thank you for helping me get to the bottom of this one.
-
@wwdot_computers for a test do like I said, put a rule at the top that allows the device to ANY.. Does it work then.. If not its not a pfsense issue.. Log this rule so you can see where its going and what ports.. If they F'd up the doc on for that datto.net thing maybe they missed a port or something?
Unless you some rules in floating blocking outbound? And again anything blocked by pfsense, unless you have created a block rule that doesn't log or you have turned off logging of the default deny.
